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.

• 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).

  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.

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.

 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.

Caution

Depending on operating conditions, Reactive Force Control 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.

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

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

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.

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

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.

• Included batteries vary by country or area.

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

CAUTION
REGARDING LITHIUM-ION BATTERY
TRANSPORTATION

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.
