DEWALT 20V MAX SDS Rotary Hammer DCH273B – Bare Tool, 3 Modes, Lightweight

Powerful cordless performance for concrete and mounting projects

The DEWALT 20V MAX XR Brushless 1-inch SDS Rotary Hammer (DCH273B) brings cordless freedom to tough drilling and chiseling tasks. With a brushless motor and a German-engineered mechanism, it delivers 2.1 joules of impact energy for efficient concrete work, all packaged in a lightweight body designed to move with you from wall to wall, overhead to low reach. This combination helps you stay productive on busy job sites without being tethered to a cord.

Smart design that respects your workflow

Equipped with a rotating dial, you can switch between three modes—Drill, Hammer Drill, and Chip—so you’re ready to adapt as tasks evolve. SHOCKS ACTIVE VIBRATION CONTROL minimizes vibration at the handles, helping you maintain comfort and control during longer sessions. The tool’s brushless motor and durable German-engineered mechanism optimize efficiency and runtime, so you can accomplish more per battery charge while keeping a compact profile for tight spaces.

OSHA readiness and safety features

For workplaces that require dust extraction, this model can contribute to safer workflows when used with the DWH303DH On Board Extractor. The DCH273B becomes OSHA Table 1 compliant when paired with the extractor, a detail that can support on-site safety and compliance checks.

Versatility for professional mounting and installation tasks

The compact 1-inch rotary hammer is well suited for a range of mounting and installation tasks, including rod hanging, seismic and safety attachments, cable tray and strut mounting, clamp mounting, and rail mounting. Its cordless operation reduces setup time and makes overhead or awkward-angle work more manageable, letting you focus on precision rather than cords and extension leads.

• 2.1 joules of impact energy enable faster drilling in concrete and masonry.
• SHOCKS active vibration control reduces fatigue by dampening handle vibrations.
• Lightweight construction supports overhead work and constrained spaces with less user effort.
• Three application modes Drill, Hammer Drill, and Chip offer versatile on-site performance.
• Brushless motor and German engineered mechanism deliver efficient performance and longer runtime.
• OSHA Table 1 compliance is achievable with the DWH303DH extractor pairing.
