Many times a brass insert is cut with the inverted flare seat and pressed into a bored recess in the part. I know that master cylinders are made that way. That type of part can be made on a lathe.

How many of these parts are you making?

If you are doing a bunch, like Dugg said, a custom cutter may be the way to go.

You'd try one of these guys who do custom tooling.

( I never used these particular people, I just googled "custom tooling"

Here is a company I found that made a tool called a "cone cutter", this one is a 10* but it looks like it's the right idea.


IIRC, rutland and enco offer custom services as well.

my signature lines...not really directed at anyone in particular..

BE different....ACT normal.

No one is completely useless..They can always be used as a bad example
