This demolition hammer applies impact force to the bit to chisel concrete and other materials. By digitally analyzing optimum impact timing, the hammering capability of this product has been increased by 47% compared to conventional models. User fatigue has been further reduced by attaching the handle to the housing with a rubber and by significantly reducing vibration (54%) with Hitachi’s low vibration mechanism using a tip damper and air cushion structure. In addition, the motor housing features a dual structure of highly rigid aluminum and plastic for enhanced durability.
