Which causes me to wonder why die makers go to the trouble of cutting dies with a fancy reamer.[/quote]
If your question is truly for discussion, here is my opinion. Reamers are used for accuracy, speed and repeatability. A reamer only takes 1/10 of the time to use as it would take to bore the die in a lathe and every one would be the same. Boring is OK for a one-off such as the OP’s application.
