The Bosch 11240 is a Factory Reconditioned 1-9/16 inch 2-Mode SDS Max Combination Hammer. The hammer features a 10 Amp motor, dual-mode selector lever for hammering with or without rotation and Vario-Lock positioning that rotates and locks the chisel into 12 different positions. The SDS-Max system facilitates tool-free bit changes with automatic bit locking, dust protection and a maximum-impact energy transfer rate. The tool includes such extras as innovative service modules designed so a qualified service technician can quickly replace the brushes and cord, a 360º auxiliary handle and an integral clutch (to minimize torque reaction).
