Guhring 9005300022600 Jobber Drill Bit 0.0890 in Firex

Product Description

The GUHRING 9005300022600 is a jobber-length drill bit engineered for high-performance drilling in ferrous materials. It measures 0.0890 inches in diameter and carries a wire gauge designation of #43. The bit is manufactured from powdered metal and finished with a FIREX multi-layer proprietary coating designed to extend tool life in demanding cutting applications. The 130-degree point angle and parabolic flute geometry promote fast chip evacuation and reduced heat buildup. Overall length is 2.0900 inches with a flute length of 1.0600 inches. This bit is intended for use by machinists, maintenance technicians, and toolroom professionals working on precision drilling tasks.

This drill bit is suited for production and maintenance drilling operations in steel, cast iron, and stainless steel workpieces. The parabolic flute design with a fast spiral type makes it effective in deeper holes where chip packing is a concern. The straight cylindrical shank fits standard drill chucks used in benchtop drill presses, CNC machining centers, and handheld power tools. Maximum drilling depth is 0.9300 inches. The Series 530 designation follows DIN 338 standards, making it a recognized specification in industrial tooling environments.

Installation Notes

Install in a properly sized and tightened drill chuck before use. Ensure the drilling machine spindle speed is appropriate for the workpiece material and bit diameter before starting the cut. Secure the workpiece firmly to prevent movement during drilling. Inspect the cutting edges for wear or chipping before each use and replace if edge condition is degraded.
