Irwin Industrial Tools’ standard length Speedbor MAX spade bits have a tri-flute design for chip ejection. Cutting spurs have 3 cutting edges, and a full screw tip allows the bit to self-feed. A grooved hex shank prevents slipping in the drill chuck or bit extension. The bits fit all standard ¼-in. quick-change chucks. Visit www.ecmag.com/info
