88808 Speedbor Spade Drill Bit, 1/2 In., 6 In. Oal

The Irwin 88808 Speedbor Spade Drill Bit is a flat-flute wood boring bit designed for fast, clean holes in lumber and wood-based materials. The 1/2-inch diameter bit features a blue groove point and cutting edge for faster chip removal. Double cutting spurs scribe the outside of the hole to minimize breakout and tear-out on exit, producing a cleaner hole edge without splintering on delicate surfaces.

The grooved hex shank prevents slipping inside the drill chuck or bit extension, ensuring secure engagement and consistent cutting performance. The hex design also fits all standard quick-change chucks, speeding up bit changes on the job site so you can work faster without fumbling with traditional shank styles.
