Lightweight and Class-leading Drilling and Demolishing performance*1

The lightest Rotary Hammer in its class (0.5 kg lighter than the current model*2) allows for increased maneuverability and less user fatigue.
Delivers powerful impact energy of 9.2J*3 for 17% faster drilling speed and 35% higher demolishing performance than the current model*2.

  1. As of July 1 2023, among 40mm class cordless rotary hammers made by leading power tool manufacturers. (Survey by Koki Holdings)
  2. Compared with HiKOKI DH36DMA.
  3. Impact energy according to EPTA-Procedure.

New Low Vibration Mechanism and Low Vibration Handle

  • 17% lower vibration than the current model*

    The new dynamic vibration absorber and low vibration handle significantly reduce vibrations for less user fatigue and improved operability.

    • Compared with HiKOKI DH36DMA.

Convenient Continuous Operation Function(only available for Hammering mode)

  • Continuous operation button keeps the tool operating even after the trigger switch is released, for less fatigue when chiseling for extended periods.

Bright LED Light

A high-brightness LED Illuminates the spot you are working on and turns off 10 seconds after releasing the trigger switch.

  • Reactive Force ControlAgainst Sudden Overburdening

    RFC logo

    When the tool bit is suddenly overburdened during operation, the slip clutch works or the built-in controller stops the motor output before the entire tool jerks.

    Depending on the operating conditions, the Reactive Force Control function may not work or provide the specified performance. Please make sure that the workpiece is placed and supported properly, and that the main unit is held firmly during operation.
