Din 509e06x02 Exclusive Jun 2026

Search for: “DIN 509 part 1 (1974)” or “DIN 50900” – but note it’s withdrawn and for historical reference only.

Refers to a relief groove with a specific geometry designed for parts where a shoulder meets a cylindrical surface. 0.6: Represents the radius ( ) of the tool relief groove in millimeters (0.6 mm). 0.2: Represents the depth ( ) of the undercut in millimeters (0.2 mm).

What makes different from standard DIN 509E06X02? The base standard defines a 6µm nickel-chromium layer. However, the "exclusive" suffix implies one or more of the following enhancements:

geometry is typically recommended for relatively small, precision workpieces with nominal shaft diameters ( ) ranging between . Why the E06x02 Geometry is Critical din 509e06x02 exclusive

If you are writing a specification or manufacturing to this old code:

: Using these exact dimensions reduces the variety of tools needed in a workshop, as specified in the DIN 509:2006-12 technical documentation . Visualizing the Undercut

An part—presumably a high-performance automotive or aerospace component—would likely require a superior finish. Achieving a smooth 0.6mm radius with a depth of 0.2mm requires specialized "grooving" or "undercutting" inserts with extremely precise nose radii. Mass-produced parts may skip this undercut altogether to save 2 seconds of machining time; an exclusive part includes it, ensuring the shaft seats perfectly flush against its mating component without binding on a sharp internal corner.

The drawing must indicate the full designation— Undercut DIN 509 — E0.6x0.2 .

are determined by the table in the standard for given diameters.) 4. Key Applications

The dimensional accuracy of the 06x02 specifications is maintained at a tighter tolerance (e.g., However, the "exclusive" suffix implies one or more

These grooves provide essential clearance for cutting tools (like thread cutters or grinding wheels) to finish their operation without damaging the workpiece. This creates a defined space that ensures:

: A specific form of undercut designed for workpieces where the planar surface (the shoulder) is not subjected to high fatigue loads and only the cylindrical surface may need subsequent machining. 0.6 x 0.2 : The specific dimensions of the undercut: Radius (r) : . Depth ( ) : . Why "Paper"?

. This specific combination is often chosen to balance structural integrity with manufacturing efficiency in smaller or medium-sized components. 2. Why "E0.6x0.2" is Considered "Exclusive"

The distance the cut penetrates beneath the finish diameter. Recommended diameter range for normal stress loads. Surface Roughness ( Racap R sub a ) (Standard) / Arithmetical mean deviation for the finished groove floor. Max Profile Height ( Rmaxcap R sub m a x end-sub ) (Standard) / Peak-to-valley roughness control to limit stress raisers. Structural Purpose and Advantages
