The Draper Expert 19 Piece HSSE M35 Cobalt Drill Bit Set is a professional-grade drill bit collection engineered for demanding metalworking applications. Manufactured from M35 high speed steel with 5% cobalt content, these drill bits deliver exceptional durability, abrasion resistance and heat protection when working with hard materials. The fully ground construction and 135° split point geometry ensures precise centring and prevents drill wander, allowing accurate hole placement even on challenging metal surfaces. This comprehensive 19-piece set covers sizes from 1.0mm to 10.0mm in 0.5mm increments, providing versatile coverage for a wide range of drilling tasks. The cobalt-enriched steel construction makes these bits particularly suitable for use with alloy steel, titanium alloys, stainless steel, hardened steel, cast iron and carbon steel – materials that would quickly dull standard HSS bits. For optimal performance and extended tool life, it's recommended to use these cobalt drill bits in conjunction with a cooling agent, particularly when drilling harder materials or working at higher speeds. The round shank design is compatible with standard 10/13mm chucks, ensuring straightforward fitment to most professional and workshop drill equipment. The complete set is supplied in a protective plastic case for organised storage and transport between job sites.
