Finished in black phosphate for additional corrosion protection, PTA Impact bits also provide a precision fit to help prevent stripping and reduce cam-out, the result is superior fastener adhesion. It all adds up to a bit that’s better by design, delivering on the promise of ultimate bit life. Features Torsion Control zone - Absorbs extreme torque loads to optimise control whilst preventing fastener cam-out, extending the lifetime of your impact bit. Magnetic Precision Tip - CNC machined tips offer a precise fit to prevent stripping and fastener cam-out, magnetised for ultimate control Impact Performance - PTA is uniquely designed for extreme impact and torque applications.
