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).
As of April 2016. Among 18V cordless rotary hammers made by leading power tool manufacturers (surveyed by Koki Holdings.)
A comparison between DH18DBL/DH18DBQL and the previous model DH18DSL.
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.
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
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).
Multiple Bit-Angle Settings
The chisel can be rotated in multiple angles with the change lever positioned at 'neutral'.
