Guhring 9006580020800 Cobalt Jobber Drill No 45

Product Description

The GUHRING 9006580020800 is a cobalt jobber-length drill bit in No. 45 wire size (0.0820 inches diameter), designed for demanding drilling applications in steel and cast iron. Built to DIN 338 standards, this heavy-duty bit features a 130-degree point angle that reduces thrust force and improves centering on entry. A titanium nitride (TiN) coating increases surface hardness and extends tool life in abrasive materials. The parabolic flute geometry promotes faster chip evacuation, making it well suited for production drilling where cycle time matters. It is used by machinists, tool and die techs, and maintenance professionals working with ferrous metals.

This drill bit is intended for use in steel and cast iron, including both wrought and cast ferrous workpieces classified under material codes K and P. At 1-15/16 inches overall length with a 15/16-inch flute length, it fits standard drill chucks and is sized for close-tolerance work requiring a No. 45 wire gauge hole. The straight cylindrical shank seats securely in keyed or keyless chucks on benchtop drill presses, CNC machining centers, or handheld power drills. A web-thinned, tapered-web design reduces the chisel edge load at entry.

Key Features

• Cobalt high-speed steel construction for heat and wear resistance in ferrous materials
• TiN coating increases surface hardness and reduces friction during cutting
• 130-degree split point angle for self-centering entry and reduced thrust
• Parabolic flute profile accelerates chip removal and reduces clogging
• Web-thinned tapered web lowers cutting force at the chisel edge
• Built to DIN 338 standard for consistent dimensional tolerances

Compatibility

Designed as an OEM-specification replacement or direct-use jobber drill for applications requiring a No. 45 wire size hole in steel and cast iron workpieces per DIN 338 Series 658.

Installation Notes

Install in a drill chuck rated for straight-shank tooling and confirm the shank is fully seated before applying power. Secure the workpiece firmly before drilling to prevent walking or deflection. Use appropriate cutting fluid or coolant for ferrous materials to manage heat buildup, as this bit does not support through-coolant delivery. Inspect the cutting edges for wear before each use; cobalt bits can chip if run at incorrect speeds for the workpiece material.
