Callout: Hole Termination
Callout: Hole Termination
(OP)
I don't think this is defined in any standard, so I wanted to check here. I have a machined hole that requires a flat bottom, but I do not feel a section view is required for it. In the past I have used the counter-bore symbol to define a flat-bottomed hole without trouble.
My last employer/vendors had no problem with this method of call-out, QA/vendors at my current location are questioning this practice. Any suggestions?

I'd say "FLAT BOTTOM" or something if I really didn't want to put even a partial Xsection.

In some situations one would use the term counterbore, but in others they could be referred to as spotfaces, all depending on their purpose. I'll just replace the C'bore symbol with "FLAT BOTTOM".
