Guhring 9006580047600 Cobalt Drill Bit 3/16 in Series 658

Product Description

The GUHRING 9006580047600 is a cobalt jobber length drill bit designed for demanding metal drilling applications in professional trade and industrial environments. Built to DIN 338 standards, this 3/16 inch diameter bit features a titanium nitride (TiN) coating over a cobalt steel body, delivering extended tool life when cutting through cast iron and steel. The 130-degree split point and parabolic flute geometry reduce thrust, improve chip evacuation, and minimize walking on entry. Machining professionals, maintenance mechanics, and metalworkers rely on this bit where standard high-speed steel tooling falls short.

This drill bit is suited for production and maintenance drilling in residential, commercial, and industrial settings. It performs in materials coded K and P under ISO material classification, covering cast iron and carbon and alloy steels. The straight-cylindrical shank seats securely in standard drill chucks and drill press spindles. The parabolic flute design handles deeper holes without chip packing, making it effective for structural steel fabrication, equipment repair, and precision metalwork.

Key Features

• Cobalt steel construction with TiN coating for heat resistance and extended wear life
• 130-degree point angle with web-thinned, tapered web for reduced entry thrust and self-centering starts
• Parabolic flute profile improves chip flow and supports a 5xD flute-to-diameter ratio
• Right-hand cut with straight-cylindrical shank for compatibility with standard drill chucks
• Conforms to DIN 338 specification for consistent dimensional tolerances
• Rated for cast iron and steel primary workpiece materials

Compatibility

Designed as an OEM-grade replacement or direct-application drill bit for use in any standard drill chuck or drill press accepting a 3/16 inch straight-cylindrical shank, conforming to DIN 338 dimensional standards.

Installation Notes

This bit is installed by a machinist or qualified metalworker using a keyed or keyless drill chuck on a handheld drill or drill press. Ensure the chuck is fully tightened and the workpiece is secured before drilling. Use appropriate cutting fluid or coolant when drilling steel to manage heat buildup, particularly at higher spindle speeds. Do not exceed the rated maximum drilling depth of 1.766 inches in a single pass without clearing chips.
