1-9/16" SDS-MAX Rotary Hammer with AVT Technology

Makita has adapted the science of earthquake engineering into power tools with Makita's Anti-Vibration Technology (AVT). AVT is an exclusive innovative counterbalance design that provides the professional a power tool solution with up to 3X less vibration, less noise and more efficient power than the competition. Seismic research has developed this damping science over years to absorb the shocks and protect buildings from devastation of earthquake vibrations.
The 1-9/16" SDS-Max Rotary Hammer, model HR4010C features AVT Technology with 2X less vibration at only 4.5 m/s² plus producing 2,750 blows per minute. Model HR4011C produces an impressive 11 AMPS with 7.0 ft.lbs. of impact energy and has synchronized RPM and BPM to prevent overlapping impacts for up to 50% more efficient drilling. A variable speed dial with 5 different preset speeds and electronic speed control minimizes speed loss for 28% faster drilling.
