Faithfull FAIPP1250COB Professional Cobalt Jobber Drill Bit Pre Packed 12.5mm

The 12.5mm Faithfull Professional Cobalt Jobber Drill Bit is supplied individually, offering a specialist size for precision engineering and heavy fabrication applications. This diameter provides an intermediate size between standard metric increments, ideal for creating specific clearances or meeting exact engineering specifications in demanding metalworking operations. Constructed from M35 HSSE grade steel with 5% cobalt content, this drill bit delivers outstanding performance in the most challenging materials. At this larger diameter, the superior heat resistance provided by the cobalt enrichment becomes especially valuable, allowing sustained drilling through thick sections of stainless steel, hardened alloys and high-temperature materials. The fully ground finish ensures optimal cutting geometry and efficient chip evacuation, whilst the 135° non-slip split point guarantees accurate centring and reduces drilling effort. Manufactured in accordance to DIN 388 standards for guaranteed
