Guhring 9006220047600 Cobalt Jobber Drill Bit 3/16 in

Product Description

The GUHRING 9006220047600 is a cobalt jobber length drill bit designed for high-performance metal cutting in professional and industrial applications. Built to DIN 338 standards, this 3/16 inch diameter bit features a 130-degree split point and a parabolic flute geometry that promotes fast chip evacuation and reduced heat buildup during drilling. The bright, uncoated finish is standard for cobalt tooling used in demanding materials. With an overall length of 3-3/8 inches and a 2-1/16 inch flute length, it fits standard drill chucks and magnetic drill presses used by machinists, pipefitters, and fabricators.

This bit is rated for use in aluminum, non-ferrous metals, and lower-alloy steels, as indicated by workpiece material codes K, N, and P. The straight-cylindrical shank seats securely in three-jaw chucks without slipping under torque. A maximum drilling depth of approximately 1.766 inches makes it well suited for through-hole drilling in plate stock, structural members, and fabricated assemblies. It is sold individually and is a common choice for trade professionals who require a reliable jobber-length cobalt bit in the 3/16 inch size.

Installation Notes

This drill bit is intended for use by machinists, fabricators, and trade professionals using standard drill presses, hand drills, or magnetic base drills. Secure the straight-cylindrical shank firmly in a three-jaw chuck before operation and verify speed settings are appropriate for the workpiece material and bit diameter. Always wear appropriate eye protection and follow shop safety procedures when drilling metal. Do not exceed the recommended maximum drilling depth of 1.766 inches without retracting to clear chips.
