Faithfull Professional HSS Jobber Drill Bit 13mm

The Faithfull Professional 13mm HSS Jobber Drill Bit is the largest diameter in this comprehensive range, designed for heavy-duty metalworking applications requiring substantial holes. This 13mm bit is ideal for creating clearance holes for M12 fixings with generous tolerance, cable entry points, and structural fabrication work. Constructed from robust M2 grade high-speed steel and fully ground to meet DIN 338 standards, this 13mm drill bit incorporates a 135° non-slip split point that provides immediate bite and prevents drill wander, ensuring accurate hole placement even on challenging surfaces. The premium manufacturing process ensures this larger diameter bit can handle the increased torque and heat generated when drilling through alloy steels, carbon steels, cast iron, hardened alloy steels and stainless steels. This 13mm size is particularly valued by structural steel fabricators, heavy engineering professionals and maintenance teams working with industrial machinery where larger, accurately positioned holes are required.
