Irwin 88809 Speedbor Wood Boring Bit 9/16 in 6 in

Product Description

The IRWIN 88809 is a Speedbor wood boring drill bit designed for fast, efficient drilling in wood framing, rough carpentry, and finish work. The 9/16-inch cutting diameter delivers clean entry points for conduit, pipe, cable, and fastener clearance holes. A 1/4-inch hex shank provides secure chuck engagement in standard drills and impact drivers, while the 6-inch overall length gives tradespeople the reach needed for typical structural and finish applications. Electricians, plumbers, and general contractors rely on bits in this class for production drilling through studs, joists, and plates.

This bit is suited for residential and light commercial construction where accurate, repeatable wood boring is required. Typical applications include drilling stud walls for electrical rough-in, plumbing pipe runs, and low-voltage cabling. The 1/4-inch hex shank makes it compatible with quick-change bit holders, improving workflow on high-volume drilling tasks. The 6-inch length accommodates drilling through standard 2x framing members with clearance to spare.

Installation Notes

Installation of this bit is performed by electricians, plumbers, and carpenters during rough-in phases. Ensure the drill or driver is powered off and the battery disconnected before changing bits. Use appropriate eye protection when boring through wood, and verify there are no embedded fasteners or utilities behind the work surface before drilling. Follow applicable code requirements such as NEC boring distance rules for electrical rough-in when sizing hole placement near the stud edge.
