Irwin 88814 Speedbor Wood Boring Bit 7/8 in 6 in

Product Description

The IRWIN 88814 is a Speedbor wood boring drill bit designed for fast, clean, and accurate hole drilling in wood and wood-based materials. At 7/8 inch in diameter with a 6 inch overall length and a 1/4 inch shank, this bit fits standard drill chucks and quick-change adapters common in residential and commercial construction. It is suited for applications where both speed and hole quality matter, such as drilling through framing lumber, studs, joists, or dimensional boards. Carpenters, electricians, and plumbers routinely use bits like this when boring through structural members for wire or pipe runs.

The 88814 is used in rough-in and finish carpentry applications where a reliable, consistently sized hole is required through wood framing or sheeting. Its 6 inch length gives enough reach to bore through standard lumber without extensions, and the 1/4 inch shank allows use in compact drill drivers and right-angle drill attachments common in tight framing cavities.

Key Features

• 7/8 inch cutting diameter for standard rough-in and finish boring tasks
• 6 inch overall length provides reach through single-layer framing members
• 1/4 inch shank compatible with standard chucks and quick-change chuck systems

Compatibility

Designed as an OEM-style wood boring bit compatible with standard 3-jaw drill chucks and 1/4 inch quick-change chuck adapters used in corded and cordless drill drivers.

Installation Notes

This bit is installed and used by carpenters, electricians, and plumbers working with wood framing. Ensure the bit shank is fully seated and the chuck is firmly tightened before drilling. When boring through structural members, verify lumber is secured and confirm clearances per applicable local building codes. Inspect the bit for wear or damage before each use and replace if the tip or spurs are chipped.
