Guhring 9005300031000 Jobber Drill Bit 0.122in Firex Pm

Product Description

The GUHRING 9005300031000 is a jobber-length drill bit engineered for high-performance metal cutting in industrial and trade applications. Built from PM-ASP-60 powdered metal (PM) tool steel and coated with FIREX for extended wear resistance, this bit handles demanding materials including cast iron and steel. The 130-degree point angle with cone relief geometry and web-thinned, tapered web configuration improves penetration and reduces thrust load. With a parabolic flute design and a 5xD flute-to-diameter ratio, chip evacuation is efficient at typical jobber drilling depths. Machinists, tool-and-die tradespeople, and maintenance mechanics rely on this series for consistent, repeatable hole quality in production environments.

This drill bit is suited for drilling cast iron and steel workpieces in both shop and field maintenance settings. The straight-cylindrical shank fits standard drill chucks without adapters, making it compatible with drill presses, CNC machining centers, and handheld power tools. The 0.122-inch diameter targets precision pilot holes, tap drill applications, and close-tolerance through-holes where dimensional accuracy is critical. Conformance to DIN 338 standards means the geometry and tolerances align with internationally recognized tooling specifications used across manufacturing and fabrication trades.

Key Features

• PM-ASP-60 powdered metal construction for high hardness and heat resistance in ferrous materials
• FIREX coating reduces friction and extends tool life in abrasive cutting conditions
• 130-degree cone relief point with web thinning for reduced thrust and improved self-centering
• Parabolic flute geometry promotes efficient chip evacuation at depths up to 1.234 inches
• Straight-cylindrical shank fits standard drill chucks without modification
• Conforms to DIN 338 specification for consistent geometry and tolerance

Compatibility

Designed for drilling cast iron and steel workpieces. Primary workpiece material codes K and P per DIN classification. Fits any standard drill chuck accepting a 0.122-inch straight-cylindrical shank.

Installation Notes

This drill bit is installed and operated by machinists, maintenance mechanics, and metalworking tradespeople. Secure the straight shank firmly in a properly sized drill chuck before use and verify chuck runout is within acceptable limits to protect the bit and hole tolerance. Always wear appropriate PPE including eye protection when drilling metal. Follow the tooling manufacturer and machine operator guidelines for feed rate and spindle speed appropriate to the workpiece material and bit diameter.
