Among these cordless rotary hammers, I’d start with the DEWALT DCH133B as the best overall balance of a familiar 1-inch SDS-Plus platform and practical concrete-drilling capacity. The Milwaukee 2912-20 is a strong alternative for M18 users who want a capable brushless tool, while the compact DEWALT DCH172B suits lighter drilling and overhead work. The main tradeoffs are power versus weight, SDS-Plus versatility versus SDS-Max capacity, and bare-tool flexibility versus the cost and convenience of a kit. Battery compatibility matters just as much as the hammer itself, especially when comparing tools across brands or lesser-known platforms. Continue reading for the full breakdown of all 15 cordless rotary hammers and how their differences should shape your choice.

Key Takeaways
- The DEWALT DCH133B is the most balanced starting point: its 1-inch SDS-Plus format suits common concrete drilling without moving to a heavier, more specialized SDS-Max tool.
- The Milwaukee 2912-20 and 2912-22 share a platform but not the same buying proposition: the bare tool favors existing M18 owners, while the kit adds battery and charger convenience.
- Compact tools serve a distinct purpose: the DEWALT DCH172B’s 5/8-inch class is better matched to lighter holes and overhead work than repeated large-diameter drilling.
- SDS-Max is a capacity choice, not a default upgrade: the VEVOR model’s larger accessory system may suit demanding work, but it is less versatile for buyers whose bits are SDS-Plus.
- Battery fit separates practical value from headline specs: several options are bare tools or depend on a particular battery platform, while the Greenworks and Milwaukee kit listings include power components.

Securitoday Cordless SDS Brushless Rotary Hammer Drill for Dewalt 20V MAX Batteries
The Securitoday makes the most sense for buyers who already have DeWalt 20V MAX batteries and want a hammer, drill, and chisel tool without adding another battery platform. Its listed 2.5 joules of impact energy and four functions cover common masonry drilling and light chiseling, while the included bits and case make it more ready to store and use than the bare-tool DEWALT DCH133B. The tradeoff is that the Securitoday lists a lower 1,200 RPM maximum speed than the DEWALT’s 1,500 RPM, and its battery and charger are sold separately. It also lacks the established brand positioning of the DEWALT. I’d favor it for occasional concrete work with existing compatible batteries, not for buyers seeking a complete kit or prioritizing faster drilling.
Pros:- Compatible with a range of DeWalt 20V MAX batteries.
- Four functions include drilling, hammer drilling, chiseling, and chisel-angle adjustment.
- Brushless motor and listed 2.5-joule impact energy suit common masonry tasks.

DEWALT 20V MAX Brushless 1-Inch SDS-Plus Cordless Rotary Hammer, Bare Tool (DCH133B)
The DEWALT DCH133B is a straightforward choice for buyers who want a relatively light cordless rotary hammer from a major tool platform. At a listed 5 pounds, it is lighter than the Milwaukee 2912-20’s listed 7.5 pounds, a meaningful difference for overhead drilling or carrying the tool between jobs. Its 2.6 joules of impact energy and three modes cover drilling, hammer drilling, and chipping, though it does not list the chisel-angle adjustment found on the Securitoday and 20V four-function model. The compromise is the bare-tool format: the battery and charger are not listed as included. I’d choose it over the Securitoday when lower listed weight and a 1,500 RPM maximum matter more than an extra operating mode or included bits.
Pros:- Listed 5-pound weight is lower than the Milwaukee 2912-20’s listed 7.5 pounds.
- Brushless motor and 2.6 joules of impact energy support concrete drilling and chipping.
- Three selectable modes cover drilling, hammer drilling, and chipping.
- Includes a 360-degree side handle and depth rod.
Cons:- Battery and charger are not listed as included.
- Does not list a chisel-angle adjustment mode.
- Accessory package does not include drill bits or a carrying case.
Best for: DeWalt 20V users who want a lighter SDS-Plus hammer for concrete drilling and occasional chipping, especially for overhead or mobile work.
Not ideal for: Buyers who need a complete battery kit, included drill bits, or chisel-angle adjustment.
- Voltage:20V
- Motor:Brushless
- Impact energy:2.6 joules
- Maximum rotational speed:1,500 RPM
- Operating modes:Drill, hammer drill, and chip
- Weight:5 pounds
- Included accessories:360-degree side handle and depth rod

Our verdict“Pick the DCH133B if low listed weight and DeWalt-platform compatibility matter more than a full kit or four-mode versatility.”
Milwaukee 2912-20 M18 FUEL 18V Brushless 1-Inch SDS-Plus Rotary Hammer
The Milwaukee 2912-20 stands apart for AUTOSTOP Control, which senses bind-ups and can help limit the sudden reaction that makes a rotary hammer harder to control. That focus on control gives it a different appeal from the DEWALT DCH133B, which is lighter in the supplied specifications but does not list comparable bind-up sensing. The Milwaukee also offers three speed settings and a brushless motor for users who want more control over how the tool approaches varied work. Its listed 7.5-pound weight is a real tradeoff against lighter choices, and it comes without a case. The product data also gives conflicting power-source information, listing both battery-powered and corded electric, so I’d verify the exact tool configuration before purchase. It suits M18 users who value added control more than low weight or a ready-to-store kit.
Pros:- AUTOSTOP Control senses bind-ups.
- Brushless motor and three speed settings provide adjustable operation.
- Listed drilling capacities include 1.13 inches in wood and 0.5 inches in metal.
- Compatible with the Milwaukee M18 system.
Cons:- Listed weight of 7.5 pounds is higher than the DEWALT DCH133B’s listed 5 pounds.
- Carrying case is not included.
- Product data lists both battery-powered and corded-electric power sources.
Best for: Milwaukee M18 users drilling concrete who prioritize bind-up sensing and speed control over a lightweight build.
Not ideal for: Buyers who need a light tool for sustained overhead work, a case in the box, or unambiguous power-source specifications.
- Compatible system:Milwaukee M18
- Voltage:18V
- Motor:Brushless
- Maximum rotational speed:1,330 RPM
- Speed settings:3
- Control feature:AUTOSTOP Control senses bind-ups
- Weight:7.5 pounds
- Case:Not included
Our verdict“Choose the Milwaukee 2912-20 if you use M18 batteries and value bind-up sensing more than low weight or an included case.”
20V Brushless Cordless SDS Plus Rotary Hammer Drill, 4 Functions, Includes 5 Drill Bits and Gloves (Battery Not Included)
This 20V SDS-Plus model puts four operating functions and handling aids at the center of its offer: drilling, hammer drilling, chiseling, and chisel-angle adjustment, plus a variable-speed trigger, safety clutch, and 360-degree auxiliary handle. That makes it more adaptable for repositioning a chisel than the three-mode DEWALT DCH133B. Its listed 2.5 joules of impact energy matches the Securitoday, and it also claims DeWalt 20V MAX battery compatibility. However, neither battery nor charger is included, and the supplied dimensions of 5 × 5 × 5 inches do not give a useful picture of the tool’s actual size. The five bits and gloves add practical extras, but the specs omit speed and weight, making direct performance comparisons harder. I’d shortlist it for existing DeWalt-battery owners who need the added chisel positioning mode.
Pros:- Four functions include chisel-angle adjustment.
- Brushless motor with listed 2.5-joule impact energy.
- Safety clutch, anti-slip grip, and 360-degree auxiliary handle support control.
- Includes five drill bits and gloves.
Cons:- Battery and charger are not included.
- Supplied 5 × 5 × 5-inch dimensions do not clarify the tool’s actual form factor.
- The product data does not specify rotational speed or weight.
Best for: DeWalt 20V MAX owners who need drilling, chiseling, and adjustable chisel positioning, with an auxiliary handle for control.
Not ideal for: Buyers who need batteries included or want clearly stated weight, rotational speed, and tool dimensions before choosing.
- Voltage:20V
- Motor:Brushless
- Impact energy:2.5 joules
- Chuck type:SDS-Plus
- Maximum chuck size:10 mm
- Functions:Drilling, hammer drilling, chiseling, and chisel-angle adjustment
- Compatible batteries:DeWalt 20V MAX; battery not included
- Included accessories:Five drill bits and gloves
Our verdict“Choose this model if chisel-angle adjustment and DeWalt 20V battery compatibility are priorities, and you can accept incomplete performance specifications.”
Seesii 1-Inch Cordless SDS-Plus Rotary Hammer Drill, 2.5 J, Brushless, 4-Mode
The Seesii is the most job-ready option in this group: unlike the bare-tool DEWALT DCH133B and Milwaukee 2912-20, it includes two 4.0 Ah batteries, a charger, bits, chisels, a depth gauge, and a carrying case. Four modes cover drilling and chiseling, while the listed 2.5-joule impact energy, safety clutch, and anti-kickback protection point to a tool designed for practical masonry work rather than minimal carry weight. The added kit is useful for buyers starting without compatible batteries, but battery runtime is not specified, so the two packs do not reveal how long a work session will last. Its listed impact rate of 4,800 BPM is also lower than the Securitoday’s 6,200 BPM. I’d favor Seesii for a self-contained setup, while established-platform owners may prefer a bare tool that fits batteries they already have.
Pros:- Includes two 4.0 Ah batteries and a charger.
- Four modes support drilling and chiseling tasks.
- Safety clutch and anti-kickback protection are listed.
- Kit includes drill bits, pointed and flat chisels, depth gauge, and carrying case.
Cons:- Battery runtime is not specified.
- Listed 4,800 BPM impact rate is lower than the Securitoday’s 6,200 BPM.
- The supplied information does not identify a clear third-party battery platform.
Best for: DIYers and property-maintenance buyers who need a cordless masonry setup with batteries, charger, bits, chisels, and case included.
Not ideal for: Owners invested in DeWalt or Milwaukee batteries who prefer to buy a bare tool, or buyers who need a stated runtime for planning long work sessions.
- Motor:Brushless
- Impact energy:2.5 joules
- Power:900 W
- Impact rate:4,800 BPM
- Operating modes:4
- Maximum concrete capacity:1 inch (26 mm)
- Batteries included:2 × 4.0 Ah
- Included accessories:Charger, three SDS-Plus bits, pointed and flat chisels, depth gauge, and carrying case
Our verdict“Pick the Seesii if you want a ready-to-use kit with batteries and masonry accessories instead of a bare tool tied to a battery platform.”
DEWALT 20V MAX Brushless Cordless Rotary Hammer, D-Handle, 1-Inch
I’d choose the DEWALT DCH133B for regular anchor holes and similar concrete drilling where a 1-inch capacity is useful but a larger, heavier hammer would be more than the job needs. Its 2.6 ft-lb impact energy and brushless motor give it more headroom than the lighter DEWALT DCH172B, which is capped at 5/8-inch drilling and 1.4 joules. The DCH133B also reaches up to 5,500 strokes per minute, while its 5.9-pound weight helps keep it manageable in tighter work areas. The tradeoff is that it is a tool-only purchase, so the battery and charger must be sourced separately. I’d also look to the DCH293B for more impact energy and vibration control when heavier, longer sessions matter more than compact handling.
Pros:- 1-inch concrete capacity suits common anchor and mounting work
- Brushless motor is designed for efficient operation and long service life
- Up to 5,500 strokes per minute supports steady drilling progress
- 5.9-pound weight and compact design help in restricted work areas
Cons:- Battery and charger are sold separately
- Less impact energy than the DEWALT DCH293B for demanding drilling
- No vibration-control feature is listed in the supplied specifications
Best for: Concrete and masonry installers who need a compact 1-inch SDS-Plus hammer for routine drilling and already own compatible DEWALT 20V batteries.
Not ideal for: Buyers without a DEWALT 20V battery or those doing sustained heavy drilling who would benefit from the DCH293B’s higher impact energy and vibration control.
- Model:DCH133B
- Voltage:20V
- Motor:Brushless
- Chuck type:SDS Plus
- Impact energy:2.6 ft-lb
- Maximum speed:1,500 rpm
- Impact rate:Up to 5,500 strokes per minute
- Concrete capacity:1 inch
- Weight:5.9 pounds
Our verdict“Choose the DCH133B for compact, routine 1-inch concrete drilling if you already have DEWALT 20V batteries.”
VEVOR 20V Cordless SDS-Max Rotary Hammer Drill with Two Batteries
The VEVOR SDS-Max is the outlier here: it pairs a larger SDS-Max chuck with up to 7 J of impact energy and includes two 4.0Ah batteries and a charger. That kit gives buyers a ready-to-work setup, unlike the DEWALT DCH293B, which is sold as a bare tool. Its three modes cover drilling, hammer drilling, and chiseling, making it a better fit for mixed masonry tasks than the drill-focused DEWALT DCH133B. There are significant uncertainties in the supplied specifications, though: the tool is described as a 20V battery model, while another listing says 110 volts, and the stated maximum speed is only 500 rpm with no other settings specified. I’d favor it only if SDS-Max capacity and the included kit outweigh the appeal of clearer, more established spec profiles.
Pros:- SDS-Max chuck and up to 7 J impact energy suit demanding masonry work
- Three modes include dedicated chiseling
- Two 4.0Ah batteries and a charger are included
- LED light, depth gauge, and adjustable chisel angle support controlled work
Cons:- Supplied voltage information conflicts between 20V battery power and a 110-volt listing
- Maximum speed is listed as 500 rpm, with no additional speed settings specified
- SDS-Max bits are a different fit from the SDS-Plus systems used by the DEWALT models in this roundup
Best for: Masonry workers who need an SDS-Max cordless tool for drilling and chiseling and want batteries, charger, and basic accessories in the box.
Not ideal for: Buyers who need verified electrical specifications, higher stated rotational speed, or an SDS-Plus tool for a narrower range of bits.
- Chuck type:SDS-Max
- Voltage:20V battery system; listing also states 110 volts
- Battery capacity:Two 4.0Ah lithium-ion batteries
- Impact energy:Up to 7 J
- Maximum rotational speed:500 rpm
- Impact rate:Up to 2,700 bpm
- Maximum power:600 W
- Modes:Drilling, hammer drilling, chiseling
- Included components:Carrying case, charger, depth gauge, drill bit, point chisel, wrench, two batteries
Our verdict“Pick the VEVOR if you want an SDS-Max drilling-and-chiseling kit with batteries included and can accept uncertainty in its listed specifications.”
DEWALT 20V MAX Brushless Cordless SDS Plus Rotary Hammer, 5/8 in. (DCH172B)
For overhead fastening, tight access, and smaller holes, I’d put the DEWALT DCH172B ahead of the larger DCH133B. At 4.59 pounds with a 5/8-inch maximum drilling capacity, it trades reach and impact strength for a lighter tool that is easier to position for repeated mounting work. Its 1.4 joules of impact energy is well below the DCH133B’s 2.6 ft-lb, so this is not the one I’d select for larger or more demanding holes. The listed vibration control is a useful distinction for hands-on work, and the brushless motor supports a compact cordless setup. It includes a side handle and depth rod, but no battery or charger is listed, so existing DEWALT 20V owners are the natural audience.
Pros:- 4.59-pound weight is the lightest stated option among these DEWALT rotary hammers
- Compact dimensions help with overhead and confined-space drilling
- Vibration control reduces vibration felt at the handles
- Includes a 360-degree side handle, belt hook, and depth rod
Cons:- 5/8-inch maximum drilling capacity limits hole size
- 1.4 joules of impact energy is below the DCH133B and DCH293B
- Battery and charger are not listed among the included components
Best for: Electricians and installers making frequent small anchor holes overhead or in confined spaces who already have DEWALT 20V batteries.
Not ideal for: Concrete crews drilling up to 1 inch or buyers who need greater impact energy and a battery included.
- Model:DCH172B
- Voltage:20V
- Chuck type:SDS Plus
- Impact energy:1.4 joules
- Maximum drilling capacity:5/8 inch
- Weight:4.59 pounds
- Motor:Brushless
- Maximum power:300 W
- Included components:360° side handle, belt hook, rotary hammer, depth rod
Our verdict“Choose the DCH172B for lighter-duty, smaller-hole work where low weight and vibration control matter more than drilling capacity.”
Deshuo 1″ SDS-Plus Lightweight Rotary Hammer Drill
The Deshuo DS-LD26 brings four operating modes, a safety clutch, and an accessory set to concrete work, but it is corded, not cordless. That distinction matters in this roundup: unlike the battery-powered DEWALT DCH133B, it needs a 120V outlet and is less convenient where extension cords are awkward or unavailable. In return, the supplied kit includes drill bits, chisels, a depth gauge, and a case, while its rotary-only, hammer-only, and chisel-position settings cover tasks beyond drilling. At 7.19 pounds, it is also heavier than the compact DEWALT DCH172B, though the listed vibration control may help during overhead or downward work. I’d treat it as a corded comparison for buyers prioritizing included accessories and mode flexibility, not as a substitute for cordless mobility.
Pros:- Four modes cover rotary drilling, hammer drilling, hammer-only work, and chisel positioning
- Includes three drill bits, two chisels, a depth gauge, and a carrying case
- Safety clutch and vibration control support user control
- 1-inch SDS-Plus chuck accommodates larger bits than the DEWALT DCH172B
Cons:- Corded 120V power does not meet a cordless tool requirement
- At 7.19 pounds, it is heavier than the DEWALT DCH172B for overhead use
- SDS-Plus chuck is not compatible with standard or SDS-Max bits
Best for: DIYers and maintenance workers who have outlet access and want a multi-mode hammer drill with bits, chisels, and a case included.
Not ideal for: Buyers specifically seeking cordless mobility, working far from outlets, or doing heavy demolition beyond the stated intended use.
- Model:DS-LD26
- Power source:Corded electric
- Voltage:120V
- Amperage:9A
- Chuck size:1 inch, SDS-Plus
- Impact energy:2.21 ft-lb (3 joules)
- Maximum speed:1,100 rpm
- Weight:7.19 pounds
- Modes:Rotary hammer, rotary only, hammer only, chisel position adjustment
Our verdict“Choose the Deshuo only if corded power is acceptable and its four modes and included accessories matter more than cordless convenience.”
DEWALT DCH293B 20V MAX XR Brushless 1-1/8-Inch SDS Plus Rotary Hammer, Tool Only
Among the cordless SDS-Plus options here, the DEWALT DCH293B is the choice I’d make when drilling capacity and control matter more than keeping the tool as light as possible. Its 3.5 joules of impact energy exceeds the DCH133B’s listed 2.6 ft-lb, and the 1-1/8-inch SDS-Plus capacity gives it room for larger holes than either the DCH133B or the compact DCH172B. The E-Clutch helps manage bind-up, while SHOCKS Active Vibration Control is a practical advantage for extended drilling. It also supports the D25304DH dust-extraction attachment, though that accessory is sold separately. The main compromise is the bare-tool format: battery and charger are not included. I’d skip it for small anchor work where the lighter DCH172B is easier to handle.
Pros:- 3.5 joules of impact energy supports more demanding drilling than the DCH133B
- 1-1/8-inch SDS-Plus capacity exceeds the DCH133B and DCH172B
- E-Clutch helps control bind-up situations
- SHOCKS Active Vibration Control and dust-extraction compatibility support controlled work
Cons:- Battery and charger are not included
- Dust-extraction attachment is sold separately
- Its greater drilling capacity is unnecessary for small-hole work where the DCH172B is more compact
Best for: Concrete contractors and installers drilling larger holes who already own DEWALT 20V batteries and value clutch and vibration-control features.
Not ideal for: Occasional users seeking a compact tool for small holes or buyers who need a battery and charger in the package.
- Model:DCH293B
- Voltage:20V
- Chuck type:SDS Plus
- Maximum drilling capacity:1-1/8 inches
- Impact energy:3.5 J
- Maximum rotational speed:1,000 rpm
- Number of speeds:3
- Motor:Brushless
- Dust extraction compatibility:D25304DH attachment
Our verdict“Pick the DCH293B for larger cordless SDS-Plus drilling and added control features if you already have DEWALT 20V batteries.”
Greenworks 24V Cordless Brushless Rotary Hammer with 4Ah Battery and Charger
The Greenworks is a practical pick for buyers who want a cordless hammer for occasional concrete drilling and light chiseling without assembling a kit from separate tools. Its 2J impact energy and four modes cover more than basic hammer drilling, while the included 4Ah battery and charger make it more job-ready than the bare-tool DEWALT DCH273B. The SDS Plus chuck also makes bit changes straightforward. At 5.44 lb, it is lighter than the Milwaukee 2712-20, though that weight can still tire an arm during long overhead sessions. Its 1,000 rpm ceiling is modest beside the Milwaukee’s 1,400 rpm, and the supplied information does not list drilling capacities. I’d choose it for portable, mixed DIY work rather than demanding daily concrete drilling.
Pros:- Includes a 4Ah battery and charger, unlike the bare-tool DEWALT DCH273B.
- Four modes cover drilling, hammer drilling, chiseling, and chisel-position adjustment.
- Brushless motor and SDS Plus chuck support efficient work and convenient bit changes.
- 5.44 lb listed weight is lower than the Milwaukee 2712-20’s 6.9 lb.
Cons:- Maximum listed speed of 1,000 rpm is lower than the Milwaukee 2712-20’s 1,400 rpm.
- The 5.44 lb tool may feel tiring during extended overhead use.
- Product data does not specify maximum drilling capacities.
Best for: DIYers and property owners who need a complete cordless tool for occasional concrete drilling and light chiseling.
Not ideal for: Crews drilling concrete for long shifts or overhead, since the listed speed is modest and its 5.44 lb weight can still fatigue the user.
- Voltage:24V
- Battery:4Ah lithium-ion; included with charger
- Impact energy:2J
- Maximum rotational speed:1,000 rpm
- Modes:Drilling, hammer drilling, chisel, chisel rotation lock
- Chuck:SDS Plus
- Weight:5.44 lb
Our verdict“Choose the Greenworks if you want a relatively light, four-mode rotary hammer with its battery and charger included for occasional home and property work.”
Seesii 1-Inch Cordless SDS-Plus Rotary Hammer Drill, 2.8 J, Brushless Motor
Seesii leads this group on listed impact energy: its 2.8J rating exceeds the Greenworks 24V’s 2J and the DEWALT DCH273B’s 2.1J. That gives buyers a stronger paper case for drilling into concrete, while the two 4Ah batteries, charger, bits, chisels, depth gauge, and case make the package convenient for a DIYer starting without accessories. Four modes add chisel positioning, a useful detail when setting an angle before work. The tradeoff is that the product is described for light contracting and DIY, so I would not treat its higher impact figure alone as proof of heavy-duty jobsite endurance. Its stated compatibility with Ma-kita batteries may appeal to some owners, but buyers should verify fit rather than assume broad platform interchangeability.
Pros:- Listed 2.8J impact energy is higher than the Greenworks 24V and DEWALT DCH273B figures.
- Two 4Ah batteries provide a spare for work away from an outlet.
- Four modes include chisel positioning as well as drilling, hammer drilling, and chiseling.
- Includes bits, chisels, a depth gauge, charger, and storage case.
Cons:- Product description positions it for light contracting and DIY rather than demanding daily use.
- Specified compatibility with Ma-kita batteries may limit usefulness within other battery systems.
- No tool weight is provided in the supplied specifications, making handling comparisons difficult.
Best for: DIYers or light-duty contractors who want a high listed impact-energy rating and a ready-to-use kit with spare battery and accessories.
Not ideal for: Daily heavy-duty users who need established jobsite support or buyers expecting the batteries to work across a broad tool platform without checking compatibility.
- Voltage:18V
- Batteries:Two 4.0Ah batteries
- Impact energy:2.8J
- Impact rate:Up to 5,000 BPM
- Maximum rotational speed:1,150 rpm
- Concrete drilling capacity:1 in (26 mm)
- Chuck and modes:SDS-Plus; drill, hammer drill, chisel, chisel positioning
- Included accessories:Charger, drill bits, chisels, depth gauge, storage case
- Warranty support:24 months of technical support
Our verdict“Pick the Seesii for DIY and light contracting when a spare battery and a broad accessory set matter as much as drilling capability.”
DEWALT 20V MAX Brushless 1-Inch SDS Rotary Hammer (DCH273B), Bare Tool
The DCH273B makes a strong case for buyers who spend enough time drilling concrete to care about vibration at the handles. Its SHOCKS Active Vibration Control is the defining difference from the Greenworks 24V, which lists a vibration-reducing brushless motor but does not specify a comparable control system. The DEWALT also provides 2.1 joules of impact energy and three modes for drilling, hammer drilling, and chipping. Compared with the Seesii’s higher 2.8J figure and four modes, it offers less listed impact energy and fewer settings, but adds a named vibration-control feature and stated compatibility with a dust extractor for OSHA Table 1 compliance. This is a bare tool: buyers need a battery and charger, and the extractor is separate.
Pros:- SHOCKS Active Vibration Control is designed to reduce vibration felt at the handles.
- Brushless motor and 2.1 joules of impact energy suit concrete drilling and chipping tasks.
- Compatible with the DWH303DH extractor for OSHA Table 1 compliance.
- Includes a 360-degree side handle, depth rod, and adjustable hook.
Cons:- Bare tool only; battery and charger are not included.
- Three modes provide fewer options than the four-mode Seesii and Greenworks models.
- OSHA Table 1 compliance requires the separate DWH303DH extractor.
Best for: DEWALT 20V MAX owners who drill concrete regularly and value vibration control or plan to use a compatible dust extractor.
Not ideal for: First-time cordless-tool buyers seeking a complete kit, or users who need four-mode chisel positioning without buying additional equipment.
- Voltage:20V MAX
- Motor:Brushless
- Impact energy:2.1 joules
- Maximum rotational speed:1,100 rpm
- Modes:Drill, hammer drill, chip
- Weight:6.4 lb
- Dimensions:13 × 4.2 × 8.6 in
- Included components:Rotary hammer, 360° side handle, depth rod, adjustable hook
- Warranty:3-year limited warranty
Our verdict“Choose the DCH273B if you already own DEWALT 20V MAX batteries and prioritize vibration control for repeated concrete work.”
Milwaukee M18 Cordless SDS Plus Rotary Hammer, Bare Tool
The Milwaukee 2712-20 is the straightforward platform pick for M18 owners who want a capable cordless concrete tool without buying another battery system. Its 1,400 rpm maximum speed is the highest listed among these five products, and the 0–4,900 BPM impact rate, anti-vibration system, and stop-rotation feature suit drilling and chipping tasks. Against the DEWALT DCH273B, it turns faster on paper but lists 1.7 ft-lb of impact energy and weighs 6.9 lb; the DEWALT instead gives a specified 2.1 joules and named active vibration control. This Milwaukee is also a bare tool, unlike the Greenworks and Seesii kits. Its 1-inch concrete capacity is useful, though buyers should account for the battery and charger separately.
Pros:- 1,400 rpm maximum speed is higher than the listed speed of the other products in this batch.
- Anti-vibration system and stop-rotation feature support drilling and chipping versatility.
- Listed concrete capacity reaches 1 inch, with 2.5-inch core bit capacity.
- Five-year warranty is longer than the DEWALT DCH273B’s listed three-year limited warranty.
Cons:- Battery and charger are not included.
- At 6.9 lb, it is heavier than the Greenworks 24V’s listed 5.44 lb.
- Listed impact energy of 1.7 ft-lb is lower than the DEWALT DCH273B’s 2.1 joules when comparing the stated figures.
Best for: Existing Milwaukee M18 users who need a 1-inch-capacity SDS Plus hammer for concrete drilling and occasional chipping.
Not ideal for: Buyers without M18 batteries, or those prioritizing a complete kit, lower tool weight, or higher listed impact energy.
- Voltage:18V
- Motor:Brushless
- Chuck:SDS Plus
- Maximum rotational speed:0–1,400 rpm
- Impact rate:0–4,900 BPM
- Impact energy:1.7 ft-lb
- Concrete capacity:1 in
- Tool weight:6.9 lb
- Battery and warranty:Li-Ion battery not included; 5-year warranty
Our verdict“The 2712-20 suits M18 owners who want fast rotation and useful concrete capacity, but it is less appealing as a first cordless tool because it is sold bare.”
Milwaukee 2912-22 M18 FUEL 1-Inch Cordless SDS Plus Rotary Hammer Kit
For buyers who want a more complete work package, the Milwaukee 2912-22 pairs 2 ft-lb of impact energy with AUTOSTOP kickback control and an anti-vibration system. That combination gives it a stronger safety-and-comfort pitch than the bare Milwaukee 2712-20, while two 6.0Ah batteries and a fast charger make it better suited to extended cordless sessions than the Greenworks kit with one 4Ah battery. The tradeoff is substantial kit bulk: its listed 21.8 lb weight is far above the tool-only weights provided for the other models, so I would check whether that figure fits the way you transport and handle tools. Only one speed is listed, too. This is the most convincing choice here for buyers investing in a supported M18 kit, not for someone seeking the lightest hammer.
Pros:- AUTOSTOP kickback control helps limit over-rotation.
- Two 6.0Ah batteries and a fast charger are included, unlike the bare Milwaukee 2712-20.
- 2 ft-lb impact energy and brushless motor support demanding drilling and chiseling tasks.
- Anti-vibration system is designed to improve comfort during use.
Cons:- Listed kit weight of 21.8 lb is much higher than the tool-only weights given for the other models.
- Only one speed is listed, limiting the available speed information for different materials and tasks.
- Its larger battery kit may be more than occasional DIY users need.
Best for: M18 users and contractors who want a complete rotary-hammer kit, spare high-capacity battery, and kickback control for concrete work.
Not ideal for: Buyers prioritizing a light, compact setup or people who only need an occasional-use hammer and do not need two batteries.
- Voltage:18V
- Motor:Brushless
- Impact energy:2 ft-lb
- Maximum rotational speed:1,330 rpm
- Impact rate:4,800 BPM
- Battery kit:Two 6.0Ah batteries and fast charger
- Safety and comfort features:AUTOSTOP kickback control; anti-vibration system
- Weight:21.8 lb
- Warranty:Limited 5-year warranty
Our verdict“Choose the 2912-22 if you want a complete M18 kit with kickback control and two high-capacity batteries, and can accept the listed weight and bulk.”
How We Picked
I ranked these cordless rotary hammers by how well their stated format and features match common concrete-drilling needs. I weighed SDS-Plus or SDS-Max compatibility, bit capacity, brushless motor claims, operating modes, battery and charger inclusion, and the handling implications of compact or D-handle designs. I also considered whether a product description gives buyers enough clarity about platform fit and intended work; generic or adapter-style listings deserve more caution than established tool-platform options.
The ordering favors tools with a clear role, recognizable battery ecosystem, and useful balance of drilling capability and day-to-day practicality. That puts the DEWALT DCH133B and Milwaukee 2912-20 near the front, while compact, larger-format, and less clearly specified choices serve narrower needs. Kit contents affect convenience, but they do not automatically make a hammer more capable. I treat stated specifications as a guide rather than a guarantee of real-world output, since performance also depends on bit choice, concrete, battery condition, and workload.
Factors to Consider When Choosing Cordless Rotary Hammers
Before choosing a cordless hammer, I’d match the tool to the holes you actually drill, then check the battery platform and accessories you already own. A larger capacity or longer feature list can add weight and expense without helping with routine anchor holes. These factors help separate a practical everyday tool from a model that only looks more capable on paper.
Choose SDS-Plus or SDS-Max Around Your Work
SDS-Plus is the more versatile choice for many home, renovation, and general trade tasks, with a broad range of commonly used bits and a manageable tool size. SDS-Max is intended for larger, more demanding drilling and chiseling, but its bits are a separate system and tend to make the setup more specialized. A common mistake is buying the largest format available for occasional small anchor holes; that can mean extra bulk without a useful payoff. Check the bit diameters and accessories your jobs require before choosing the chuck system. If your work varies between small holes and occasional heavier tasks, staying with SDS-Plus may be the more practical compromise.
Match Capacity to Hole Size and Workload
Capacity labels such as 5/8-inch, 1-inch, and 1-1/8-inch help describe a tool’s class, but they are not a promise that every hole at that size will be quick or comfortable. Repeated large holes in hard concrete demand more from the hammer, battery, bit, and operator than occasional smaller holes. For light anchor work or overhead drilling, a compact model may be easier to control than a larger hammer. For frequent heavy drilling, prioritize a tool explicitly suited to that workload rather than relying on a high capacity figure alone. Leave margin between your usual hole size and the tool’s stated limit to reduce strain on both the user and equipment.
Treat Battery Compatibility as Part of the Purchase
A bare tool can be a sensible fit when you already own compatible batteries and a charger, but it may be an incomplete purchase for someone entering a new platform. Confirm the exact battery family and voltage before buying; similar-looking packs are not necessarily interchangeable across brands or tool lines. Kit versions simplify setup by including power components, although the included battery may not be the best match for extended heavy work. Battery capacity also affects runtime and can add weight, changing the balance of a compact hammer. Compare the total setup you need, not just the tool listing.
Decide Whether You Need Hammer-Only or Multi-Mode Use
Rotary hammers commonly offer modes for rotary hammer drilling, rotation-only drilling, and chiseling, but mode availability varies by model. More modes can make one tool useful across more tasks, yet they do not turn it into a replacement for every drill or demolition tool. Check which functions the manufacturer specifies and whether the included accessory setup supports your planned work. Buyers sometimes assume a four-mode label means the tool is equally capable in every mode; capacity and control can differ substantially. If your work is mainly concrete holes, prioritize drilling performance and handling over a mode count you rarely use.
Balance Tool Weight, Grip, and Overhead Control
A hammer’s weight and grip layout shape fatigue, accuracy, and comfort across a full day more than a spec sheet can suggest. Compact and lower-capacity tools often make sense for overhead work or tight spaces, while a D-handle can suit certain drilling positions and heavier tasks. A larger hammer may feel steadier in demanding work but tiring during repeated work above shoulder height. Consider the weight with the battery installed, not just the bare tool, and check whether the handle design suits your stance. If possible, prioritize control and reach for the holes you drill most often rather than buying extra capacity you rarely use.
Pay for Features That Match Your Work
Spending more makes sense when it buys capability you will use: a suitable SDS system, a better fit for repeated drilling, useful vibration control, or a kit that fills a genuine battery gap. Brushless motors are a common feature in this group, but the label alone does not settle which tool is best; ergonomics, platform, and intended capacity still matter. For occasional household drilling, a simpler model may be a better fit than a premium hammer designed for more regular work. Avoid choosing by included bits or gloves alone, since accessories do not make up for a mismatch in chuck system or capacity. Set your likely workload first, then pay for features that solve a real limitation.
Frequently Asked Questions
Should I choose the DEWALT DCH133B or the Milwaukee 2912-20?
I’d choose between them based first on the battery platform already in your workshop. Both are brushless, 1-inch SDS-Plus options, so their general role is similar, but an existing DEWALT 20V MAX or Milwaukee M18 battery setup can make one a simpler bare-tool purchase. If you own neither platform, compare the full cost and contents of the tool-and-battery setup rather than deciding from the tool name alone. Also compare grip, mode needs, and the specific work capacity stated by each listing. Neither is automatically the better choice for every concrete job.
Is a 5/8-inch cordless rotary hammer enough for home projects?
A 5/8-inch-class hammer can suit many lighter household tasks, such as drilling smaller holes for anchors and similar fixings in masonry or concrete. It is a less suitable choice if your work regularly calls for larger holes, repeated heavy drilling, or substantial chiseling. Think about your largest routine bit, not an occasional one-off task that could be handled another way. A compact tool may also be easier to position for overhead work or in tight spaces. If your projects are likely to grow, compare the compact model’s limits with a 1-inch SDS-Plus option before committing.
Does an SDS-Max cordless hammer accept my SDS-Plus bits?
SDS-Max and SDS-Plus are different bit systems, so you should not assume that your SDS-Plus bits will fit an SDS-Max hammer directly. An adapter may be available for some combinations, but it can add length and may not be suitable for every job or accessory. Check the tool maker’s guidance and the bit compatibility details before planning around an adapter. If most of your existing accessories are SDS-Plus, an SDS-Plus hammer is usually the simpler match. Choose SDS-Max when the larger system genuinely fits your workload and you are prepared for its separate accessories.
Is a bare tool or a battery kit the better buy?
A bare tool is usually the more straightforward choice if you already own compatible batteries and a charger for that exact platform. If you do not, a kit can save the hassle of sourcing power components separately and makes it easier to start using the hammer. Check the battery capacity included, since a small pack may be less suitable for sustained heavy drilling than a larger one. Remember that packs add weight, which can change the balance of a compact tool. Compare what you already own with the complete setup you need before choosing.
Can a cordless rotary hammer replace my regular drill or a demolition hammer?
A rotary hammer is designed to make drilling into concrete and masonry easier than relying on a typical drill’s hammer function. Many models also offer rotation-only or chiseling modes, but their usefulness depends on the specific tool and task. They are not a universal substitute for a regular drill when you need a lighter tool for repeated work in wood or metal. Nor should a compact SDS-Plus hammer be treated as a dedicated demolition tool for extensive concrete removal. Choose based on your main material and workload, and keep other tools for jobs that exceed the hammer’s intended role.
Conclusion
For most buyers seeking a capable everyday cordless concrete tool, I’d choose the DEWALT DCH133B as best overall, especially if the 20V MAX battery platform is already in your kit. The best value depends on what you own: the DEWALT or Milwaukee bare tool can make sense for existing battery users, while the Greenworks or Milwaukee kit listings offer a more ready-to-use route if their platforms suit you. For a best premium direction, I’d look at the Milwaukee 2912-22 kit or the larger-capacity DEWALT DCH293B when the extra capability fits regular work. For beginners and lighter projects, the compact DEWALT DCH172B is easier to justify than a heavier hammer built for bigger holes. For specific needs, choose the VEVOR SDS-Max for a genuine larger-bit workload, the D-handle DEWALT for a grip style that suits your drilling position, or a 1-inch SDS-Plus model for general concrete work; confirm battery and bit compatibility before deciding.
