.If I pilot drill a hole and slow (low RPM)plunge cut with a .750 four flute new end mill on a tight Bridgeport, what diameter can I expect?

There is no stupid or any disrespect here as we all think things others may think elsewhere.Being stupid. I should not have replied to the thread.

Thank you all for the responses. Guess I'll bore it. It just seemed like I might have got lucky. The sized hole called out is .751 +0.001/-0.000. I would have probably jig bored or jig ground if I was at my old shop. I'll be lucky if I can bore it to that spec.
You're welcome... but a little FYI for future reference. You've really wasted a lot of people's time and efforts in this post by stating here well after the fact that you had a plus one tolerance on your hole. For all practical purposes that tolerance makes your initial or original post irrelevant. Meaning something like you were after wouldn't even be considered in this situation so why ask?
Get smart. State you case precisely form the beginning. This is a precise business we're all in. Generalities spoken around one thou tolerances are practically meaningless.

Sorry you feel that way Dave. I don't think I wasted anyone's time. I got a lot of valuable information from this post that I can use in the future. The tolerance of the hole was irrelevant. My original question was "If I pilot drill a hole and slow (low RPM)plunge cut with a .750 four flute new end mill on a tight Bridgeport, what diameter can I expect? ". I was wanting that knowledge to use in the future not just for a single job. Thanks everyone. I learned some things.
