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

• 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) and demolition performance (up to 4.6kg / 5min.*3). 

*1: As of August 2016. Among 18V cordless rotary hammers made by leading power tool manufacturers (surveyed by Hitachi Koki).
*2: A comparison between the DH18DBDL (with the dust extractor system uninstalled) and the previous model DH18DSL (Actual performance results may vary depending on operating conditions.).
*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

High-Efficiency Particulate Air filter ensures clean air exhaust.

• Brush Cap

Brush cap and nozzle seal mounted to minimize the escape of dust.

• Drilling Depth Stop

adjustable up to 85mm 

Compatible drill bit
Diameter: 4.3-20mm
Effective length: 50-100mm

• 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. 

• 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)

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.

• Convenient Carrying Case

can store the hammer with the dust extraction system attached.
(The side handle has to be detached.)

• Quick-Release Tool Retainer

allows for fast change between the SDS-plus drill bit holder and the drill chuck holder (DH18DBML 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.

• 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.
 

* 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)

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.

Specifications
