Faithfull Cobalt Jobber Drill Bit

This 5.5mm Faithfull Professional Cobalt Jobber Drill Bit is supplied in a convenient pack of 2, offering a versatile size for general metalworking and engineering applications. The 5.5mm diameter provides an intermediate option between standard sizes, ideal for specific clearances and mounting applications in stainless steel and hardened metal fabrication. Manufactured from premium M35 HSSE grade steel with 5% cobalt content, this bit provides exceptional heat resistance and cutting performance. The cobalt enrichment significantly extends tool life compared to standard HSS alternatives, maintaining cutting efficiency even during prolonged drilling operations in abrasive and heat-generating materials. The fully ground construction delivers optimal cutting geometry and efficient chip evacuation, whilst the 135° non-slip split point guarantees accurate centring and reduces drilling effort. Produced in accordance to DIN 388 standards for guaranteed precision tolerances and geometric accuracy. Ideal for alloy steels, carbon steels, cast iron, hardened alloy steels, stainless steels, high temperature alloys, titanium alloy, high strength steel and carbon fibre composite materials.
