  • HIGH IMPACT: The impact driver is among the most popular cordless power tools today for driving screws and other fastening tasks. From breaking loose a stuck nut to driving screws and fasteners into hard materials like metal, the Hi-Spec 44 Piece 1/4” Hex Shank Impact Driver Screw Bits Set is specifically designed for the rigours of use with an impact driver, withstanding its high torque and concussive effects for extended periods of time
  • METAL TO METAL IMPACT: The Hi-Spec 44 Piece 1/4” Hex Shank Impact Driver Bits are designed and rated to outperform standard bits when the maximum torque of the impact driver is applied – high torque that snaps normal bits on the first try. Metal to metal fastening needs high torque to break the friction between the metals. High torque is delivered to tighten down fasteners in hard-stop fastening. And high torque is applied to pound nut drivers turning long lag-bolts
  • DESIGNED FOR IMPACT: For DIY jobs that maximise an impact driver’s torque potential, make room in the tool box for the Hi-Spec 43 Piece 1/4” Hex Shank Impact Driver Bits Set. Their precision machined tips fit for full fastener contact, reducing stripping and cam-out. An extended torsion zone in the bit’s shank distributes the excessive stress away from the tip into a greater area giving durability and longer life as compared to standard bits with their weakest points at the tip or shaft
  • TIME TO IMPACT: Made from heat treated S2 Shock-resisting steel, the addition of silicon gives increased tempered hardness, with Rockwell C Hardness of 60, as compared to ordinary Cr-V. Ductility gives the ability to twist and flex under the high torque and concussive effects of impact drivers. A manganese phosphate coating gives improved corrosion and wear resistance whilst retaining the light oil protective coating. 6.35mm / 1/4" hex shanks enable quick change out and no slipping in chucks
