You can, absolutely, drill a hole for an NPT thread. You don't need to bore or circular interpolate a tapered bore first. The only caveat is that you use an NPT thread mill, which has the required minor diameter taper ground on it, as well as the tapered threads. FWIW, you can also purchase a tapered reamer that would taper that hole much faster than an endmill.
Another great tip. Just a thought: sometime an NPS thread + an O ring can achieve just as good a seal. And tape or sealant is still needed with NPT threads. Though I think in your case the NPT is a better fit due to availability of fittings.
Well, yeah, it sure LOOKS like you've created NPT threads, but if you do a Section Analysis of the hole you'll find that there are actually no threads at all, just a smooth-edged hole. What's it's actually done is put an "image" of threads in the hole, and that's all. Try 3D printing it and all you get is a hole, no threads. There does not appear to be any way to easily produce NPT-style threads using Fusion 360.
That is correct. The actual “modeling” of tapered threads is still on their to-do list, but we have no idea when. I’d guess if you want to actually model them now, you’d need to look up the specs, create the proper tapered hole, then use the coil command to setup a path. Then make a sketch of the profile and sweep that along the coil to create the thread.
@@Schoelme the workaround I’ve seen people mention using on the Autodesk forums is finding a part on the McMaster Carr website (making sure it has modeled threads of course, most do, but not all) and then getting creative with chopping out and using what you need to combine with your own part.
great tip on the hole making option for ploppin in an npt!

Great video! Keep them coming!
Just what I needed. Thanks
THANKS FOR SHARINeitG THIS , i was looking for it , get confuse about somting with npt , about geometri , u select just hole when u thread mill
Well explained

@@BlackSmokeDMax same problem over here i need a one inch NPT thread for 3D printing and probably have to model it by hand :(
