The 3mm faithfull professional cobalt jobber drill bit is supplied in a pack of 2, offering a popular size for general precision drilling applications in metalworking. This diameter is commonly used for pilot holes, small fastener clearances and detailed fabrication work where accuracy and reliability are essential in stainless steel and hardened materials. Crafted from m35 hsse grade steel with 5% cobalt content, this drill bit provides outstanding heat resistance and cutting performance. The cobalt additive enables the bit to withstand the high temperatures generated when drilling challenging materials, maintaining its hardness and cutting edge throughout demanding operations. With its fully ground construction and precision 135° non slip split point, this bit delivers accurate centring and reduces the effort required to start holes. Manufactured in accordance to din 388 standards, it guarantees high precision tolerances and geometric accuracy. Perfect 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.
