Onpin OP-14AKS Pneumatic Air Tapper B16 Spindle - Overload Protection, 3-12mm, 350RPM
The Onpin OP-14AKS pneumatic air tapper features a robust gear-type structure, a 44 mm shank diameter, and a low-runout B16 taper spindle for high-precision operations. Operating at a free speed of 350 RPM with air consumption of 283 l/min, it delivers a versatile 3~12mm tapping capacity across aluminum, copper, and iron. Equipped with an international-standard three-jaw clamping chuck, it incorporates internal overload protection that automatically slips under torque overload to prevent tap breakage and protect workpieces during blind hole tapping. Designed with a push-button forward/reverse switch for fast one-handed operation and compatibility with the RB16 support arm, it is highly suitable for machinery, machine tools, mold processing, and automotive/motorcycle parts industries.
