Product Description
The IRWIN 26141507 is a spade-style wood drill bit engineered for fast, clean boring in wood and wood-based materials. Part of the Speedbor line, this bit delivers efficient material removal through a flat paddle profile with a center point that registers quickly on the workpiece surface. At 3/8 inch cutting diameter and 18.5 inches in overall length, it reaches deep into framing, joists, and thick lumber where shorter bits cannot. Carpenters, electricians, and plumbers rely on spade bits like this one to run conduit, pipe, and cable through structural members during rough-in work.
This bit is suited for residential and light commercial applications where through-holes in dimensional lumber, engineered wood, or panel materials are required. The extended length makes it particularly practical for drilling through multiple framing members without repositioning. It is commonly used during electrical rough-in to pass wire through studs and top plates, as well as in plumbing rough-in for supply and drain line penetrations. The bit fits any standard drill or right-angle drill accepting a 1/4-inch hex or round shank.
Key Features
- 3/8 inch cutting diameter for standard wire and pipe rough-in holes
- Extended 18.5-inch length reaches through deep framing assemblies
- Spade paddle profile provides fast stock removal in softwood and hardwood
- Center point tip registers on the workpiece for accurate hole placement
- Compatible with standard drill chucks and quick-change hex adapters
Compatibility
Designed as an OEM-style replacement and standard accessory for use with any corded or cordless drill accepting a standard round or hex shank spade bit.
Installation Notes
This bit is installed and used by electricians, plumbers, and carpenters performing rough-in drilling. Secure the workpiece before drilling and operate the drill at a moderate speed appropriate for the wood species and bit diameter. When drilling near structural members, follow applicable building codes including NEC and IFGC clearance requirements for bored holes. Withdraw the bit periodically on deep passes to clear chips and reduce heat buildup.
