Faithfull Professional HSS Jobber Drill Bit

The Faithfull Professional 12mm HSS Jobber Drill Bit is a versatile workhorse size commonly used for creating clearance holes for M12 fixings, cable entry points and general medium-to-heavy duty metalworking applications. This 12mm diameter strikes an excellent balance between hole size and structural strength. Constructed from M2 grade high-speed steel and fully ground to meet DIN 338 standards, this 12mm drill bit incorporates a 135° non-slip split point that bites immediately on contact, preventing drill wander and delivering precise hole placement without centre punching. The robust construction handles the demands of drilling through alloy steels, carbon steels, cast iron, hardened alloy steels and stainless steels with confidence. This 12mm size is particularly popular with steel fabricators, maintenance engineers and construction professionals for creating fixing holes in structural steelwork, machinery bases and heavy-duty brackets where reliable, accurate drilling is essential.
