How to select the right tap for a #3-48 UNC thread?
For a #3-48 UNC thread, use a three-piece hand tap set like the WIDIA GTD 15159. Start with the taper tap for easy alignment, then the plug tap for deeper threads, and finish with the bottoming tap for threads close to the hole bottom. Always use cutting fluid and turn the tap 1/2 turn forward, then 1/4 turn back to break chips.
