Faithfull Cobalt Jobber Drill Bit 10mm Pack of 1

The 10mm Faithfull Professional Cobalt Jobber Drill Bit is supplied individually, reflecting its larger diameter and suitability for more substantial drilling operations in industrial metalworking. This size is frequently used for creating mounting holes, dowel pins and larger fastener clearances in steel fabrication and heavy engineering applications. Manufactured from premium M35 HSSE grade steel with 5% cobalt content, this bit offers exceptional performance when drilling through demanding materials. The cobalt enrichment provides superior heat resistance, which is particularly important at this larger diameter where heat generation and material removal rates are significantly higher. The fully ground construction ensures optimal cutting geometry, whilst the 135° non-slip split point delivers precise centring even on curved or uneven surfaces. Produced to DIN 388 standards for guaranteed precision tolerances and geometric accuracy. This professional-grade bit excels in alloy steels, carbon steels, cast iron, hardened alloy steels, stainless steels, high temperature alloys, titanium alloy, high strength steel and carbon fibre composite materials.
