Draper Expert HSS Cobalt Drill Bit

The 7.2mm Draper Expert HSS Cobalt Drill Bit offers precision sizing for specialist applications requiring exact hole dimensions. This intermediate size fills the gap between standard metric increments, making it invaluable for engineering work, tool and die making, and applications where precise clearances are critical. The 180mm overall length provides excellent control whilst maintaining sufficient reach for most drilling tasks. Constructed from high-speed steel with 5% cobalt addition, this bit delivers outstanding durability and wear resistance. The cobalt content significantly enhances the bit's ability to withstand heat generated during drilling, maintaining its cutting edge through extended use. This makes it particularly effective when working with harder materials that would quickly dull conventional HSS bits, ensuring consistent performance and reduced downtime.
