A pneumatic piston powers the striker that transfers impact to the bit. parkerhydraulicpumps This design reduces operator parkerhydraulicpumps fatigue and makes drilling more efficient. Unlike the more versatile parkerhydraulicpumps hammer drill, though, a rotary hammer parkerhydraulicpumps can''t be used for drilling wood or metal.
