Let’s dissect DIN 509E06X02 :
The standard represents the intersection of German engineering precision and modern chemical innovation. It is not for every part—its 6µm thickness requires pristine substrate quality and its exclusivity demands a supply chain partnership. However, for critical fasteners, pneumatic valves, and EV components requiring galling protection, uniform matte appearance, and chemical resistance, it is unmatched.

Following the "x," the value 0.2 denotes the depth (t) of the cut, also measured in millimeters. This is the vertical distance from the original surface of the shaft down to the bottom of the groove. For a 0.6 mm radius, a depth of 0.2 mm is standard. This shallow depth ensures structural integrity is maintained while providing just enough clearance for a grinding wheel or threading tool to run out. It is important to note that while the "0.6 mm" refers to the radius (the curve), the "0.2 mm" refers to the depth . Some applications may refer to a simplified notation like "DIN 509-E1x0,2," where the "1" refers to a larger radius of 1 mm; however, "E06X02" specifically indicates the smaller, more fine-detail undercut of 0.6mm radius.

Here is the decoding of the specification:
mm) : Indicates the radial depth that the cutting tool penetrates below the ideal cylindrical surface of the workpiece. What Makes It "Exclusive"? We currently have a of DIN 509E06X02 Exclusive available

According to standard DIN 509 manufacturing documentation , the profile follows a rigid mathematical and spatial matrix: Metric Parameter Value / Dimension Engineering Application Tool Nose Radius ( ) Determines the curvature of the inner corner fillet. Groove Depth ( ) Establishes the tool penetration depth below the cylinder. Minimum Runout Length ( ) Total width of the undercut along the shaft axis. Recommended Shaft Dia.
