Guhring 9006220016100 Cobalt Jobber Drill Bit 0.0635 in

Product Description

The GUHRING 9006220016100 is a cobalt jobber-length drill bit built for high-performance drilling in demanding trade and industrial applications. It carries a 0.0635-inch diameter corresponding to wire gauge size 52 and features a 130-degree split-point angle for accurate self-starting entry without a center punch. The parabolic flute geometry promotes faster chip evacuation and reduces heat buildup during deep-hole drilling. With an overall length of 1-11/16 inches and a flute length of 25/32 inches, this bit fits standard drill chucks via its straight-cylindrical shank. The bright, uncoated cobalt construction provides inherent heat resistance suited to harder workpiece materials. It is manufactured to DIN 338 standards and carries a web-thinned, tapered web configuration for reduced thrust force.

This drill bit is designed for right-hand cutting in materials including aluminum, non-ferrous metals, and general-purpose structural materials classified under DIN material groups K, N, and P. It suits production-floor machinists, maintenance technicians, and tool-and-die professionals who require tight dimensional control on small-diameter holes. The parabolic flute design makes it especially effective in applications involving interrupted cuts or through-holes in stacked material. The two-flute configuration keeps chip load balanced at small diameters. This bit ships individually but carries a minimum order quantity of 10 units, making it well-suited for shop-stock replenishment.

Key Features

• Cobalt construction provides heat resistance for drilling harder and abrasive materials
• 130-degree drill point angle enables self-starting entry and reduces walking on curved or angled surfaces
• Parabolic flute geometry accelerates chip evacuation and reduces heat buildup in deep-hole applications
• Web-thinned tapered web reduces axial thrust force at the cutting edge
• Bright uncoated finish — no coating adhesion concerns when re-sharpening
• Manufactured to DIN 338 standard for consistent dimensional accuracy

Compatibility

Designed as a DIN 338-compliant jobber-length drill bit for use in standard drill chucks and CNC machining centers accepting straight-cylindrical shanks. Rated for primary workpiece materials in DIN groups K (cast materials), N (non-ferrous metals), and P (steel and general structural materials).

Installation Notes

Installation of this drill bit is performed by machinists and maintenance technicians using standard keyless or keyed drill chucks. Ensure the chuck is fully tightened and the shank is fully seated before starting a cut. Power down and de-energize any machine spindle before inserting or removing the bit. Do not exceed the manufacturer-rated RPM range for the material and bit diameter being drilled, and use appropriate cutting fluid where the workpiece material and application require it.
