Thanks for this, Brian! I was tearing my hair out trying to figure out how to do a countersink in a hole. I'm still playing with the MoI demo (I really love this CAD software btw). I hope the developer of MoI (Michael) makes this into a proper feature in the new version as MoI is an excellent alternative to many of the other offerings available. Or perhaps someone would be so kind as to write a script that would do a countersink in a hole.

If you have a bunch to do then make a tool that cuts the hole and countersink in one shot using Boolean > Diff

That's an excellent tip. Thanks!
