Irwin 87908 Speedbor Wood Boring Bit 0.5x4 in Tight Access

Product Description

The IRWIN INDUSTRIAL TOOL CO 87908 is a Speedbor wood boring bit designed for drilling clean, straight holes in confined work areas. Measuring 0.5 inches in diameter and 4 inches in overall length, its shorter profile is engineered specifically for situations where a standard-length spade bit cannot maneuver. This bit is commonly used by electricians, plumbers, and HVAC installers who need to bore through framing members in tight quarters. The single-spur cutting tip delivers fast, accurate penetration through dimensional lumber and engineered wood with minimal tearout.

This bit is built for trade work in residential and light commercial construction where clearances are limited. The compact 4-inch length allows access between wall studs, between rafters, and inside cabinet interiors where full-length bits would contact surrounding framing or surfaces before completing a hole. It is a common tool on rough-in jobs for low-voltage wiring runs, pipe penetrations, and duct access holes in finished or framed spaces.

Key Features

• 0.5-inch diameter bore in a 4-inch overall length for maximum reach in tight spaces
• Shorter length allows work between studs, rafters, and inside cabinets without obstruction
• Drills straight holes in confined areas where standard spade bits cannot fit
• Single-piece steel construction for durability in repetitive rough-in applications
• Packaged individually on a carded display for jobsite storage and point-of-purchase identification

Compatibility

Designed as a standard 0.5-inch wood boring bit compatible with any 3/8-inch or 1/2-inch chuck cordless or corded drill driver.

Installation Notes

Wood boring bits of this type are installed by electricians, plumbers, and HVAC technicians during rough-in phases. Ensure the drill is set to an appropriate speed for wood boring and that the work surface is secured before drilling. Verify there are no live wires, pressurized lines, or structural fasteners in the intended bore path before starting. Always wear appropriate eye protection when drilling through framing lumber or engineered wood panels.
