Faithfull Professional HSS Jobber Drill Bit

The Faithfull Professional 11mm HSS Jobber Drill Bit (140mm overall length) is supplied as a single bit, reflecting the specialised nature of this larger diameter. The 11mm size is commonly used for clearance holes for M10 fixings, larger mounting applications, and substantial metalworking tasks across engineering, fabrication, and construction sectors. Manufactured from premium M2 grade high-speed steel and fully ground to DIN 338 standard, this substantial drill bit is built to handle the significant cutting forces involved in larger diameter drilling. The 135° non-slip split point design is particularly advantageous at this size, providing immediate grip on the work surface and eliminating the bit wander that would otherwise compromise accuracy and potentially damage expensive workpieces. Designed for professional use in demanding environments, this drill bit cuts efficiently through alloy steels, carbon steels, cast iron, hardened alloy steels, and stainless steels, delivering reliable performance when you need it most.
