Core Performance & Features The DeWalt DCH273B is powered by a brushless motor and a German-engineered mechanism that delivers 2.1 Joules of impact energy for drilling 24mm diameter holes in concrete. This cordless rotary hammer features a 3-mode rotating dial, allowing switching between Rotary Only for wood/metal, Hammer Drill for concrete/masonry, and Chip Only for light chiseling in plaster and tile. The SHOCKS Active Vibration Control system significantly reduces vibration felt at the handles, a key feature of the Perform and Protect lineup, which minimizes user fatigue during extended use. An electronic clutch improves torque consistency and tool durability. The tool is OSHA Table 1 compliant when paired with the optional onboard dust extractor. A bright white LED with delay function improves visibility in dark workspaces. Battery and charger sold separately.

Target Audience & Use Cases Professional contractors, electricians, plumbers, masons, and serious DIY users. Ideal for drilling anchor and fixing holes in concrete, brick, and masonry (4-24mm diameter), including rod hanging, seismic and safety attachments, cable tray and strut mounting, as well as light chiseling tasks like tile or mortar removal.

Runtime & Compatibility This bare tool is compatible with all DeWalt 20V MAX batteries (sold separately). For optimal performance on demanding drilling and chipping applications, pairing with high-capacity XR 4.0-5.0Ah batteries is recommended, as smaller packs (2-3Ah) may result in shorter runtime. The efficient brushless motor maximizes runtime per charge.

Ideal Customer Profile Professional tradespeople who frequently anchor into concrete and require a cordless solution to replace a corded SDS-Plus drill. Users value the combination of light weight (approx. 6.8 lbs), active vibration control for comfort, and the versatility of a 3-mode rotary hammer. This is ideal for those already invested in the DeWalt 20V MAX platform seeking a dedicated tool for medium-duty concrete work and light demolition.

Final Summary The DeWalt DCH273B combines 2.1 J of impact energy with 3-mode versatility and active vibration control. It delivers professional-grade performance for concrete drilling and light chipping tasks, making it a reliable choice for tradespeople who need to work efficiently on construction sites or in home improvement projects.
