Cordless Rotary Hammers with Dust Extractor System

Top-Class Capabilities
DH18DBDL / DH18DBML Cordless Rotary Hammers with Dust Extractor System

* As of August 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

Hitachi Original Brushless Motor Technology

  • ► No wearing parts (carbon brushes, commutator, field coil)
  • ► Hitachi original compact controller
  • Long Lifetime, 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.
  • Compact, Lightweight

*3: Actual performance results may vary according to the hardness of the concrete and other operational conditions.

Dust Extractor System

  • High-Efficiency Particulate Air (HEPA) Filter
Image of High-Efficiency HEPA Filter High-Efficiency Particulate Air filter ensures clean air exhaust.
  • Brush Cap

Compatible drill bit
Diameter: 4.3-20mm
Effective length: 50-100mm
  • Detachable Dust Box
Image to Detachable Dust Box allows easy dust disposal
  • Delayed Stop Function
The dust extractor system's internal motor stops after a delay of several seconds from when the tool's switch is released, so that it can vacuum remaining dust particles in the internal parts.
  • Cross Platform Compatibility
The dust extractor system included with the DH18DBDL fits on the DH18/36DBL. The one included with the DH18DBML fits on the DH18/36DBQL.
  • 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. Image of Improved handling
  • Top-Class Runtime *1
Number of 40mm deep holes drilled into concrete with a ø 8.5 drill bit
Up to 115 holes per charge with the dust extractor system
Up to 170 holes per charge without the dust extractor system

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


  • 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.

  • Quick-Release Tool Retainer
allows for fast change between the SDS-plus drill bit holder and the drill chuck holder (DH18DBML 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 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 status LED and sound alert once charging is complete
- USB port (5V 2A)
- Capable of charging at low temperature (-10ºC and above)

WARNING
CAUTION REGARDING LITHIUM-ION BATTERY TRANSPORTATION
