Irwin 88807 Speedbor Wood Boring Bit 7/16 in 6 in Length

Product Description

The IRWIN 88807 is a Speedbor wood boring bit designed for drilling clean or rough holes in wood and wood-composite materials. The bit features a 7/16 inch cutting diameter, a 6 inch overall length, and a 1/4 inch shank for compatibility with standard drill chucks and quick-change systems. It is suited for rough-in framing, finish carpentry, and general wood boring tasks where consistent hole diameter and penetration speed are required. Licensed carpenters, electricians, and plumbers commonly reach for this style of bit when boring through studs, plates, and joists during new construction or remodel work.

This bit is appropriate for residential and light commercial applications where wood boring is part of the daily workflow. Typical use cases include running conduit, pipe, or cable through framing members, as well as general woodworking and cabinetry. The 6 inch length provides enough reach to clear standard framing lumber without an extension, and the 1/4 inch shank fits most corded and cordless drill drivers used in the field.

Key Features

• 7/16 inch cutting diameter for consistent, repeatable hole sizing
• 6 inch overall length for reach into standard framing assemblies
• 1/4 inch shank compatible with standard chucks and quick-change systems
• Designed for both fast rough boring and cleaner finish holes in wood
• Compact weight of 0.09 pounds for low fatigue during repetitive use

Compatibility

Designed as an OEM-style wood boring bit suitable for use with standard 1/4 inch chuck and quick-change drill drivers used in wood framing, rough-in, and finish carpentry applications.

Installation Notes

This bit is installed and operated by carpenters, electricians, and plumbers using corded or cordless drill drivers. Secure the 1/4 inch shank fully into the chuck or quick-change adapter before operating. Wear appropriate eye protection when boring, and clear chips from the hole periodically to reduce heat buildup and bit wear. Follow applicable codes such as NEC or IPC when boring through structural members for trade rough-in work.
