Irwin 3041003 Spade Drill Bit Set 3 Pc 0.625-1 Inch Hss

Product Description

The IRWIN 3041003 is a 3-piece spade drill bit set designed for boring clean holes in wood and wood-composite materials. The set covers three hole sizes ranging from 0.625 inches to 1 inch, giving electricians, plumbers, and carpenters the most commonly needed sizes for running conduit, pipe, and cable through framing and structural lumber. All three bits are machined from high-speed steel with a bright, uncoated finish. Each bit measures 6 inches in overall length, providing adequate reach for standard framing applications without requiring a bit extension. The full set weighs 0.6 pounds, making it a compact addition to a tool bag or service van.

This set is suited for residential and light commercial rough-in work where drilling through wood studs, joists, and plates is a routine task. Electricians drilling wire-chase holes, plumbers running drain or supply lines through framing, and HVAC technicians routing low-voltage or refrigerant line sets through wood structure will all find the three included sizes practical. The 6-inch shank length is compatible with standard drill chucks on corded and cordless drills used in trade applications.

Installation Notes

Spade bits are installed by trade professionals including electricians, plumbers, and HVAC technicians during rough-in phases. Ensure the drill is set to an appropriate speed for the wood species and bit diameter before drilling. Secure the workpiece before applying pressure, and back the bit out periodically on deeper cuts to clear chips and reduce heat buildup. Always confirm no embedded fasteners, wiring, or utility lines are present in the material before drilling.
