Speedbor 88811 Spade Drill Bit, 11/16 In. Dia, 6 In. OAL

The Irwin Speedbor 88811 is a spade drill bit designed for boring clean, fast holes in wood and soft materials. This bit drills holes significantly faster than standard spade bits while maintaining consistent cutting efficiency throughout its life. Whether you're framing, decking, installing wiring, or building cabinetry, this 11/16-inch diameter bit provides the clearance you need for pilot holes, fasteners, or conduit runs.

The blue groove point and cutting edge work together with double cutting spurs that scribe the outside of the hole to reduce breakout. The grooved hex shank grips securely in any standard quick-change chuck or bit extension, reducing cam-out and wobble even under high torque. This design minimizes the bounce and chatter that can slow down drilling, giving you smoother control and faster results on every job.
