Engineered for maximum torsional rigidity and high-feed performance in larger-diameter applications, the Guhring HSS TiN Coated Stub Drill Bit range (9.7mm to 14.0mm) is built for heavy-duty industrial tasks. Manufactured to strict DIN 1897 specifications, these premium large-diameter short series twist drills feature a compact flute length that drastically reduces tool deflection and twisting forces under heavy load. The working tip is enhanced with a premium Titanium Nitride (TiN) coating, which dramatically reduces surface friction, dissipates intense localized heat, and preserves sharp cutting edges. This makes these bits ideal for repetitive, high-torque operations in automated CNC machining centers cutting through structural steels, cast iron, alloyed plates, and tough fabrication components.
