Tap/drill mini wizard
How about a sort of tap/drill mini wizard? You select a thread size, material, hole depth, and tap type (cutting or form). The wizard then gives you the proper drill size with feed/speed/peck depth, and the feed/speed for the tap. It would also be cool if the drill size selection would take account the hole depth, e.g. that deeper holes should use a lower percent thread engagement. A visual representation of thread engagement would be great too.
also include 8-40 and 6-48 taps thread data major and minor dia. for internal and external threads
Great idea. That makes one less table I have to look up. Particularly helpful for metric sizes, since I don't have those sizes memorized.
