Reversible pneumatic impact wrenches with torque control and automatic air shut-off, indispensable where very high torque repeatability is required both in the presence of rigid and elastic joints. The tightening torque is adjusted by varying the compression of the main clutch spring, by screwing or unscrewing the threaded adjustment ring with a screwdriver (supplied). The machines do not have a torque reading scale, any verification of the preset torque must be performed with a dynamometric instrument (not supplied). The standard equipment includes a complementary spring for the clutch. Features: Straight handle with push start Supply: Non-lubricated and lubricated compressed air - Recommended pressure 6.3 Bar
