Faithfull Professional HSS Jobber Drill Bit

The Faithfull Professional 11.5mm HSS Jobber Drill Bit (142mm overall length) is supplied as a single bit, perfect for specialist applications requiring this specific intermediate size. The 11.5mm diameter is particularly valuable in precision engineering contexts where standard sizes don't provide the exact clearance or fit required, or when preparing holes for reaming operations. Constructed from high-quality M2 grade high-speed steel and precision ground to comply with DIN 338 standards, this drill bit offers exceptional performance and durability. The 135° non-slip split point provides crucial starting accuracy at this larger diameter, biting immediately into the material and maintaining precise positioning throughout the drilling operation. This professional-grade drill bit is engineered to handle the toughest metalworking challenges, cutting effectively through alloy steels, carbon steels, cast iron, hardened alloy steels, and stainless steels with consistent, reliable results.
