Chiseling performance varies considerably depending on the work conditions. Use the factory
test results for comparison purposes only.
Refer to the Technical Data and Service Manual of the current Model DH 50MB for the following.
Vibration-absorbing handle
The two vibration-isolating rubbers provided between the
handle and the crank case, and also between the handle and
the housing efficiently absorb the vibration transmitted from the
tool main body to minimize transmission of vibration to the
operator's arms.
Dial type, constant speed with variable speed control
The Model DH 50MRY/DH 50MR is equipped with a built-in
electronic control circuit that can adjust the number of hammering
steplessly between 1,050 and 2,150 min
the load varies, the Model DH 50MRY/DH 50MR provides better
operability and stable and efficient drilling performance because the
constant speed control minimizes changes in number of rotation and
hammering.
