Faithfull Cobalt Jobber Drill Bit

The 10.5mm Faithfull Professional Cobalt Jobber Drill Bit is supplied as a single unit, offering a specialist size for specific engineering applications where standard metric increments don't meet requirements. This diameter is particularly useful for enlarging 10mm holes or creating precise clearances in heavy-duty metalworking projects.

Constructed from M35 HSSE grade steel with 5% cobalt content, this bit provides outstanding performance in the most challenging materials. At this substantial diameter, the cobalt enrichment becomes especially important, delivering superior heat resistance and maintaining cutting efficiency during extended drilling operations in stainless steels and hardened alloys.

The fully ground construction ensures optimal cutting geometry and chip evacuation, whilst the precision 135° non-slip split point guarantees accurate centring and reduces drilling effort. Manufactured to DIN 388 standards for guaranteed precision tolerances and geometric accuracy. Ideal for heavy-duty industrial applications 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.
