DEWALT DCH273B 20V MAX* XR® Brushless 1” L-Shape SDS Plus Rotary Hammer

Corded Power Without the Cord: The Industry Standard for Balanced, High-Performance Drilling.

Engineered for the professional who spends their day drilling into concrete and masonry, the DEWALT DCH273B delivers the perfect blend of power and protection. Powered by a high-output XR® Brushless motor, this 1-inch rotary hammer produces an impressive 2.1 Joules of impact energy, allowing you to fly through anchoring tasks with the speed of a corded tool.

The L-Shape design provides superior balance, making it the ideal choice for overhead drilling in commercial construction, plumbing, and electrical installations.

Why the DEWALT DCH273B is the Professional’s Choice:

• 2.1 Joules of Impact Energy: Experience high-speed drilling that rivals corded units. This tool is optimized for 1/4" to 5/8" diameter holes but handles up to 1-inch bits with ease.
• SHOCKS™ Active Vibration Control: Protect your hands and arms. This integrated system reduces vibration felt at the handles, significantly lowering user fatigue and increasing productivity during long shifts.
• Efficient Brushless Motor: DEWALT’s XR® technology maximizes battery runtime and motor life, ensuring you get more holes per charge than traditional brushed motors.
• OSHA Table 1 Compliant Ready: Pair this tool with the D25303DH integrated dust extractor (sold separately) for a cordless, dust-free solution that meets strict safety regulations.
• Factory-Set Clutch: Reduces sudden, high-torque reactions if the bit jams, providing an extra layer of safety for the operator.
• Retractable Utility Hook: Easily hang the tool on a ladder, lift, or scaffolding when not in use, keeping it secure and within reach.
