The Draper Expert 25 Piece HSSE M35 Cobalt Drill Bit Set is a professional-grade drilling solution engineered for demanding metalworking applications. Manufactured from M35 high-speed steel with 5% cobalt content, these drill bits deliver exceptional longevity, superior abrasion resistance and enhanced heat protection when working with hard materials. Each drill bit features a fully ground construction with a 135° split point geometry that ensures precise centring from the first contact, effectively preventing drill wander on challenging surfaces. This design characteristic makes them particularly well-suited for drilling stainless steel, hardened steel, titanium alloys, cast iron, alloy steel and carbon steel. The comprehensive 25-piece set provides drill bits ranging from 1.0mm through to 13.0mm in 0.5mm increments, offering versatility across a wide range of metalworking tasks. All bits feature round shanks compatible with standard 10mm and 13mm chucks found on most drills. For optimal performance and extended service life, Draper recommends using these cobalt drill bits in conjunction with an appropriate cooling agent. The set is supplied in a practical plastic storage case for organised workshop or site storage.
