Irwin IWAX2006 Self-feed Drill Bit 1.75 in Hex Shank

Product Description

The IRWIN IWAX2006 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 1.75 inches in cutting diameter with a 6 inch overall length and features a 0.4375 inch hex shank for secure chuck engagement. An oxide coating helps resist corrosion and reduces surface friction during cutting. This bit is used by electricians, plumbers, and HVAC installers who need to run conduit, pipe, or duct penetrations through structural members.

Self-feed bits like the IWAX2006 are the standard choice for boring large-diameter holes through 2x framing and engineered wood panels. The self-feeding tip pulls the bit into the material without requiring sustained downward pressure from the operator, which reduces fatigue during repetitive boring tasks. Typical applications include rough-in drilling for electrical wiring runs, plumbing supply and drain lines, and HVAC refrigerant line sets passing through wall plates and floor joists.

Key Features

• 1.75 inch cutting diameter suited for conduit, pipe, and line set rough-in work
• 0.4375 inch hex shank provides positive tool engagement and resists slipping under load
• 6 inch overall length reaches through standard 2x framing in a single pass
• Oxide coating reduces corrosion and lowers cutting friction
• Self-feeding tip pulls into wood without sustained operator pressure
• Steel construction maintains edge integrity through repeated use in wood framing

Compatibility

Designed for use with drills and right-angle drill attachments that accept a 0.4375 inch hex shank. Suitable for boring through softwood and hardwood framing, OSB, and similar wood-based materials common in residential and light commercial rough-in work.

Installation Notes

Licensed electricians, plumbers, and HVAC technicians typically install self-feed bits during rough-in phases before wall finishes are applied. Ensure the drill is set to an appropriate speed for large-diameter boring and that the workpiece is secured before starting the cut. Wear eye protection when boring through framing, as self-feed bits eject chips and debris at high velocity. Inspect the cutting edges before each use and replace the bit if the tip or outer spurs show significant wear.
