40mm (1-9/16") Rotary Hammer
Approx. 13% Faster Drilling Speed
Approx. 28% More Demolition Performance
*1: A comparison between the DH40MC and previous model DH40MR. (When drilling ø16-40mm holes into concrete. Actual results vary depending on conditions.)

A larger damper and higher volume air cushion reduce the impact and piston reaction force generated during hammering. This results in significant vibration reduction.

It only takes one action instead of conventionally-required two to mount a drill bit. All that needs to be done is insert the drill bit into the tool holder while turning it.
Large change lever located on top of the tool for easy visibility allows smooth mode changing.
- Hammering (for demolition)
- Neutral (for bit angle adjustment)
- Rotation + Hammering (for drilling)
- Multiple Bit-Angle Settings
The chisel can be rotated at 12 different angles with the change lever positioned at 'neutral'.
Large trigger switch is easy to grip and fit the hand for more control with less fatigue.
