This tool has been designed to provide professional contractors maximum performance, jobsite durability, and increased comfort. It has an 8 amp motor which provides high performance and overload protection: 0-1,150 RPM, 0-4,300 BPM. The variable speed trigger allows the user to instantly control speed from 0 to dialed setting, and delivers 2.5 ft lbs. of impact energy--all providing fast drilling and powerful chipping. A mode selector allows you to use this tool in three different settings: rotary hammer, rotary only, and chiseling applications. The additional reversing feature helps release tool from bind up situations, and assists with removal of fasteners. It has an integral clutch to reduce sudden, high torque reactions if the bit jams. It also features a 360-degree side handle that adjusts easily for preference or use in tight spaces. The dust extraction connection allows the use of the D25300DH dust collection system (sold separately).
