The 4 Best Cordless Rotary Hammers of 2026
Every remodel hits the moment when a regular drill gives up: concrete, block, brick. Anchoring a vanity to a block wall, driving Tapcons in a basement, mounting a handrail to concrete. No drill will do it — you need an SDS rotary hammer. The pneumatic hammering mechanism pounds while it spins, and chews through concrete like butter.
Here are the 4 cordless rotary hammers I recommend in 2026, from the best-value pick to the pro-grade beasts I see on job sites every day.
How to choose a cordless rotary hammer: what really matters
- Impact energy (joules): the number that matters most, more than voltage. For residential anchors and Tapcon screws, 1.5 to 2 joules is plenty. More joules = bigger holes, faster — but also more weight.
- SDS Plus: the slotted-bit system that locks in on its own. Everything on this list is SDS Plus, the standard for residential and light commercial work (holes up to 1").
- Brushless motor: nearly mandatory in rotary hammers: more power per charge and motors that survive the pounding.
- Battery platform: buy the rotary hammer that matches the batteries you already own. Starting a new ecosystem for one tool gets expensive fast.
- Bare tool vs. kit: "tool only" means no battery or charger included. Great if you already own batteries; if not, price out the full kit before comparing.
- Work modes: the good ones have 3 modes: drill, hammer drill, and chisel. Chisel-only mode is for light chipping and chasing.

Our pick
1. RYOBI ONE+ HP 18V Brushless 5/8" SDS — best value if you already own 18V batteries
The RYOBI ONE+ HP 18V is a compact brushless SDS rotary hammer that costs a fraction of the big brands. It's sold as a bare tool (no battery or charger included), making it the ideal buy if you already own 18V batteries and need to drill concrete occasionally without spending a fortune.
For anchors, Tapcons, and holes up to 5/8" in concrete and block, it's more than enough. It's not the beast for daily demolition, but for the remodeler who drills concrete a few times a month, the price-to-performance ratio is hard to beat.
- Priced far below the pro brands
- Brushless motor: more efficient and longer-lasting
- Compact and light for its class
2. DeWalt DCH273B 20V MAX XR 1" — the contractor favorite
The DCH273B is the cordless rotary hammer I see most on job sites: 2.1 joules of impact energy, brushless motor, and a 1" SDS Plus chuck. It drills concrete fast, and the vibration control is noticeable on long days.
It's sold as a bare tool in the 20V MAX ecosystem, the biggest in the business. If you already own DeWalt batteries, it's the logical buy: plenty of power for anchors, rod hanging, and concrete fastening.
- 2.1 joules: serious concrete-drilling power
- Vibration control you feel on long jobs
- 20V MAX ecosystem with hundreds of tools
3. Milwaukee 2712-20 M18 FUEL 1" — power for daily jobsite work
The Milwaukee 2712-20 from the M18 FUEL line is DeWalt's direct rival: a 1" SDS Plus rotary hammer with brushless motor, 360-degree handle, and build quality made to last years on site. In pro hands, it drills concrete all day without breaking a sweat.
If your shop already runs on M18 batteries, there's not much to think about: it's the natural pick and one of the most powerful in its class.
- Pro-grade power and durability
- 360° handle for better control
- Huge M18 ecosystem
4. Bosch GBH18V-26 18V 1" — control and low vibration
The Bosch GBH18V-26 is the 18V 1" SDS Plus rotary hammer from the brand that invented the rotary hammer. It stands out for vibration control and excellent balance: it drills concrete with authority without punishing your hands.
A great choice if you value precision and already own Bosch 18V batteries. For anchors and fasteners in residential remodeling, it delivers with room to spare.
- Excellent vibration control
- Brand with decades in rotary hammers
- Balanced and comfortable in long use
In-depth buying guide
The most common mistake is buying too big a rotary hammer "just in case." A 1" SDS Plus covers 95% of residential work: anchors, Tapcons, rebar. SDS Max is for serious demolition and weighs twice as much. Don't pay for capacity you'll never use.
My rule: pick your battery brand first. Between DeWalt, Milwaukee, and Bosch the real performance gap is small; the big gap is not having to buy another charger and more batteries. And if you only drill concrete a few times a year, the RYOBI as a bare tool saves you hundreds doing the same job.
Jobsite tip: always use sharp SDS bits and let the hammer do the work — pushing hard only overheats the motor and wears the bit. And for concrete dust indoors, a HEPA-filter vacuum next to the hole is worth its weight in gold.
Frequently asked questions
Does a rotary hammer replace a regular drill?
No. Rotary hammers are for concrete, block, and brick. For wood, drywall, and metal, a regular drill/driver is still better: lighter, more precise, and cheaper. They're complementary tools.
What does "bare tool" or "tool only" mean?
You're buying just the tool, with no battery or charger. It pays off if you already own batteries on that platform; if not, price the full kit before comparing.
SDS Plus or SDS Max?
SDS Plus (10 mm) is the standard for holes up to 1⅛" in residential and light commercial work. SDS Max (18 mm) is for demolition and heavy drilling. For home remodeling, SDS Plus is plenty.
Can I use regular bits in an SDS rotary hammer?
Chuck adapters exist, but it's not ideal: you lose the hammering action and the adapter makes the tool longer. Better to keep a regular drill for standard bits.
Final verdict
If you already own 18V batteries and want the best value, the RYOBI ONE+ HP 18V Brushless gets the job done for far less money. For daily pro use, the DeWalt DCH273B is the jobsite standard, with the Milwaukee 2712-20 right behind it if your ecosystem is M18. Prioritize control and comfort? The Bosch GBH18V-26 won't disappoint. Pick your battery platform and start drilling concrete.
