When designing a part with a undercut, engineers should adhere to the following:

Threaded reliefs where both the outer diameter and face require clearance.

The designation refers to a specific type of undercut (Freistich) used in mechanical engineering and technical drawing. din 509e06x02 exclusive

: Specifies a form intended for workpieces where the planar surface (shoulder) is not subjected to high fatigue loads and does not require special treatment. It is primarily used when the cylindrical surface may need further machining but the shoulder does not. : This value represents the of the undercut in millimeters. : This value represents the of the recess in millimeters. Key Specifications Description The curvature at the bottom of the groove. The penetration depth into the workpiece. Surface Roughness (Standard) Standard roughness is typically unless otherwise specified. Application Rotational Parts

In regulated markets, internal trigger mechanisms require thin rust prevention without changing the part's functional geometry (sear engagement surfaces). DIN 509E06X02 exclusive offers a dry-film lubricant that prevents carbon fouling adhesion. When designing a part with a undercut, engineers

📍 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.
