The Irwin SPEEDBOR 7/8-by- 6-in MAX spade bit is a fast SPEEDBOR spade bit that features a Tri-foil design with a fast chip ejection. The SPEEDBOR MAX has cutting spurs with three cutting edges for added durability, as well as a full screw tip allows the bit to self feed. The grooved hex shank prevents slipping in drill chuck or bit extension, while the bit itself fits all standard 1/4-in quick change chucks.
