DeWalt DCH773N 54v XR FLEXVOLT SDS-Max Rotary Hammer Drill Body Only in Carry Case The Dewalt DCH773 SDS-Max Rotary Hammer Drill is perfect for chipping and bushing. It features a 54v brushless motor similar to that of a corded machine for increased run time and performance. High-speed drilling ensures the fast and efficient completion of jobs. It is extremely user-friendly thanks to its anti-rotation system which detects a loss of tool control and reacts by instantly cutting the power and active vibration control which reduces vibration for maximum comfort and reduced fatigue. FEATURES True corded performance An anti-rotation system detects a loss of tool control and reacts by instantly cutting the power Active vibration control system incorporating a floating handle delivers extremely low vibration Rotation-stop for demolition applications in brick, masonry and light chasing in concrete Perform & Protect: low vibration at 10.1m/s², minimising user fatigue Brushless motor for extreme run time, increased performance and reduced maintenance Electronic speed and impact energy control Ideal for drilling anchor fixing and through holes in concrete and masonry from 12 to 52 mm in diameter Core drilling up to 150 mm 2 modes - rotary hammer only and rotary stop Anti-Rotation and service indicators Patented Low vibration side handle reduces fatigue and increases safety, comfort and productivity SPECIFICATION Battery Capacity: 12.0Ah @ 18v / 4.0Ah @ 54v Impact Energy: 19.4 J Chuck Type: SDS MAX Fitting Blows Per Minute: 1105-2210 bpm No Load Speed: 145-290 rpm Drilling Capacity Concrete Ø: 52 mm Drilling Capacity Core Bit Ø: 150 mm Tool Weight with Battery: 10.1 kg NOISE & VIBRATION Sound Pressure: 96 dB(A) Sound Pressure Uncertainty: 3 dB (A) Sound Power: 107 dB(A) Sound Power Uncertainty: 3 dB(A) Uncertainty K 1 (Vibration): 1.5 m/s² Hand/Arm Vibration Hammer Drilling into Concrete: 10.1 m/s² Hand/Arm Vibration Chiselling: 9.4 m/s²
