Guhring 9006220047000 Cobalt Jobber Drill Bit No 13

Product Description

The GUHRING 9006220047000 is a cobalt jobber length drill bit designed for demanding drilling applications in metal and non-ferrous materials. Sized to wire gauge No. 13 (0.1850 inches decimal), it features a 130-degree split point angle and a parabolic flute geometry that promotes efficient chip evacuation and reduces heat buildup during prolonged drilling cycles. The straight-cylindrical shank measures 0.1850 inches in diameter, making it compatible with standard drill chucks. Built to DIN 338 specifications, this is a high-performance drill bit intended for use by machinists, maintenance technicians, and fabricators working with aluminum, plastics, and ferrous workpiece materials.

This drill bit is suited for jobber-length drilling in light to medium production environments. Its parabolic flute design and web-thinned point are particularly effective in aluminum and similar non-ferrous materials, as well as general-purpose steel applications. The bright uncoated finish is appropriate for dry drilling or use with cutting fluid. A right-hand cutting direction means it runs with standard clockwise-rotation drilling equipment. The Series 622 designation places it within GUHRING high-performance cobalt tooling, conforming to DIN 338 standards commonly specified in aerospace, automotive, and general metalworking shops.

Compatibility

Designed as an OEM-style jobber length drill bit conforming to DIN 338 for use in standard straight-shank drill chucks; compatible workpiece material codes K, N, and P cover aluminum, non-ferrous metals, and general-purpose steels as specified in the product attributes.

Installation Notes

This drill bit should be installed and operated by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation and verify chuck runout is within acceptable tolerance to avoid premature wear. Power down and de-energize all drilling equipment before changing tooling. Always use appropriate cutting fluid or dry-drilling technique as required by the workpiece material to maintain tool life and surface finish quality.
