Irwin's Impact Performance Series bits are engineered for impact drivers, not merely compatible with them. Irwin rates them at three times the life of standard screwdriver bits. They are manufactured from heavy-duty, cold-forged, high-grade steel to withstand the high torque an impact driver produces, and a black oxide finish resists corrosion.

• Built for maximum durability and long life with impact drivers
• Precision tip geometry delivers superior fitment, reducing stripping and cam-out
• Heavy-duty, cold-forged, high-grade steel withstands high torque output
• Black oxide finish resists corrosion and increases bit life
• Three times longer life than standard screwdriver bits (Irwin rating)
• Phillips bits are forged rather than milled, so they fit the fastener recess more precisely
• Power Groove designed for compatibility with the Irwin Impact Performance Series Magnetic Screw-Hold Attachment
• 1/4" quick-change hex shank works with impact drivers and reduces slipping in standard drill chucks
• Tip: #2 Phillips
• Overall length: 2"
• Shank: 1/4" hex
• Sold as a 2-pack
• Manufacturer part: IWAF22PH22

Tip: Impact-rated bits matter most on long screws and hard fasteners, where an impact driver's hammering action is what breaks ordinary bits.
