This IRWIN SPEEDBOR 8-Piece Spade Drill Bit Set includes drill bits featuring 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, these spade bits resist slipping in the drill chuck or bit extension. The drill bit set comes in a Pro Set case constructed from molded ABS resin for durability, which features a sliding latch design for security.
