The IRWIN 88813 is a Speedbor wood boring drill bit designed for fast, clean, and accurate hole drilling in wood and wood-composite materials. With a 13/16 inch cutting diameter and a 1/4 inch hex shank, this bit seats securely in standard drill chucks and quick-change chuck systems. The 6 inch overall length provides the reach needed for framing, rough-in drilling, and finish carpentry tasks. At 0.11 pounds, it is a lightweight, single-piece tool suited for everyday use by electricians, plumbers, HVAC installers, and carpenters who drill wood bores as part of standard rough-in and installation work.
The 88813 is well-suited for residential and light commercial rough-in applications where wood boring through studs, joists, plates, and framing members is required. It handles both fast rough drilling and cleaner finish-quality holes, making it a versatile option across framing, mechanical, and electrical trades. The 1/4 inch shank is compatible with standard drill chucks and quick-change driver systems commonly found on cordless and corded drills used in the field.
Designed for use with standard corded and cordless drills equipped with a 1/4 inch or larger chuck. Fits quick-change driver systems that accept 1/4 inch hex shanks.
Wood boring bits of this type are installed and used by electricians, plumbers, HVAC technicians, and carpenters during rough-in phases. Secure the bit fully in the chuck before operation and confirm the workpiece is clamped or otherwise stabilized. Follow applicable codes such as NEC or IPC when sizing bores through structural members, as notching and boring limits apply. Inspect the bit for wear or damage before each use and replace if the cutting tip shows deformation.
