Irwin IR88811 Wood Boring Bit Extension 11/16 in

Product Description

The IRWIN IR88811 is a wood boring bit extension designed to increase the reach of compatible spade and SPEEDBOR-style wood boring bits. It connects between the drill and the bit to allow drilling in deep or hard-to-reach locations within wood framing, joists, studs, and similar structural members. Electricians, plumbers, and carpenters rely on this type of extension when running conduit, pipe, or cable through walls and floor assemblies where standard bit length falls short. The IR88811 accommodates bits up to 11/16 inch in shank size.

This extension is suited for residential and light commercial construction and retrofit work. Typical applications include drilling through multiple studs or joists in series, reaching into wall cavities during rough-in, and accessing confined spaces where a drill chuck cannot be positioned close to the work surface. It is a standard tool-bag item for electricians and plumbers performing rough-in on new construction or remodel projects.

Installation Notes

Installation of this extension is performed by electricians, plumbers, and carpenters using a standard corded or cordless drill.

Follow all applicable safety guidelines for drilling into structural members, and verify no concealed wiring, pipe, or other hazards are present in the drilling path before starting.
