Guhring 9006220051600 Cobalt Jobber Drill Bit 13/64 in

Product Description

The GUHRING 9006220051600 is a cobalt jobber length drill bit engineered for high-performance drilling applications in metalworking and fabrication environments. Built to DIN 338 standards, this bit features a 130-degree split point with web thinning for reduced thrust and cleaner entry. The parabolic flute geometry promotes efficient chip evacuation, making it well-suited for deeper holes without recutting chips. At 13/64 inches (0.2031 inches) in diameter with a 3-3/8 inch overall length and a 2-1/16 inch flute length, it handles a range of production and maintenance drilling tasks. Installation and use are handled by machinists, tool-and-die workers, HVAC fabricators, and maintenance technicians working in metal-intensive trades.

This drill bit is designed for use in aluminum and a range of non-ferrous and ferrous workpiece materials, including those classified under material codes K, N, and P. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. It is appropriate for general-purpose jobber drilling in both manual drill press and CNC machining center applications. The Series 622 designation places this bit in a high-performance cobalt product family intended for demanding production environments where tool life and hole quality matter.

Key Features

Compatibility

Designed as a DIN 338-compliant jobber length drill bit suitable for aluminum and other workpiece materials in K, N, and P material classification groups. Compatible with standard straight-shank drill chucks and collet systems accepting a 13/64 inch shank diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, hand drill, or CNC spindle with an appropriate chuck or collet. Ensure the workpiece is securely fixtured and the chuck is properly tightened before operation. Use cutting fluid appropriate for the workpiece material to extend tool life and maintain hole quality. Inspect the cutting edges before use and replace the bit if chipping or wear is evident.
