Draper Expert HSS Cobalt Drill Bit 11mm Pack of 1
The 11mm Draper Expert HSS Cobalt Drill Bit is designed for larger-diameter drilling applications across metalworking and engineering disciplines. This popular metric size is commonly specified for structural work, heavy fabrication, and mechanical installations where robust fastening holes are required. The 230mm overall length provides the reach necessary for drilling through substantial material thicknesses whilst maintaining sufficient rigidity to prevent deflection and ensure accurate hole placement. Enhanced with 5% cobalt content, this high-speed steel drill bit offers exceptional performance when working with harder materials that would quickly defeat standard HSS bits. The cobalt addition significantly improves both wear resistance and heat tolerance, allowing the bit to maintain its cutting edge through extended use in stainless steel, cast iron, and hardened alloys. This superior durability translates to fewer bit changes, improved productivity, and more consistent hole quality throughout demanding projects. Features and Benefits: • 11mm diameter ideal for structural and heavy-duty applications • 230mm length provides excellent reach and accessibility • 5% cobalt addition delivers exceptional wear resistance • Superior heat resistance maintains cutting performance • Effective in materials where conventional bits fail prematurely Contents: • 1 x HSS Cobalt Drill Bit, 11 x 230mm
