Faithfull Professional HSS Jobber Drill Bit 11mm

The Faithfull Professional 11mm HSS Jobber Drill Bit is a popular size for creating clearance holes for M10 bolts and general medium-duty metalworking applications. This 11mm diameter provides the ideal clearance for metric fixings whilst maintaining structural integrity in the surrounding material. Constructed from M2 grade high-speed steel and fully ground to meet DIN 338 standards, this 11mm drill bit incorporates a 135° non-slip split point that bites immediately on contact, preventing drill wander and eliminating the need for centre punching. This professional-grade bit delivers consistent, reliable performance when drilling through alloy steels, carbon steels, cast iron, hardened alloy steels and stainless steels. The 11mm size is particularly valued by fabricators, fitters and maintenance engineers for creating accurately positioned fixing holes in structural steelwork, machinery mounting plates and general engineering applications.
