Given its premium cost (typically 30–50% higher than standard 6µm nickel-chrome), where does this coating make economic sense?
While the DIN 509 standard offers a broad table of options (radii ranging from 0.1 to 1.6 mm or more), the E0.6x0.2 combination serves a niche, sometimes considered "exclusive," purpose. The 0.6 mm radius (
Understanding technical standards like is essential for precision engineering, particularly when designing shafts and bores that require grinding or specific assembly tolerances. The designation DIN 509 E0.6x0.2 refers to a specific type of relief groove (undercut)

mm) : Indicates the radial depth that the cutting tool penetrates below the ideal cylindrical surface of the workpiece. What Makes It "Exclusive"?
Choosing the specialized DIN 509E06x02 Exclusive offers several long-term benefits:
: The structural shape/form, dictating a single-surface radial relief plunge. 0.6 : The cutting tool edge radius ( ) forming the base of the groove. 0.2 : The precise radial depth ( ) into the shaft wall. Given its premium cost (typically 30–50% higher than
If you are looking for a physical object based on the code , it is most likely a precision shaft or a shoulder on a mechanical component that features a specific Undercut Type E, Width 0.6mm, Depth 0.2mm , ground to a finish of Ra 0.8 or finer (typical for DIN 509 applications).
It is a 0.6 mm wide, 0.2 mm deep flat-bottomed undercut with rounded edges, used primarily to clear the run-out of threads on a precision shaft.
Utilized in situations requiring lightweight yet extremely durable fasteners that adhere to strict material safety standards. The designation DIN 509 E0
When a mating component—such as a bearing, washer, or gear—is pressed onto a shaft, it must sit entirely flush against the locating shoulder. If a radius or burr remains at the corner, the mating part will stall prematurely. The E0.6x0.2 groove completely clears out that corner space, guaranteeing perfect axial seating.
If you are looking to purchase this specific component, it is advisable to check technical specifications from specialized suppliers to ensure the "Exclusive" enhancements meet your project's unique requirements. Share public link
