Cordless Rotary Hammers DH18DBL / DH18DBQL

  • DH18DBL Cordless Rotary Hammers


  • DH18DBQL Cordless Rotary Hammers



More durability. Longer motor life. Maintenance-free.

  • The brushless motor offers a significantly extended product life cycle by eliminating trouble including armature burnout, layer short or commutator wear even in severe work environments. Besides, no carbon brush replacement is required.

Top-Class *1 Capabilities

  • The highly efficient brushless motor and the optimized hammering mechanism achieves the top-class*1 drilling speed (up to 40% faster *2,3) and demolition performance (up to 4.6kg / 5min.*3).

    1. As of April 2016. Among 18V cordless rotary hammers made by leading power tool manufacturers (surveyed by Koki Holdings.)
    2. A comparison between DH18DBL/DH18DBQL and the previous model DH18DSL.
    3. The actual value may vary according to the hardness of the concrete and other operational conditions.
    Drilling Speed: Up to 40% Faster, Demolition Performance: Up to 4.6kg / 5mins More

Improved Handling

Pic.1: The grip of the handle and the drill bit head are on the same line of action, which makes applying force to the drill easier.
Pic.2: The grip of the handle is close to the center of gravity for easier handling.

Top-Class Runtime *1

  • Number of 40mm deep holes drilled into concrete with a ø 8.5 drill bit
    18V: Up to 170 holes per charge

Reactive Force Control(RFC)

  • Reactive Force Control Logo

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

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

Convenient Carrying Case

  • The rotary hammer can be stored in the case with the side handle attached.

Quick-Release Tool Retainer

allows for fast change between the SDS-plus drill bit holder and the drill chuck holder (DH18DBQL only).

Quick-release tool retainer

Note : Turn the change lever to "Hammering only" mode when replacing a tool retainer with another.
Use the machine only in "Rotation only" mode when the drill chuck holder installed.

Multiple Bit-Angle Settings

  • The chisel can be rotated in multiple angles with the change lever positioned at 'neutral'.

Fast Charging offered by Our original charging technology

Built-in cooling system of the UC18YSL3 charger drastically reduces charging time by efficiently cooling both the battery and charger at the same time during charging.

Charging time is 6.0Ah Approx. 38mins, 5.0Ah Approx. 32mins.
  • Included batteries vary by country or area.

Other features of the UC18YSL3 charger

- Large charge indicator lamp with 4 color LED status lights
- USB port (5V 2A)
- Low-temperature charge (-10º and above)


Notify the transporting company that a package contains a lithium-ion battery, inform the company of its power output and follow the instructions of the transportation company when arranging transport.

  • Lithium-ion batteries that exceed a power output of 100Wh are considered to be in the freight classification of Dangerous Goods and will require special application procedures.
  • For transportation abroad, you must comply with international law and the rules and regulations of the destination country.
