The 7mm Draper Expert HSS Cobalt Drill Bit is perfectly sized for medium-duty drilling tasks across a range of materials. With its compact 180mm overall length, this bit offers excellent control and manoeuvrability whilst maintaining the rigidity required for accurate hole placement. The 7mm diameter makes it particularly versatile for electrical installations, mechanical assembly work, and general metalworking applications. Manufactured from high-speed steel with 5% cobalt content, this drill bit delivers exceptional wear resistance and maintains its sharp cutting edge far longer than standard HSS bits.
