Onpin OP-08AKS Pneumatic Air Tapper B12 Spindle - Overload Protection, 3-8mm, 350RPM

Specification OP-08AKS

The Onpin OP-08AKS Air Tapper is an industrial pneumatic tapping tool powered by compressed air at a standard operating pressure of 90 psi (6.2 bar) for internal thread cutting on metal workpieces. Engineered with a heavy-duty gear-type structure and a low-runout B12 taper spindle, it delivers high precision at a free speed of 350 RPM. The tool features an integrated internal overload protection mechanism within the chuck that automatically slips under torque overload to safeguard taps and workpieces.
