The Irwin 5 Piece Impact Screwdriver Bit Set is a professional-grade bit collection specifically engineered for use with high torque impact drivers. Designed to withstand the demanding conditions of regular site work, these bits are manufactured from heavy-duty, high-grade steel that delivers three times the lifespan of standard screwdriver bits.

This enhanced engagement is particularly valuable when working with stubborn or over-tightened fixings.
