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.

Technical Specifications

  • Point Size: #2
  • Shank Diameter: 1/4"
  • Shank Type: 1/4" Quick-Change
  • Bit Configuration: Single-piece Phillips power bit

Typical Applications

  • Driving Phillips-head fasteners with impact drivers on jobsites and in the shop
  • Construction, remodeling, cabinetry, and general assembly projects requiring repeated fastening
  • High-torque, repetitive fastening tasks where bit longevity matters
  • Pairing with the Irwin Impact Performance Series™ Magnetic Screw-Hold Attachment for one-handed fastener starts
  • Professional trade use as well as DIY home improvement projects

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.

Irwin 1837456 – Frequently Asked Questions

1) Will the Irwin 1837456 Phillips #2 bit fit my impact driver's quick-change chuck?
Yes. The 1837456 has a 1/4 inch quick-change shank, which is the standard collet size on cordless impact drivers, so it drops straight into the chuck. The same shank also works in a standard drill chuck, and Irwin shapes it to reduce slipping when it is gripped by three jaws instead of a collet.
2) Can I use a regular screwdriver bit in an impact driver instead of this one?
You can, but standard bits are milled and tend to deform or snap under the hammering torque an impact driver puts out. The Irwin Impact Performance Series bit is cold-forged from high-grade steel specifically for that duty cycle, and Irwin rates it at up to three times the life of a traditional bit. If you are driving repetitive Phillips fasteners all day with an impact, the forged bit is the one to use.
3) Does this Irwin power bit work with the magnetic screw-hold attachment?
It does. The bit is machined with a Power Groove so it locks into the Irwin Impact Performance Series Magnetic Screw-Hold Attachment, which holds the fastener aligned on the tip for one-handed starts overhead or in a tight bay. The sleeve is a separate purchase, not included with the bit.
4) What is a Phillips #2 bit used for, and how do I know my screws take it?
Phillips #2 is the point size that fits the great majority of construction and cabinet screws, drywall screws, and general assembly fasteners. The 1837456 is a single-piece Phillips power bit with a #2 point, and Irwin forges the tip for a tighter fit inside the recess, which cuts cam-out and stripping. Smaller screws such as switch and device screws often take a #1; larger structural fasteners may take a #3.
5) Is this bit coated to resist rust in a damp truck or jobsite box?
The bit carries a black oxide finish over steel, which resists corrosion and extends working life in wet or dirty jobsite conditions. It is a thin conversion coating, so it does not change the tip geometry or how the shank seats in a collet.
6) Is the Irwin 1837456 sold as a single bit or a multi-pack?
The 1837456 is one Phillips #2 power bit, a single-piece bit on a 1/4 inch quick-change shank. There is a single model on it, so if you are stocking a crew or an MRO cage, order the quantity you need rather than expecting a set.
