Faithfull Cobalt Jobber Drill Bit

The 7mm Faithfull Professional Cobalt Jobber Drill Bit is supplied as a single unit, offering a popular size for medium-duty drilling operations in professional metalworking environments. This diameter is commonly used for mounting bolts, dowels and general fabrication work where robust performance in stainless steel and hardened materials is required. Constructed from M35 HSSE grade steel with 5% cobalt content, this drill bit provides outstanding heat resistance and cutting performance. At this mid-range diameter, the cobalt additive becomes especially valuable for maintaining cutting efficiency during sustained drilling operations in thick sections of demanding materials. Featuring a fully ground construction and precision 135° non-slip split point, this bit ensures accurate centring and reduces walking on hard surfaces. Manufactured in accordance to DIN 388 standards for guaranteed high precision tolerances and geometric accuracy. Perfect 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.
