Guhring 9006220012000 Cobalt Jobber Drill Bit 1.2 Mm

Product Description

The GUHRING 9006220012000 is a cobalt jobber length drill bit engineered for high-performance drilling in a range of materials. Sized at 1.2 mm (0.0472 inches) in diameter, this bit features a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduces heat buildup at the cutting edge. The bright, uncoated cobalt construction delivers the hardness and heat resistance needed for demanding applications. With an overall length of 1.5 inches and a flute length of 0.625 inches, the 9006220012000 is built to DIN 338 standards and is suitable for professional machining and fabrication environments where tight tolerances and repeatable performance are required.

This drill bit is designed primarily for use on aluminum and similar non-ferrous and general-purpose materials, corresponding to workpiece material codes K, N, and P. The right-hand cut and web-thinned, tapered web configuration make it well suited for CNC drilling operations and manual drill press setups in production, toolroom, and job-shop environments. A maximum drilling depth of 0.559 inches (14.2 mm) makes it appropriate for through-hole and shallow blind-hole applications at this diameter range. It ships individually but is available in minimum order quantities of 10 units, making it practical for stocking in trade and production settings.

Key Features

• Cobalt construction provides increased hardness and heat resistance compared to standard HSS bits
• 130-degree point angle with web-thinned, tapered web for reduced thrust and improved centering
• Parabolic flute design promotes fast, efficient chip removal and reduces chip re-cutting
• Bright, uncoated finish suitable for use with cutting fluids and coolants
• Straight-cylindrical shank at 0.0472 inches diameter for standard collet and chuck compatibility
• Manufactured to DIN 338 specification for consistent dimensional accuracy across production runs

Compatibility

Designed as an OEM-style replacement and production-grade drill bit for use in standard jobber-length drill applications conforming to DIN 338. Suitable for workpiece materials classified under codes K, N, and P, including aluminum and general-purpose materials, as specified in the product data.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with drilling operations. Ensure the workpiece is securely clamped and the drill press or CNC spindle is de-energized before loading or changing bits. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain dimensional accuracy. Do not exceed the maximum recommended drilling depth of 0.559 inches for this diameter without retracting to clear chips.
