18V Cordless Rotary Hammer DH18DPA

  • 18V Cordless Rotary Hammer:DH18DPA
  • 18VLi-ion battery

  • Brushless Motor
  • Low Vibration Handle
  • Reactive Force Control
  • SDS Plus Shank

Compact, Lightweight, and Well-balanced

  • Users feel less fatigue due to the compact, lightweight and well-balanced design with most of the weight positioned close to the hand.

    • With BSL1850C Battery (inc. Side Handle)
    Length from the hand to the tip is 231 mm, and weight is 2.3 kg.

Class-Leading*1 Drilling Speed

  • The DH18DPA is suited for drilling small holes into concrete, completing the job faster than corded counterparts.

    2. The values are shown for reference purposes and may vary according to materials and conditions.
    Drilling speed of DH18DPA is about 23% faster than our conventional model.

Low VibrationLow Vibration Handle (LVH)

  • The low vibration handle provides rubber handle dampers to absorb vibrations and shocks during operation.

    Triax Vector Sum (m/s2)

    Vibration Value Comparisone of DH18DPA is 9.9m/s2, which is about 18% lower vibration than 12.1m/s2 of our conventional model DH18DSL.

2-step Rotation Speed for Different Applications

  • Makes it easy to drill a fragile material by pressing the changeover switch to reduce the rotation speed and impact rate.

Built-in Auto Stop Function for Consistently Drilling Holes

  • Once the initial drilling time is recorded on the tool, the motor is designed to automatically stop when the recorded time has passed, enabling a stable and efficient continuous operation.

    Image of the case
The auto stop function is used to record the drilling time. Thus, it may not provide the same drilling depth owing to the operator position, pushing force, and variation among the workpieces. Please use a depth gauge to ensure the drilling depth.

Reactive Force Control(RFC)Against Sudden Overburdening

  • 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.

    RFC explanatory illustration
    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.
