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. 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 25 mm 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. NOTE: 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; 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.
