Irwin 88706 Spade Wood Drill Bit 3/8x16 in Long Shank

Product Description

The IRWIN INDUSTRIAL TOOL CO 88706 is a spade-style wood drill bit designed for boring large-diameter holes through wood framing, studs, and similar lumber. The 3/8-inch cutting diameter and 16-inch long shank make it well suited for reaching through deep assemblies where a standard-length bit cannot reach. It ships in a plastic pouch and is sold in a package of six, making it a practical restocking option for trade use. Electricians, plumbers, and HVAC technicians regularly use long-shank spade bits when running pipe, conduit, or wire through structural members.

This bit is used in residential and light commercial rough-in work where cables, pipes, or flexible conduit must pass through multiple stud bays or thick lumber assemblies. The extended 16-inch shank provides the reach needed to bore through dimensional lumber and engineered wood without repositioning. It is appropriate for cordless and corded drill drivers operating at standard variable speeds.

Key Features

• 3/8-inch cutting diameter suited for conduit, cable, and pipe rough-in applications

Compatibility

Designed for use with standard 3/8-inch or larger chuck cordless and corded drill drivers commonly used in electrical, plumbing, and HVAC rough-in installations.

Installation Notes

A licensed electrician, plumber, or HVAC technician typically uses this bit during rough-in framing stages before drywall is installed. Secure the workpiece before drilling and operate at a controlled speed to avoid tear-out on the exit face. When boring near structural members, follow applicable building codes regarding notching and boring limits for joists and studs. Inspect the bit for sharpness before each use and replace if the tip shows visible wear.
