Faithfull Cobalt Jobber Drill Bit – FAIPP800COB

The 8mm Faithfull Professional Cobalt Jobber Drill Bit is supplied as a single unit, representing a popular size for substantial drilling operations in professional metalworking. The 8mm diameter is frequently specified for mounting bolts, clearance holes and general engineering work where reliable performance in demanding materials is essential. Crafted from M35 HSSE grade steel with 5% cobalt content, this drill bit delivers outstanding durability and extended tool life. At this diameter, the cobalt additive provides crucial heat resistance, enabling the bit to maintain its cutting efficiency during extended drilling operations in thick sections of stainless steel and hardened alloys. Featuring fully ground construction and a precision 135° non-slip split point, this bit ensures accurate centring and reduces the effort required to start holes in hard surfaces. Manufactured 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.
