About this product
This 4.2mm Faithfull Professional Cobalt Jobber Drill Bit is supplied as a pack of 2, suited to precision drilling in demanding materials. Made from M35 HSSE grade steel with 5% cobalt content, it offers increased heat resistance and cutting performance compared with standard bits, helping it cope with the high temperatures generated when drilling tough metals. The bit is fully ground and features a 135° non-slip split point for accurate centring and reduced walking on hard surfaces. Manufactured to DIN 388 standards, it offers high precision tolerances and geometric accuracy. Suitable for heavy-duty industrial work 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. Overall length is 75mm.
