Irwin 88815 Speedbor Wood Boring Bit 15/16 in 6 in

Product Description

The IRWIN 88815 is a Speedbor wood boring bit designed for drilling fast, rough, or clean and exact holes in wood. The bit features a 15/16-inch cutting diameter, a 6-inch overall length, and a 1/4-inch shank for secure chuck retention. It is built for use with standard power drills and is suited to framing, rough-in, and finish carpentry applications. Electricians, plumbers, and general contractors reach for this bit when running wire or pipe through wood studs and joists. The 1/4-inch shank accommodates quick-change chuck systems common on cordless and corded drills.

The 88815 is appropriate for residential and light commercial rough-in work where clean entry and exit holes are required. Its geometry handles both through-drilling and shallow boring tasks in dimensional lumber, engineered wood, and similar materials. Tradespeople running conduit, low-voltage cabling, or supply lines through framed walls will find the 15/16-inch diameter well-suited to common rough-in clearances.

Installation Notes

This bit is installed and used by electricians, plumbers, HVAC technicians, and carpenters performing rough-in drilling.
