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.
Makita rotary hammers are engineered with the Makita Motor Advantage, which features field core interlocking steel laminations, dual ball bearing armature, and more copper commutator bars. These engineering points-of-difference increase the energy transfer efficiency for more power and longer tool life.
