Irwin 87950 Spade Drill Bit Set 3 Piece 1 Inch Hex Shank

Product Description

The IRWIN 87950 is a 3-piece spade drill bit set designed for boring holes in wood and wood composite materials. The set covers sizes from 1/2 inch to 1 inch in 1/4-inch step increments, making it a practical choice for rough-in work, framing, and general carpentry. Each bit features a 1/4-inch hex shank for positive engagement in quick-change chucks and standard drill drivers. The bits are manufactured from carbon steel with a bright, uncoated finish. At 0.27 pounds, the set is compact enough for a tool bag or service pouch. Electricians, plumbers, and general contractors use this set for running wire, pipe, and conduit through wood framing.

This set is suited for residential and light commercial applications where wood drilling is required. Typical scenarios include boring through wall plates, floor joists, and wood studs during rough-in phases of electrical or plumbing installations. The 1/4-inch hex shank is compatible with standard drill drivers and quick-change bit holders, reducing tool changes during repetitive drilling tasks. The 4-3/4-inch overall length fits most standard drill drivers without interference in tight framing cavities.

Installation Notes

Spade bits are installed by electricians, plumbers, and carpenters during rough-in work. Confirm the drill driver is set to an appropriate clutch or speed setting before boring to prevent bit binding or kickback. Always ensure the workpiece is secured before drilling. Follow applicable trade codes, including NEC and IPC requirements, when boring through structural members.
