  • Hitachi's original, spring-type dynamic vibration absorber
Hitachi's original, spring-type dynamic vibration absorver with a weight and two springs moves in the opposite direction to the vibration direction of the main body. This results in reduced vibration and improved operating efficiency. 
  • Vibration-absorbing handle
Vibration-absorbing mechanism with the transatory unit and the Neidhardt spring provides high vibration-absorbing effect.
  • The internal double-insulation construction with a very sturdy aluminium die-cast body and a plastic internal stator holder, is incorporated.
This makes the housing more rigid, significantly enhancing durability of the motor unit.
  • Push-button, constant speed control with variable speed
Equipped with a built-in electronic control circuit that can adjust the impact rate according to applications. Four-step impact rates can be selected by the rotation speed selector switch.
