One specific, highly precise variant used in specialized applications is the , a type E undercut designated under the DIN 509 standard. While DIN 509 defines various forms, the "E0.6x0.2" designation is often treated as an exclusive choice for specific, high-precision, or space-constrained requirements.
This guide explores the technical, design, and manufacturing aspects of this specific undercut type. What is DIN 509 E0.6x0.2?
: The foundational engineering standard defining the forms, dimensioning rules, and application criteria for relief grooves on turned parts and internal bores.
📍 It removes the small "fillet" left by cutting tools. This ensures a sharp corner so a bearing or washer can slide completely against the shoulder. din 509e06x02 exclusive
By breaking down this technical shorthand, engineers can ensure perfect component assembly, reduce stress concentration points, and optimize CNC machining workflows. Anatomy of the Designation: What Does It Mean?
A Type E undercut is characterized by its single-sided relief. Unlike Type F, which provides relief for both the cylindrical and planar surfaces, Type E focuses on clearing the corner to allow a mating part with a counterbore to fit perfectly.

For this specific size, the standard typically specifies the following additional dimensions to ensure proper tool clearance: Value (mm) Depth Breadth (Width) Run-out Angle 15° (Standard for Type E) Application Guidelines Workpiece Diameter ( One specific, highly precise variant used in specialized
Use dedicated turning tools designed for E-type grooves with a corresponding 0.6 mm tip radius.
The keyword "DIN 509E06X02 exclusive" deviates from this norm, introducing custom modifiers that signal a proprietary or highly specialized batch.
For superior corrosion resistance in automotive applications. What is DIN 509 E0
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).
Let's decode it step by step according to the DIN 509 standard (Electrodeposited coatings):
