Description
The IRWIN INDUSTRIAL TOOL CO 3041005 is a Speedbor Max spade drill bit designed for fast, clean boring in wood and wood-based materials. Measuring 7/8 inches in diameter and 6 inches in length, this standard-length bit features a tri-flute design that accelerates chip ejection and keeps the cut clear during extended drilling. The full screw tip allows the bit to self-feed, reducing the hand pressure needed to drive through material. Cutting spurs include three cutting edges each for improved durability and cleaner hole edges. This package contains three bits. Sold as a 3-pack and weighing 0.81 pounds, the set suits production-level work where bit replacement frequency is high.
The 3041005 is suited for residential and light commercial rough-in applications, including drilling through studs and joists for wire and pipe runs. Electricians and plumbers commonly reach for spade bits in this diameter range when boring through dimensional lumber during new construction or remodel work. The 6-inch length provides enough reach for single-stud passes without requiring a bit extension in most framing scenarios. The grooved hex shank fits all standard 1/4 inch quick-change chucks, making it compatible with the impact drivers and drill/drivers already on the job.

Installation Notes
Spade bits are installed and removed by trade professionals using standard drill chucks or quick-change adapters no special tooling required. Always ensure the drill or driver is powered off and the battery is removed before changing bits. Secure the workpiece before drilling to prevent shifting, and back the bit out periodically on deep passes to clear chips and prevent overheating. Spade bits are intended for wood and wood composites only do not use on metal, masonry, or tile.
