Guhring 9055200060000 Cobalt Stub Drill Bit 6mm

Product Description

The GUHRING 9055200060000 is a cobalt screw machine (stub) length drill bit designed for precision drilling in metalworking and light industrial applications. Built to DIN 1897 standards, this bit measures 6.00 mm (0.2362 inches) in diameter with a 118-degree four-facet split point and a web-thinned, tapered web configuration for reduced thrust and accurate entry. The two-flute spiral design with a straight-cylindrical shank handles demanding drilling operations where stub-length rigidity is essential. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the primary users of this type of tooling.

This bit is suited for production drilling in aluminum and similar non-ferrous and softer ferrous workpiece materials. The stub length format provides extra rigidity in applications where drill deflection is a concern, such as short-entry holes, fixture work, and screw machine operations. The cobalt construction offers heat resistance above standard high-speed steel, making it appropriate for higher-speed cuts or interrupted cuts where tool temperature can rise quickly.

Key Features

• Cobalt tool material for elevated heat and wear resistance compared to standard HSS
• 118-degree four-facet split point with web thinning for fast, accurate hole entry and reduced walking
• Stub (screw machine) length for maximum rigidity and minimal deflection
• Two-flute regular spiral design for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Manufactured to DIN 1897 specification

Compatibility

Designed as an OEM-style replacement or production tooling option for applications requiring a 6.00 mm cobalt stub-length drill bit conforming to DIN 1897.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank fully in a drill chuck or collet before operation and verify runout is within acceptable tolerance. Always power down and de-energize the machine before changing tooling. Do not exceed the recommended drilling depth of 0.7480 inches (19.00 mm) for this stub-length bit.
