Milwaukee 1-3/4" SDS Max Rotary Hammer has a powerful 15A 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 you a more controlled experience while using the corded rotary hammer drill. The variable speed dial allows you to set the optimal speed per application while two modes, rotary hammer and hammer only, allow you to easily switch between drilling large holes or do chipping applications. When chipping, a lock-on button allows you to chip without constantly pulling the trigger. Built-in Advanced AVS (Anti-Vibration System) minimizes the vibration you feel while using the rotary hammer drill. Includes: side handle and grease tube.
