PTA Impact bits are built tough, featuring an oversize torsion zone to reduce breakage and extend lifetime. 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 a superior fastener adhesion. It all adds up to a bit that’s design, delivering on the promise of ultimate bit life. 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 This accessory is manufactured from S2 steel, machined and heat treated Magnetic Lobular Head: Subtle cam in-hex design applies driving force to the flat surface of the fastener, preventing damage to its corners and a reduction in potential round-off Magnetic Quick Release: Quick release coupler provides quick change overs of 25mm driver bits Simply push the knurled grip forward to eject the bit (Fits all other 1/4"driver bit lengths) Magnetic Extreme C-Clip Coupler: Impact rated for high torque applications, driver bit is retained with a magnet and our EXTREME strength C-Clip Our coupler has been designed so the driver bit will NOT eject free when in use Socket Driver Adaptor: Available in 1/4", 3/8"and 1/2" drive, the socket driver adapts a socket onto your 1/4" impact driver or standard drill driver *Driver bit is NOT removable by hand, pliers will need to be used to remove the bit. For regular bit changes, use the Kincrome Quick Release Coupler *If using an impact driver, you MUST use an impact rated socket. Specifications Part Number K21003 Brand Kincrome Item Type Driver Bit
