The SDS-plus 1 1/8" Rotary Hammer can deliver 2.4 ft.-lbs of impact energy, but this tool weighs only 7.7 lbs and is a compact length of 12.5", for an outstanding power-to-size ratio. The 8.0-amp motor generates up to 4,000 blows per minute, making it an ideal choice for construction or demolition. The multifunction selector gives the user the versatility to match mode to application, rotary hammer, rotation-only or hammer-only mode. It has Vibration Control in the hammer mechanism and grip area to provide improved user comfort. The hammer provides an integral clutch that discontinues power transmission for bind situations, and it has Vario-Lock to set the chisel into one of 12 positions for better leverage.
