Model HR2811F is a versatile, high-powered rotary hammer with an L-shape design ideal for horizontal work. The hammer accepts SDS-PLUS bits, and is powered by a 6.7 AMP variable speed motor delivering 2.7 Joules of impact energy. The HR2811F features 3-mode operation for “rotation only”, “hammering with rotation”, or “hammering only” for multiple applications, with 0-1,100 RPM and 0-4,500 BPM. The torque limiting clutch prevents gear damage by automatically disengaging gears if the bit binds. The HR2475 has an LED light for improved illumination of the work surface.
