The Irwin 316015 Pro Cobalt Drill Bit Set is a 15-piece collection of high-speed steel drill bits designed for demanding metalworking applications. This set delivers reliable performance when drilling through tough, abrasive materials including hardened steel, alloy metals, cast iron, and stainless steel. Built from M-42 8% cobalt high-speed steel, these bits resist heat buildup and abrasion that can dull ordinary drill bits.
The 135-degree split point geometry reduces feed pressure for easier penetration into metal surfaces. The included rubber-sided storage case with sliding latch keeps all bits organized and accessible, with a design that provides added security and durability for transport to any job site.
