Faithfull Cobalt Jobber Drill Bit

This 1mm Faithfull Professional Cobalt Jobber Drill Bit comes in a pack of 2, providing an essential ultra-fine drilling solution for precision engineering and delicate metalworking applications. The 1mm diameter is ideal for micro-drilling operations, creating pilot holes for miniature fixings and working with electronics, instrumentation and fine mechanical assemblies.

Despite its small diameter, this bit is constructed from robust M35 HSSE grade steel with 5% cobalt content, delivering exceptional durability and heat resistance. The cobalt additive is particularly valuable at this fine size, where standard bits can quickly lose their edge when drilling hard materials.

Manufactured to exacting DIN 388 standards, this drill bit features a fully ground finish and precision 135° non-slip split point for accurate centring. The split point design is crucial at this diameter, preventing walking and ensuring holes are placed exactly where required. Suitable for drilling alloy steels, carbon steels, cast iron, hardened alloy steels, stainless steels, high temperature alloys, titanium alloy, high strength steel and carbon fibre composite materials.
