The designation refers to a specific type of relief groove (also called an undercut) used in mechanical engineering for turned parts and bores. These grooves provide clearance for subsequent machining tools (like grinding wheels) and ensure mating parts can sit flush against a shoulder. Specification Details
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.

By intentionally cutting a minor recess into the corner, the designer ensures that the mating part makes uniform contact across the vertical face of the shoulder. 2. Decoding the Nomenclature: DIN 509 E0.6x0.2 din 509e06x02 exclusive
