Faithfull Professional HSS Jobber Drill Bit

The Faithfull Professional 12.5mm HSS Jobber Drill Bit (150mm overall length) is supplied as a single bit, ideal for specific engineering and fabrication applications. The 12.5mm diameter is particularly useful for creating precise holes where standard imperial or metric sizes don't provide the exact clearance required, or when preparing holes for subsequent machining operations. Crafted from high-quality M2 grade high-speed steel and precision ground to DIN 338 standard, this substantial drill bit combines durability with cutting efficiency. The 135° non-slip split point design is particularly valuable at this larger diameter, ensuring the bit grips immediately on contact and maintains accurate positioning throughout the drilling operation, even on curved or angled surfaces. This professional-grade drill bit is built to handle the most demanding metalworking tasks, cutting effectively through alloy steels, carbon steels, cast iron, hardened alloy steels, and stainless steels with consistent performance.
