Faithfull professional 1/4in Hex Drive Impact Screwdriver Bits are specifically designed to be used in high torque impact drivers. Made from a unique material that is engineered for outstanding durability, these bits have an increased working life in comparison to conventional screwdriver bits. Impact bits are designed to distribute impacts evenly, reducing energy waste for efficient screw driving. They incorporate torsion areas to absorb torque peaks and to minimise stress at the bit tip during heavy loading. All bits have a precision-machined tip to provide an optimum fit, helping to minimise screw stripping and cam-out.
