Draper Expert HSSE M35 Cobalt Drill Bit

The Draper Expert HSSE M35 Cobalt Drill Bits deliver professional-grade performance for demanding metalworking applications. Manufactured from M35 high speed steel with 5% cobalt content, these drill bits provide exceptional durability, superior abrasion resistance and enhanced heat protection when working with the toughest materials.

Each bit is fully ground with a precision 135° split point that ensures accurate centring and prevents drill wander, giving you clean, precise holes from the first contact. The cobalt construction makes them ideal for drilling through alloy steel, titanium alloys, stainless steel, hardened steel, cast iron and carbon steel.

Available in sizes from 1mm to 13mm, with smaller sizes supplied in packs of 2 and larger sizes as individual bits. For optimal results and extended service life, use in conjunction with a cooling agent. All sizes are compatible with standard 10/13mm chucks, making them suitable for most professional drill applications.
