Irwin 1837456 Phillips #2 Impact Power Bit, 1/4" Shank

Irwin 1837456 Phillips #2 Impact Power Bit, 1/4" Shank

The Irwin Phillips #2 Impact Power Bit is engineered specifically for impact drivers, delivering the fastener-driving performance today's cordless tools demand. This 1/4" quick-change bit features a shank designed to work seamlessly with impact drivers while also reducing slipping when chucked into a standard drill. Manufactured from cold-forged, high-grade steel rather than simply milled, the bit is built to withstand the extremely high torque output generated by impact drivers without stripping or breaking down. A black oxide finish resists corrosion and extends the working life of the bit, making it a dependable choice for professional and DIY fastening projects alike.

Key Features

• Quick-Change Shank: The 1/4" quick-change shank is designed to work with impact drivers and also reduces slipping when used in standard drill chucks, giving installers flexibility across tool types.
• Power Groove Compatibility: A Power Groove is engineered into the bit for compatibility with the Irwin Impact Performance Series™ Magnetic Screw-Hold Attachment, helping keep fasteners aligned during one-handed driving.
• Precision Tip Geometry: The Phillips #2 point delivers superior fitment inside the fastener head, reducing stripping and cam-out for cleaner, more consistent drives.
• Forged, Not Milled: Unlike many screwdriving bits that are simply compatible with impact drivers, this bit is forged rather than milled, so it fits fasteners more precisely and delivers up to three times longer life than traditional bits.
• Durable Steel Construction: Manufactured from heavy-duty, cold-forged, high-grade steel, the bit is engineered to withstand extremely high torque output without deforming or breaking.
• Corrosion-Resistant Finish: A black oxide finish resists corrosion and increases the overall service life of the bit in demanding jobsite conditions.
• Built for Impact Drivers: Designed and engineered for maximum durability with impact drivers, not just compatible with them, for long-term reliable performance.

Why Irwin?

Irwin Impact Performance Series™ bits are purpose-built for impact drivers rather than simply rated as compatible with them. By forging the bit from heavy-duty, cold-forged, high-grade steel instead of milling it, Irwin achieves tighter fastener fitment, reduced stripping and cam-out, and a working life up to three times longer than traditional bits. The black oxide finish adds corrosion resistance, helping this Phillips #2 power bit stand up to demanding jobsite conditions while delivering the precision and durability professionals expect from Irwin tools.
