Speedbor 1891775 Irwin Tools Blue-Groove Spade Bits, 12-Piece, Slim Case

IRWIN Tools 1891775 SPEEDBOR BLUE-GROOVE Spade Bits, 12-Piece, Slim Case. Blue-Groove point and cutting edge remove chips 4x faster than standard spade bits for cleaner holes and less binding. Dual-cutting spurs scribe the outside of the hole reducing breakout. 10% larger shank for added durability. Shorter bit length gets into confined spaces (between studs) where standard lengths will not fit. Grooved hex shank is compatible with all 1/4-inch quick-change chucks, including impact drills and reduces slipping in standard chucks.
