The Milwaukee 1-3/4 in. SDS-Max Rotary Hammer has a powerful 15 Amp Motor capable of delivering 8.1 ft./lbs. of impact energy for the most demanding applications. The AUTOSTOP E-Clutch prevents over-rotation of the tool in case of tool lock up giving users a more controlled experience while using the corded rotary hammer drill. The variable speed dial allows users to set the optimal speed per application while 2 modes, Rotary Hammer and Hammer Only, allow easy transitions between drilling large holes or chipping applications. When chipping, a lock-on button allows users to chip without constantly pulling the trigger. Built-in Advanced AVS (Anti-Vibration System) minimizes the vibration users feel while using the rotary hammer drill. Includes a free 13 Amp 5 in. Small Angle Grinder With Dial Speed (6117-33D). The 13 Amp small angle grinder from Milwaukee maintains speed under load to power through tough jobs. Undeterred by industrial-grade materials, this 5 in. grinder spins up to 11,000 RPM with enhanced circuitry to prevent overloading or overheating.
