Yes -- the trick is not to use taps from a hardware store. Most of them are terrible, fit only for cleaning up existing threads. Buy a good (expensive, but worth it) name-brand tap from a place like MSC www.mscdirect.com or Travers www.travers.com or any of the other good industrial suppliers. You will be amazed at the difference.
