Available at Tooled Up
The 4mm Faithfull Professional Cobalt Jobber Drill Bit is supplied in a pack of 2, providing excellent versatility for one of the most commonly used drill bit sizes in professional workshops. This diameter is perfect for general metalworking applications and is frequently specified for clearance holes in steel fabrication and engineering work. Featuring M35 HSSE grade steel construction with 5% cobalt content, this bit delivers exceptional performance when drilling hard and abrasive materials. The cobalt enrichment provides superior heat resistance, allowing the bit to maintain its hardness and cutting edge even under demanding conditions that would quickly dull standard HSS bits. Manufactured to DIN 388 standards with a fully ground finish, this drill bit ensures high precision tolerances and geometric accuracy. The 135° non-slip split point provides precise centring and reduces the effort required to start holes. Ideal for alloy steels, carbon steels, cast iron, hardened alloy steels, stainless steels, high temperature alloys, titanium alloy, high strength steel and carbon fibre composites.
