Guhring 9006580010200 Cobalt Drill Bit No. 60 Series 658

Product Description

The GUHRING 9006580010200 is a jobber-length drill bit engineered for high-performance drilling in ferrous metals and cast iron. Built from cobalt high-speed steel and finished with a titanium nitride (TiN) coating, it delivers extended tool life in abrasive and work-hardening materials. The bit measures 0.0402 inches in diameter (No. 60 wire gauge) with a 130-degree split point and a parabolic flute designed to clear chips efficiently in deep-hole applications. At 1-11/32 inches overall length with a 15/32-inch flute, this is a precision cutting tool suited to machining operations, fabrication shops, and maintenance trades where accuracy in small-diameter holes is critical.

This drill bit is intended for right-hand cutting in steel and cast iron workpieces, classified under primary workpiece material codes K and P per DIN 338 standards. The parabolic flute geometry with a 5xD flute-to-diameter ratio supports deeper drilling relative to bit diameter while maintaining chip evacuation. The web-thinned, tapered web reduces entry resistance and improves centering on hard materials. Typical applications include precision hole drilling in structural steel, cast iron components, and general machining work requiring tight dimensional control in small-gauge sizes. Sold individually with a minimum order quantity of 10 units.

Key Features

• Cobalt high-speed steel construction for heat resistance in abrasive ferrous materials
• Titanium nitride (TiN) coating extends surface hardness and reduces friction during cutting
• 130-degree standard point angle provides aggressive penetration in steel and cast iron
• Parabolic flute with 5xD ratio improves chip evacuation in deeper hole applications
• Web-thinned tapered web reduces cutting force and improves point stability on entry
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Manufactured to DIN 338 specification for consistent dimensional tolerances

Compatibility

Designed for use in steel and cast iron workpieces per DIN 338 Series 658 specification. Suitable for use with standard drill chucks or collet systems accepting a 0.0402-inch straight-cylindrical shank diameter.

Installation Notes

Installation and use of this bit is performed by machinists, tool-and-die professionals, and maintenance technicians operating drill presses, CNC machining centers, or hand-held power drills. Secure the straight-cylindrical shank firmly in the chuck or collet before operation and verify runout is within acceptable limits for the application. Coolant-through is not supported on this bit; use surface-applied cutting fluid when drilling steel or cast iron to manage heat buildup. Inspect the cutting edges and TiN coating for wear before each use and replace when diameter tolerance or point geometry is compromised.
