Lowest Vibration in its Class*1

  • A dynamic damper containing a leaf spring and a weight absorbs vibration by resonating with the tool body.

    Absorb vibration by resonance

    Vibration Value Comparison (approx.)*2

    The vibration value of DH28PCY2/DH28PBY2 with UVP(User Vibration Protection) is reduced by approx 24% compared to the existing model DH28PC/PB without UVP(User Vibration Protection).
    1. As of July 2019. Among 28mm rotary hammers excluding the DH28PEC made by leading power tool manufacturers. (Survey by Koki Holdings)
    2. Vs. the existing model DH26PC/PB. The values are shown for reference purposes and may vary according to materials and conditions.

Compact Body

  • The shortened overall length results in better handling.

    • Vs. the existing model DH28PCY/PBY.
    Compared to the existing models DH28PCY/PBY, the total length is 7mm shorter.

New Construction for Motor Protection Labyrinth Ventilation Windows for reducing the ingress of dust and debris into the tool

  • Double ventilation windows (inlets) in labyrinth construction does less harm to the motor by reducing the ingress of dust and debris into the tool.
