Irwin Impact Performance Series insert bits are engineered for maximum durability when used with impact drivers. The precision-machined tip geometry delivers superior fitment to reduce stripping and cam-out.

• #1 Phillips drive tip for precision fastening
• 1" length insert bit with 1/4" hex shank
• Heavy-duty S2 tool steel construction
• Cold-forged for maximum strength and torque resistance
• Black oxide finish resists corrosion
• Optimized torsion zone absorbs impact torque

Tip: Impact bits are designed to withstand the high-torque, repetitive impacts of an impact driver. For best results, match the bit size to your fastener and use appropriate speed settings.
