Every character in the standard designation provides explicit geometric instructions to the machinist:
In industry jargon, "exclusive" means you are not buying a commodity plating job; you are buying a certified, value-added process with documented traceability.
used in technical drawings and machining to provide clearance at the transition between a cylindrical surface and a shoulder. Technical Specifications for E 0,6 x 0,2 According to the DIN 509:2006-12 standard , the parameters for this specific undercut are: din 509e06x02 exclusive
DIN 509 defines four specific geometric configurations for relief grooves, known as Forms E, F, G, and H. The designation "E" refers specifically to the radial undercut . Unlike other forms that combine axial and radial cuts for grinding vertical walls, Form E is designed exclusively for cylindrical surfaces where only the lateral (outer) surface requires further processing. Think of a shaft that needs to be slid into a bearing or a hydraulic piston. The "E" undercut creates a rounded transition at the base of the shoulder, eliminating a sharp 90-degree corner which would otherwise act as a stress riser, potentially leading to metal fatigue and failure.
The term "Exclusive" is not an official part of any DIN standard. Therefore, a designation with this word is almost certainly a . It likely represents: The designation "E" refers specifically to the radial
Standard roughness for these surfaces is typically ), though tighter tolerances like can be specified in the drawing.
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 The "E" undercut creates a rounded transition at

As an engineer, specifying "DIN 509E06X02 exclusive" is a powerful way to lock in performance without writing a 5-page custom specification. It tells the supplier: "Do not substitute. Do not mass-barrel. I need the certified, low-friction, high-corrosion thin film."
The keyword represents a highly specific, precise technical designation within precision engineering, manufacturing, and computer-aided design (CAD). At its core, this string references an engineered relief groove or undercut designed according to the widely adopted German standard, DIN 509 .
