2 inch NPT Thread milling

[sureline67]

Can anyone walk me through on how to thread mill a 2 inch NPT?

Put the npt angle under the taper setting. 

 

You can use a single point tool or you can get an inserted one with npt inserts

NPT Threadmills are nice because it will cut the taper for you. I always measure the gage for the thread to give me a rough idea of the diameter size I need to interpolate. I also measure the threadmill diameter on an optical comparator @ the depth ill be dropping the threadmill into the hole. Usually this will get me within .005 of where I need to be for the flat on the gage to land right. Then I just walk it in using cutter comp.

Look at the Advent integrated ones if doing production work. If one or two parts then a Carmex threadmill should do the trick.

That's pretty slick! I've always used the Vardex wizard, but this one is faster and easier.
