[1-(Pack)]
The IRWIN Speedbor Max Speed Wood Drill Bit is the fastest Speedbor ever. The speed tip features a full screw tip that allows the bit to run itself, as well as three (3) cutting spurs for faster, cleaner holes, less breakout, and extended drilling life. The tapered tri-flute design allows faster chip ejection and less binding. Its grooved hex shank prevents slipping and fits all standard 1/4" quick change chucks including impact drills.
