Engineered for maximum structural rigidity and exceptional wear resistance under intense thermal stress, the Guhring HSCO Cobalt Stub Drill Bit range is the definitive industrial choice for challenging, high-precision drilling. Manufactured to strict DIN 1897 specifications from premium Cobalt High-Speed Steel (commonly designated as HSS-Co), these heavy-duty short series twist drills feature a compact flute length that drastically minimizes tool deflection and flexing. This ultra-rigid profile makes them ideal for high-speed CNC machining, shallow hole drilling, and demanding applications in tough, abrasive, or work-hardening materials like stainless steel, titanium, high-tensile alloys, and heavy structural plates. Delivering crisp hole starting and reliable tool life, Guhring's cobalt stub series ensures optimal execution in rigorous manufacturing, fabrication, and engineering environments.
