When drill bit hits
against reinforcements,
Torque Limiter operates
to stop the rotation of
drill bit, ensuring safety
in your work.
No Hammering while
idling because air in the
cylinder is not compressed
unless tool is pressed
against ground.
This function ensures
machine's long life.
Provides more comfort and control
while minimizing hand fatigue and pain.
