The Irwin Impact Pro Performance Screwdriver Bit Set is a comprehensive 10-piece collection engineered for high-torque applications and professional-grade performance. These bits are designed specifically for use with impact drivers, featuring a contoured geometry that allows the tip to flex under stress, effectively absorbing torque spikes to extend the tool's lifespan and prevent breakage. The full-fit head design ensures a secure connection with screw heads, significantly reducing wobble and eliminating the risk of cam-out or stripping. The set includes a robust, organised storage case for convenient access and protection of the bits during transport or storage. The kit contains four 25mm PH/TORX bits, four 25mm Pozi bits, and one bit holder.
