Faithfull Professional HSS Jobber Drill Bit

The Faithfull Professional 12mm HSS Jobber Drill Bit (150mm overall length) is supplied as a single bit, suitable for regular but not constant use of this substantial diameter. The 12mm size is widely employed for larger clearance holes, mounting bolt preparations, substantial fabrication work, and general heavy-duty metalworking applications. Manufactured from premium M2 grade high-speed steel and fully ground to meet the exacting DIN 338 standard, this robust drill bit is engineered to withstand the considerable torque and cutting forces associated with larger diameter drilling. The 135° non-slip split point is essential at this size, providing immediate purchase on even challenging surfaces and preventing the costly damage that can result from bit wander on larger drilling operations. Designed for professional tradespeople and serious metalworkers, this drill bit handles demanding materials with confidence, cutting cleanly through alloy steels, carbon steels, cast iron, hardened alloy steels, and stainless steels.
