TORQUE LIMITING
CLUTCH
These tools are equipped with a
torque limiting clutch that reduces
the maximum torque reaction
transmitted to the operator in
case of jamming of a drill bit. This
feature also prevents the gearing
and electric motor from stalling.
The torque limiting clutch has
been factory-set and cannot be
adjusted.
