Best Rotary Hammers 2026: Top 5 SDS-Plus Picks for Concrete & Masonry

A rotary hammer is the single most important tool for anyone working with concrete, brick, or block. The difference between a good SDS-Plus hammer and a bad one is the difference between drilling a clean 1/2" hole in 8 seconds or spending 2 minutes burning through a bit. Here are the 5 best options in 2026.

1. Bosch GBH18V-26D — Best Overall

The Bosch GBH18V-26D is the rotary hammer most contractors reach for in 2026. At 2.0 joules of impact energy it handles every residential anchor hole — Tapcons, wedge anchors, sleeve anchors — without hesitation. The brushless motor is efficient enough that a ProCORE 4Ah battery lasts through a full day of anchor installation.

What makes it stand out: The vibration control system is genuinely effective — after 200 holes your wrists are not destroyed. The integrated dust collection port works with Bosch's dust extraction attachments for interior work.

Who should buy it: Anyone not already committed to DeWalt or Milwaukee. If you are starting fresh or building out a new battery platform, Bosch 18V ProCORE is the system to be on.

• Impact energy: 2.0 joules
• Chuck: SDS-Plus
• Weight: 5.5 lbs bare
• Modes: Drill, hammer drill, hammer only

2. DeWalt DCH273B — Best for DeWalt Users

The DeWalt DCH273B leads the pack on impact energy at 2.1 joules — slightly ahead of the Bosch — and slots perfectly into the 20V MAX ecosystem most North American contractors are already on. The SHOCKS active vibration control is among the best in class and the tool-free chuck makes bit changes fast on the job.

Who should buy it: Anyone already running 20V MAX batteries. The DCH273B uses the same batteries as your drill, impact driver, and circular saw — no new platform investment required.

• Impact energy: 2.1 joules
• Chuck: SDS-Plus
• Weight: 5.7 lbs bare
• Modes: Drill, hammer drill, hammer only

3. Milwaukee 2912-20 — Best for Milwaukee Users

The Milwaukee M18 FUEL SDS-Plus rotary hammer delivers 2.0 joules in the M18 FUEL package. Milwaukee's POWERSTATE brushless motor holds speed under load better than most competitors and the REDLINK PLUS intelligence prevents overload damage. The integrated ONE-KEY connectivity is a bonus for fleet management.

Who should buy it: Anyone already in the M18 ecosystem. At $249 bare it is the priciest of the three major cordless options but the build quality and motor performance justify the premium for heavy users.

• Impact energy: 2.0 joules
• Chuck: SDS-Plus
• Weight: 6.1 lbs bare
• Modes: Drill, hammer drill, hammer only

4. Makita HR2475 — Best Budget Corded Option

The Makita HR2475 delivers 2.7 joules from a 7-amp motor — more impact energy than any of the cordless options above at a fraction of the price. The trade-off is the cord, but for a shop, garage, or fixed work site that is rarely a problem. This is the tool to buy if you need SDS-Plus performance without the battery platform investment.

Who should buy it: Budget-conscious contractors, occasional users, and anyone who works primarily in one location where cord management is not an issue.

• Impact energy: 2.7 joules
• Chuck: SDS-Plus
• Power: 7 amps corded
• Weight: 5.5 lbs

5. Hilti TE 4-A22 — Best for Professional Fleets

Hilti tools cost more upfront but the service guarantee changes the math for professional contractors. If a Hilti tool breaks on the job they replace it — no waiting for warranty service. The TE 4-A22 delivers 1.7 joules on the 22V Nuron platform with Hilti's legendary build quality. For contractors running multiple tools daily the total cost of ownership often favors Hilti over a cheaper tool that needs replacement every 2-3 years.

Who should buy it: Professional contractors running tools daily who value service guarantee over upfront cost. Not for occasional users or homeowners.

• Impact energy: 1.7 joules
• Chuck: SDS-Plus
• Battery: 22V Nuron
• Service: Hilti Fleet Management available

What to Look For in a Rotary Hammer

• Impact energy (joules): The most important spec. 1.5-2.0J handles all residential anchor work. 2.0-3.5J for frequent large holes. Over 3.5J is SDS-Max territory for commercial work.
• Battery platform: Buy into the platform you already own. Cross-brand battery compatibility does not exist — pick one ecosystem and stay in it.
• Chuck type: SDS-Plus for holes up to 1-1/8". SDS-Max for larger holes and commercial work. The shanks are not interchangeable.
• Vibration control: Important for high-volume use. Active vibration control systems (Bosch AVS, DeWalt SHOCKS) make a real difference after 100+ holes per day.
• Hammer-only mode: Required for chiseling tile, breaking up thin concrete, and light demolition. All quality SDS hammers include this mode.
