The GUHRING 9006580027000 is a cobalt jobber-length drill bit with a titanium nitride (TiN) coating, designed for high-performance drilling in cast iron and steel. It measures 2.7 mm (0.1063 inches) in diameter with a 2-13/32 inch overall length and features a 130-degree split point for accurate starting and reduced thrust. The parabolic flute geometry promotes efficient chip evacuation, and the web-thinned, tapered web configuration reduces cutting resistance. This bit is built to DIN 338 standards and carries a straight-cylindrical shank for use in standard drill chucks. It is suited for metalworking professionals operating in production or maintenance environments.
This drill bit is intended for drilling cast iron and steel in residential, commercial, and industrial maintenance applications. The Series 658 parabolic flute design is optimized for applications requiring deeper hole drilling with reduced chip packing. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 1.14 inches (28.95 mm), it handles through-holes and blind holes in moderate-thickness stock. Machinists, tool-and-die technicians, and maintenance trades rely on this bit for consistent hole quality in ferrous materials.
Designed as an OEM-grade replacement or direct-use drill bit compatible with any standard drill chuck accepting a 0.1063-inch straight-cylindrical shank. Primary workpiece materials are cast iron and steel, per DIN 338 Series 658 specifications.
This drill bit is installed and operated by machinists or maintenance technicians using drill presses, CNC drilling machines, or hand-held power drills equipped with a compatible chuck. Before chucking, inspect the shank for damage and confirm the chuck jaws are clean and properly tightened. Coolant-through capability is not available on this bit, so use an appropriate external cutting fluid when drilling steel to manage heat and prolong tool life. Do not exceed the recommended maximum drilling depth of 1.14 inches per pass without retracting to clear chips.
