DH18DBL / DH18DBQL

Cordless Rotary Hammers

Top-Class Capabilities
DH18DBL / DH18DBQL Cordless Rotary Hammers

* As of April 2016. Among 18V cordless rotary hammers made by leading power tool manufacturers (surveyed by Hitachi Koki).

  • Lithium-ion Battery
  • Brushless Motor
  • SDS-plus Shank
  • Compatible Batteries
  • Reactive Force Control
  • More durability. Longer motor life. Maintenance-free.
Brushless MotorBrushless Motor 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
Drilling Speed: Up to 40% Faster, Demolition Performance: Up to 4.6kg / 5mins More 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 Hitachi Koki).
*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.
  • 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. Improved handling
  • Top-Class Runtime *1
Top-class Runtime : Up to 170 holes per charge Number of 40mm deep holes drilled into concrete with a ø 8.5 drill bit
18V: Up to 170 holes per charge

*1: As of April 2016. Among 18V cordless rotary hammers made by leading power tool manufactures (surveyed by Hitachi Koki).
*2: Included batteries vary by country or area.

  • Reactive Force Control(RFC)
Reactive Force Control 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
Caution
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. Convenient carrying case
  • 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
Multiple bit-angle settings The chisel can be rotated in multiple angles with the change lever positioned at 'neutral'.

  • Fast Charging offered by Hitachi's 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)

WARNING
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.
