The DEWALT DCH273H1 20V MAX XR Brushless 1 in. Cordless Rotary Hammer is built for fast drilling in concrete and masonry. Its brushless motor and durable German-engineered mechanism deliver 2.1 joules of impact energy while keeping the tool lighter and more comfortable during overhead work. As part of DEWALT's PERFORM AND PROTECT™ lineup, this rotary hammer helps you work cleaner and safer on the job.
DEWALT DCH273H1 Rotary Hammer Performance and Control
The DCH273H1 uses SHOCKS ACTIVE VIBRATION CONTROL to reduce vibration at the handles, which means less fatigue when you're drilling overhead or making long runs. With 2.1 J of impact energy, this cordless rotary hammer drills through concrete, brick, and block quickly without a cord.
OSHA Table 1 Compliant Setup with DEWALT DWH303DH Extractor
When performance and protection matter, pair the DCH273H1 with the DWH303DH on-board dust extractor. This setup meets OSHA Table 1 silica dust compliance, keeping your work area cleaner and reducing exposure. Here’s how to attach the dust extractor:
- Slide the DWH303DH extractor onto the DCH273H1’s accessory rail until it clicks into place.
- Make sure the extractor sleeve fits snugly over the drill bit before starting.
- Connect the extractor hose to a compatible DEWALT vacuum or dust collection system.
- Use the onboard controls to start/stop dust collection as needed.
Always verify that the extractor is fully seated and the filter is clean for best dust capture performance.
What's in the Box
This kit includes the DEWALT DCH273H1 rotary hammer, one 20V MAX 5.0 Ah battery, charger, side handle, and a heavy-duty kit bag. It's ready to work out of the box for concrete anchors, rod hanging, cable tray mounting, and seismic attachments.
Choosing the Right Rotary Hammer
The 1-inch chuck capacity suits most anchor and through-hole drilling in concrete. If you need larger holes, step up to a spline-drive or SDS-Max model. The DCH273H1 uses SDS-Plus bits for quick bit changes and efficient power transfer.
