Easy-to-operate and double-molded switch handle and side handle
The base material of the switch handle and the side handle is plastic resin. The plastic resin base is
integrally molded with soft resin to realize a double layer structure. Thus the grip of the switch handle and
the side handle is soft for easier operation.
Change lever for switching between "Rotation + Hammering,"
"Neutral" and "Hammering only"
The Models DH 50MRY/DH 50MR provides three
functions, "rotation + hammering" function (for drilling),
"neutral" function (for positioning the tool tip) and
"hammering only" function (for chiseling and chipping).
These function modes can be easily switched by using the
change lever. The tool angle can be easily changed in 12
steps by turning the grip with the change lever positioned
at "Neutral."
Needle-pin type slip clutch
The Model DH 50MRY/DH 50MR is equipped with a needle-pin type slip clutch for higher slip torque
accuracy and enhanced safety (same as the Model DH 50MB).
