Makita introduces the model HR4510C 1¾-inch rotary hammer with AVT technology, which is a counterbalance system engineered internally to reduce vibration. The hammer features dual-mode operation — hammering-with-rotation and hammering-only — with a built-in torque limiter that ensures stable torque control and disengages the motor should the bit bind or hit reinforcements. The 13.5-amp motor provides 130 to 280 rpm and 1,250 to 2,750 bpm for a range of applications. The unit weighs 18.3 pounds and has two options of side handles available (straight and D-shaped), both with rubberized grips.
