The Milwaukee 1-1/8-Inch SDS Drive L-shaped Rotary Hammer is a 3-mode rotary hammer great for mid-size hole drilling (up to 1-1/8-inch diameter) in concrete. The hammer sports a D-style rear handle that offers a secure and comfortable grip and an easily accessible two-finger speed control trigger switch. Speed control allows smooth controlled starts and less bit walk for accurate hole positioning. The hammer accepts SDS style bits up to 1-1/8-inch diameter, and can drill up to 3-1/2-inch holes in concrete using thin-wall core bits. An included hammer-only mode allows the tool to be used for light chipping work, and the on-board slip clutch protects the mechanism from overload by stopping rotary action when a bit jams. This 7.4 Amp tool can be set to a rotation-only mode for drilling in steel or wood, and a 3-jaw chuck adapter kit is also available (sold separately). This rotary hammer is backed by a 5-year limited warranty.
