The Irwin Speedbor� MAX SPEED� wood drilling bit is the fastest Speedbor� ever. The speed tip features a full screw point that allows bit to self-feed, as well as three cutting spurs for faster, cleaner holes, less breakout and extended drilling life. The tapered tri-flute design allows for faster chip ejection and less binding. Its grooved hex shank prevents slipping and fits all standard 1/4 in quick change chucks, including impact drills.
