- 2.1 Joules of impact energy for fast drilling in concrete with a cordless hammer drill. - SHOCKS Active Vibration Control System reduces the vibration felt at the handles, compared to rotary hammers without this feature. - Lightweight design makes this 20V brushless hammer drill easy to handle for rod hanging, seismic and safety attachments, cable tray and strut mounting, clamp mounting, and rail mounting. - OSHA Table 1 compliant when paired with the DWH303DH On Board Extractor. - Brushless motor and durable German engineered mechanism deliver efficient performance and extended runtime. Use scenarios - Installing cable trays and struts in electrical or mechanical installations where a light, low vibration tool improves control and reduces operator fatigue. - Mounting rods, clamps, and seismic or safety attachments to structural frames or support structures, leveraging the compact form and ease of use. - Drilling into concrete for anchor bolts and fasteners during renovations or new construction projects, benefiting from the 2.1 J impact energy and efficient brushless motor.
