Draper Expert HSS Cobalt Drill Bit 9.3mm Pack of 1

The 9.3mm Draper Expert HSS Cobalt Drill Bit combines precision sizing with extended reach, featuring a 230mm overall length that provides excellent accessibility for deeper drilling applications. This intermediate diameter is particularly valuable for specialist engineering work where standard metric increments don't provide the exact clearance required. The longer format makes it ideal for drilling through thicker materials or reaching recessed areas whilst maintaining drilling accuracy. The high-speed steel construction enhanced with 5% cobalt content delivers outstanding durability when working with challenging materials. This cobalt addition significantly improves the bit's heat resistance and wear characteristics, allowing it to maintain its sharp cutting edge through extended use in harder materials such as stainless steel, cast iron, and hardened alloys. The result is consistent drilling performance and reduced tooling costs over time. Features and Benefits: • 9.3mm precision diameter for specialist applications • Extended 230mm length provides superior reach • 5% cobalt content prevents premature wear • Excellent heat resistance during continuous operation • Maintains cutting performance in demanding materials Contents: • 1 x HSS Cobalt Drill Bit, 9.3 x 230mm
