Torque Control Impactools are designed for applications requiring fastener tightening control. The tools shut off automatically when preset torque levels are reached. Depending upon the model, built-in or detachable torsion bars sense torque levels, and signal a mechanical shut-off device to prevent over-torquing. These tools combine a ball and cam impact mechanism with a heavy-walled aluminum hammer case for maximum strength, minimum weight.

Features:
* Planetary gear drive delivers smooth constant speed from motor.
* High strength aluminum alloy hammer case protect internal impact mechanism parts
* Calibrated location collar holds torsion bar in preloaded condition
* Adjustable torsion bar signals shutoff device when preset torque is reached
* Tough Steel anvil transfers blows from impact hammer to the fastener
* Ball and cam mechanism converts air motor torque into powerful rotary impacts
* Models ending in L1 are equipped with light torsion bar Models ending in M1 are equipped with medium torsion bar Models ending in H1 are equipped with heavy torsion bar
* ¼” NPT air inlet
* Square Drive impact with pin-type retainer
