Guhring 9006220032600 Cobalt Jobber Drill Bit 0.1285 in

Product Description

The GUHRING 9006220032600 is a cobalt jobber length drill bit designed for high-performance drilling in demanding shop and field applications. Built to DIN 338 specifications, this bit features a 0.1285-inch diameter (Wire Size 30), a 130-degree standard point angle, and a parabolic flute geometry that improves chip evacuation and reduces heat buildup at depth. The bright, uncoated cobalt construction provides solid hardness and heat resistance without a coating that can chip or flake under hard use. A web-thinned, tapered web reduces entry resistance and allows cleaner starts on flat and curved surfaces. Licensed machinists, tool-and-die technicians, and maintenance tradespeople will find this bit well-suited for precision work where hole tolerance and finish matter.

This bit is built to suit aluminum, non-ferrous metals, and low-alloy steels, reflecting its Primary Workpiece Material codes K, N, and P. The straight-cylindrical shank fits standard drill chucks and collet systems without adapters, making it a drop-in choice for drill presses, CNC machining centers, and hand-held power drills across both production and maintenance environments. The two-flute, right-hand cut design is the standard configuration for general-purpose hole-making in these material families. Overall length is 2-9/16 inches, keeping the bit compact and rigid for its diameter class.

Key Features

• Cobalt construction for elevated heat resistance and edge retention in non-ferrous and light-alloy materials
• 130-degree standard point angle reduces walking and suits a wide range of workpiece materials
• Parabolic flute profile accelerates chip removal and reduces packing in deeper holes
• Web-thinned tapered web lowers thrust requirements and improves hole entry performance
• Bright uncoated finish maintains consistent diameter tolerance from minus 0.018 to 0.000 mm
• DIN 338 specification ensures dimensional conformance for interchangeable tooling applications

Compatibility

Designed as a DIN 338 Series 622 jobber length drill bit compatible with standard straight-shank drill chucks and collet holders accepting a 0.1285-inch shank; suited for CNC machining centers, drill presses, and portable drilling equipment used on aluminum, non-ferrous metals, and low-alloy steel workpieces.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance tradespeople familiar with proper drill chuck seating and workpiece fixturing. Secure the workpiece fully before drilling to prevent rotation and bit breakage at this small diameter. Power down and de-energize or lock out any machine before changing tooling. Do not exceed the machine spindle speed rating for this diameter and material combination; consult the machine manufacturer and tooling data for appropriate feed and speed parameters.
