Driven by a robust 8.5 Amp motor, this rotary hammer delivers a formidable 2.4 Ft.-Lbs. of impact energy and up to 5,100 BPM, ensuring rapid progress through concrete and masonry. Designed for the hardworking professional, it features Bosch-exclusive KickBack Control—an integrated sensor that instantly stops tool rotation during bit bind-up situations to protect the user from sudden torque reactions. Whether you are a masonry pro or a general contractor, this tool provides the perfect balance of raw power and intelligent safety.\u003c\/p\u003e\n\u003cp\u003eComfort and versatility are at the core of the GBH2-28L-RT design.
