Expert HSS Cobalt Drill Bit 12.4mm Pack 1

The 12.4mm Draper Expert HSS Cobalt Drill Bit represents the largest diameter in this range, offering precision sizing for specialist applications requiring exact hole dimensions. This intermediate size is particularly valuable for engineering work where standard metric increments don't provide the specific clearance needed for particular fasteners or components. The 230mm overall length delivers excellent reach for drilling through substantial materials or accessing recessed areas whilst maintaining the rigidity essential for accurate hole placement. Featuring high-speed steel construction with 5% cobalt content, this drill bit provides exceptional durability when working with challenging materials. The cobalt addition significantly enhances the bit's ability to resist wear and withstand the heat generated during drilling operations, allowing it to maintain its sharp cutting edge far longer than standard HSS alternatives. This superior performance is particularly evident when drilling stainless steel, hardened alloys, and other tough materials, resulting in cleaner holes and extended tool life.
