@f4grx no this is the standard way to capture an O-ring. a square groove would allow it to fall out. the trick is to use the right parameters so it compresses the correct amount. and i'm pretty sure there's a clever trick to eke the tool into place without leaving a plunge hole.

@tubetime @f4grx You usually use sticky grease to avoid having it falling out. That's at least how I know it.

@tubetime @f4grx The plunge hole shows that they did this as fourth axis mill work instead of lathe work, as far as I can tell. This should be lathe work, I think, for a better sealing surface. Lack of knowledge of design for manufacture and process selection seems to jive with the overall collection of 🤦 here, as far as I (just a hobby machinist) can tell. If I'm wrong, I'd love to learn!

Adam the Machinist had a potentially relevant video recently that was talking about undercuts including plunge holes, but not about mill vs. lathe work:
