IRWIN 88813 Speedbor 13 16 Spade Drill Bit

This IRWIN SPEEDBOR Standard-Length Spade Drill Bit features a Blue-Groove point and cutting edge for fast chip removal. The double-cutting spurs scribe the outside of the hole to help reduce breakout, and the large shank design helps keep the bit durable. With a grooved hex shank, this wood drill bit will resist slipping in the drill chuck or bit extension and fits most standard quick-change chucks.
