Ergonomic inline design lets you dig and hammer more comfortably. The Milwaukee 14 Amp 2" SDS-Max Demolition Hammer (5339-21) delivers 19.9 ft-lbs of blow energy for hammering large holes in concrete or asphalt, bushing, driving ground rods, scraping floors, digging and tamping. The inline design offers more comfortable operation, and the soft-grip side handle can be attached to the rear switch handle to minimize bending. Milwaukee’s unique Anti-Vibration System provides added comfort by minimizing vibration. Sophisticated electronic feedback offers consistent operation and overload protection. This robust electric hammer features a variable-speed dial for optimum control, a service-reminder light and easy access for maintenance. You can position chisels more efficiently with the SDS-max bit holder system. The tool uses standard SDS-max hammer iron, and comes with two auxiliary handles and a carrying case.
