Irwin Speedbor Max Drill Bit Set – 6 Piece

Take on any wood-boring task with the Irwin Speedbor Max Drill Bit Set, engineered for speed, durability, and effortless chip removal. This versatile 6-piece collection includes the most popular spade bit sizes—1/2", 5/8", 3/4", 7/8", 1" and 1-1/4"—so you’ll always have the right bit on hand for through-holes, rough carpentry, framing, and finish work. Constructed of high-speed steel with a full screw tip, Speedbor Max bits feed themselves, delivering clean, accurate holes without walking or wandering.

Housed in a clear-lid, stackable storage case, these wood bits are easy to view, organize, and transport. Each bit features chamfered cutting spurs and a parabolic “Blue Groove” flute design that aggressively ejects chips, keeping your hole clear and your work moving fast. The impact-rated 1/4" hex shank locks securely into quick-change and impact driver chucks, preventing slip and optimizing torque transfer.
