If you have a precision ground cutter it should be close to the worm pd. Some unground cutters I've had are quite a bit oversize with a large amount of back-off which would shorten the life dramatically. I have had great results with TiCn coating and Lazer 964 over it giving me 5 times life over uncoated. I was cutting inconel at RC 32.
