Draper Expert HSS Cobalt Drill Bit

The 10.5mm Draper Expert HSS Cobalt Drill Bit delivers precision drilling capability for applications requiring exact hole dimensions between standard metric sizes. With its 230mm overall length, this bit provides excellent reach for drilling through thicker materials or accessing recessed work areas whilst maintaining the rigidity essential for accurate hole placement. The intermediate diameter makes it particularly valuable for engineering and fabrication work where precise clearances are critical. The cobalt-enhanced high-speed steel construction sets this bit apart from conventional alternatives, offering exceptional wear resistance and heat tolerance. The 5% cobalt content allows the bit to maintain its sharp cutting edge even when drilling through stainless steel, hardened alloys, and other materials that quickly dull standard HSS bits. This results in cleaner holes, reduced drilling effort, and significantly extended service life, making it a cost-effective choice for demanding applications.
