Guhring 9006580032600 Cobalt Jobber Drill Bit Size 30

Product Description

The GUHRING 9006580032600 is a cobalt jobber-length drill bit in wire gauge size 30, with a decimal diameter of 0.1285 inches and a shank diameter of 0.1283 inches. It carries a Titanium Nitride (TiN) coating over a high-performance cobalt steel body, delivering extended wear resistance in demanding applications. The 130-degree split-point geometry and parabolic flute profile work together to reduce cutting force, improve chip evacuation, and maintain accuracy through the full drilling depth of 1.225 inches. This bit is built to DIN 338 standards and belongs to GUHRING Series 658, a line engineered for precision and tool life in production environments. Machinists, tool-and-die professionals, and maintenance technicians install this bit in standard drill chucks.

This bit is suited for drilling cast iron and steel in both light manufacturing and heavy-duty maintenance applications. The parabolic flute design and web-thinned, tapered web construction make it effective in materials that generate stringy or compacted chips. The straight-cylindrical shank fits conventional drill chucks and collet holders without modification. It is a single-piece, individually packaged bit appropriate for bench drill presses, CNC drilling centers, and hand-held power drills where dimensional accuracy and hole quality are required.

Key Features

• Cobalt construction with TiN coating for heat and wear resistance in ferrous materials
• 130-degree point angle reduces walking and improves self-centering on entry
• Parabolic flute geometry promotes efficient chip evacuation and reduces heat buildup
• Web-thinned, tapered web lowers thrust force and extends tool life
• DIN 338 standard compliance ensures dimensional consistency across replacements
• Straight-cylindrical shank fits standard drill chucks and collet systems without adapters

Compatibility

Designed for use in cast iron and steel workpieces as indicated by primary workpiece material codes K and P. Fits standard drill chucks and collet holders accepting a 0.1283-inch straight-cylindrical shank. Conforms to DIN 338 dimensional standards.

Installation Notes

Install in a clean, properly sized drill chuck or collet and verify runout before beginning a production run. Power down the machine and lock out the spindle before changing bits. Use cutting fluid or coolant appropriate to the workpiece material to manage heat, as coolant-through is not supported by this bit design. Follow shop safety standards and machine manufacturer guidelines for speed and feed selection based on the 0.1285-inch diameter.
