Walter-titex 5058587 Jobber Length Drill Bit 11.5 Mm

Product Description

The WALTER-TITEX 5058587 is a jobber length drill bit designed for precision hole-making in cast iron and steel. Built from high speed steel with an oxide coating for added wear resistance, it features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust during entry. The straight-cylindrical shank measures 0.4528 inches in diameter, matching the 11.5 mm cutting diameter for a secure chuck grip. With a regular spiral flute and 2-flute geometry, this bit promotes efficient chip evacuation in both blind hole and stack drilling applications. It is suited for high-performance general purpose work and conforms to ANSI, ISO, BS, and DIN standards.

This drill bit is intended for use in ferrous materials, specifically cast iron and steel, across a range of machining and fabrication environments. Its jobber length profile and straight shank make it compatible with standard drill presses, CNC machining centers, and hand-held power drills commonly found in manufacturing, maintenance, and trade shop settings. The 8xD flute-to-diameter ratio and a maximum drilling depth of 2.992 inches support reliable performance in moderate-depth blind hole and stack drilling operations.

Installation Notes

Installation is performed by machinists and tool-and-die or maintenance technicians using standard drill presses, lathes, or CNC equipment. Secure the straight shank firmly in a keyed or keyless chuck before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Follow applicable shop safety procedures and machine guarding requirements when operating rotating tooling.
