Engineered for maximum endurance under severe thermal and mechanical stress, the Guhring HSCO TiN Coated Jobber Drill Bit range is built for high-volume production environment applications. Combining a premium Cobalt High-Speed Steel core (HSCO / HSS-Co) with a high-hardness Titanium Nitride (TiN) surface coating, these standard-length twist drills deliver exceptional red-hardness, ultra-low surface friction, and significantly extended tool life. Featuring a specialized heavy-duty geometry (typically a 130° split point), they are specifically optimized for superior performance when drilling through abrasive, tough, or hard-to-machine materials, including cast iron, stainless steel, high-tensile carbon steels, and demanding alloyed plates.
