• The product life cycle is significantly extended by eliminating troubles with armature burnout, layer short and commutator wear. Besides, no carbon brush replacement is required.

  

The efficient brushless motor offers higher drilling performance even with an extension cord used.

Designed to be powered by engine generators as well, thanks to Our original compact and high efficiency inverter circuit.

• As of March 2015. Among 45mm class rotary hammers made by leading power tool manufacturers, surveyed by Koki Holdings.

• reduces the vibration from concrete drilling or chiseling by moving a weight and a leaf spring in the opposite direction to the movement of the hammer.

  

provides high vibration-absorbing effect by employing both transatory and hinge units.

• makes the housing more rigid, significantly enhancing durability of the motor unit.

  

• 

  1. Push-button, constant speed control with variable speed
  Due to the 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.
