This 13mm Faithfull Professional Cobalt Jobber Drill Bit is supplied as a single unit, representing the largest diameter in this professional range. The 13mm size is ideal for substantial drilling operations including heavy mounting bolts, large dowels and structural fixings in steel fabrication, heavy engineering and industrial maintenance applications. Manufactured from premium M35 HSSE grade steel with 5% cobalt content, this bit offers exceptional performance and durability when working with the most demanding materials. At this maximum diameter, the cobalt additive is essential for providing superior heat resistance and maintaining cutting efficiency during extended drilling operations in thick sections of stainless steel and hardened alloys. Featuring a fully ground construction and precision 135° non-slip split point, this drill bit ensures accurate centring even on curved or uneven surfaces. The split point design significantly reduces the force required to start holes in hard materials. Produced to DIN 388 standards for guaranteed high precision tolerances and geometric accuracy. Perfect for alloy steels, carbon steels, cast iron, hardened alloy steels, stainless steels, high temperature alloys, titanium alloy, high strength steel and carbon fibre composite materials. Features and Benefits: • Maximum 13mm diameter supplied individually • 5% cobalt for superior heat resistance • Fully ground for optimal cutting performance • 135° split point reduces drilling effort • DIN 388 compliant precision manufacture Specifications: Tip Diameter (mm): 13.0 Overall Length (mm): 151 Pack Qty.: 1 Diameter: 13.0mm.
