Irwin IWAX2009 Self-feed Drill Bit 2.563in Hex Shank

Product Description

The IRWIN IWAX2009 is a self-feed drill bit designed for fast, aggressive boring through wood framing, engineered lumber, and similar materials encountered in residential and light commercial construction. The bit measures 2.563 inches in diameter with a 0.4375-inch hex shank and an overall length of 6.00 inches. It is constructed from steel with an oxide coating that helps resist corrosion and reduce friction during cutting. Electricians, plumbers, and HVAC installers commonly use self-feed bits when pulling wire or pipe through structural members where speed and clean entry matter.

This bit is suited for through-boring applications in wood studs, joists, and plates during rough-in work. The hex shank provides positive engagement in most 3/8-inch and 1/2-inch keyed or keyless drill chucks and quick-change chuck systems. The oxide coating helps extend service life in repetitive boring tasks on the job site. It is sold as a single bit and is appropriate for trade professionals who need a reliable large-diameter boring solution for standard rough-in scenarios.

Key Features

• 2.563-inch cutting diameter for large-bore rough-in applications
• 0.4375-inch hex shank for secure chuck engagement and quick-change compatibility
• 6.00-inch overall length suits standard framing depths
• Oxide coating resists corrosion and reduces cutting friction
• Steel construction for durability in repetitive job-site use

Compatibility

Designed as an OEM-style self-feed drill bit for use with standard 3/8-inch or 1/2-inch variable-speed drills and right-angle drill drivers equipped with hex-compatible chucks.

Installation Notes

Self-feed bits should be operated with a heavy-duty drill or right-angle driver set to a controlled speed to prevent bit grab in dense lumber. Ensure the drill is powered off and trigger locked before changing or inspecting the bit. Follow applicable building codes, including NEC rough-in clearance requirements when boring for electrical runs. Avoid forcing the bit through engineered lumber with embedded fasteners, as this can damage the cutting edge.
