Irwin 87914 Speedbor Wood Boring Bit 7/8 X 4 Inch Short

Product Description

The IRWIN INDUSTRIAL TOOL CO 87914 is a Speedbor wood boring bit designed for drilling clean, straight holes in wood where space is limited. At 7/8 inch in diameter and 4 inches in overall length, this bit is shorter than standard spade bits, making it practical in confined spaces where a full-length bit cannot swing freely. It is used by electricians, plumbers, HVAC technicians, and carpenters who need to bore through framing members, cabinetry, or structural lumber during rough-in work.

This bit is suited for residential and light commercial applications where trade professionals need to run conduit, pipe, or wire through wood framing. The short overall length of 4 inches gives it the clearance needed to operate between studs, inside wall cavities, above rafter bays, and within cabinet interiors. It ships in a carded format and is available in a package quantity of six, making it practical for stocking a service van or tool bag.

Key Features

• 7/8 inch diameter cuts a consistent, clean hole for wire, conduit, or pipe pass-throughs
• 4 inch overall length provides access in tight framing cavities where longer bits cannot fit
• Speedbor design drills straight holes with reduced walking and drift
• Carded packaging keeps the bit protected and identifiable on a pegboard or shelf
• Package quantity of six supports multi-job stocking

Compatibility

Designed as an OEM-style replacement spade bit for use with standard 3/8 inch and 1/2 inch keyed or keyless drill chucks on corded or cordless drills.

Installation Notes

This bit is installed and used by electricians, plumbers, and HVAC technicians performing rough-in boring through wood framing. Confirm the drill chuck is fully tightened before operation. Always inspect the work area for hidden wiring, pipes, or structural fasteners before boring. Follow applicable NEC, IPC, or IFGC clearance requirements when drilling near structural members.
