Standard-length spade bits feature Blue-Groove point and cutting edge for faster chip removal so it's four times faster than standard spade bits. Double-cutting spurs scribe the outside of the hole-reducing breakout. The shank is 10 percent larger shank for added durability. Grooved hex shank prevents slipping in drill chuck or bit extension. Spade bits fit all standard quick-change chucks.
