This 4.5mm Faithfull Professional Cobalt Jobber Drill Bit comes in a practical pack of 2, providing a versatile mid-range size for general metalworking applications. The 4.5mm diameter is frequently used for clearance holes, mounting fixings and general fabrication work where reliable performance in stainless steel and hardened materials is essential. Manufactured from premium M35 HSSE grade steel with 5% cobalt content, this bit offers exceptional durability and cutting performance. The cobalt enrichment provides superior heat resistance, allowing the bit to maintain its cutting efficiency during extended drilling operations in demanding materials that generate significant heat. The fully ground construction ensures optimal cutting geometry, whilst the 135° non-slip split point delivers precise centring even on curved or uneven surfaces. Produced to DIN 388 standards for guaranteed precision tolerances and geometric accuracy. This professional-grade bit excels 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.
