Faithfull Professional HSS Jobber Drill Bit

The Faithfull Professional 13mm HSS Jobber Drill Bit (150mm overall length) is supplied as a single bit, representing one of the larger sizes in this professional range. The 13mm diameter is essential for substantial fixings, large clearance holes, heavy fabrication work, and demanding metalworking applications where significant material removal is required. Manufactured from premium M2 grade high-speed steel and fully ground to meet DIN 338 standards, this robust drill bit is engineered to handle the considerable forces involved in large diameter drilling operations. The 135° non-slip split point is crucial at this size, providing immediate bite into the material and preventing the potentially dangerous bit wander that can occur with larger conventional drill bits. Designed for professional use in demanding industrial and fabrication environments, this drill bit cuts efficiently through alloy steels, carbon steels, cast iron, hardened alloy steels, and stainless steels, delivering reliable performance on the toughest jobs.
