I’m pleasantly surprised that threadmills work this will in a Nomad.
We don’t call this is a drill and tap - this is a drill and threadmill. They are distinct operations, each with advantages and disadvantages.
Tapping is MUCH FASTER than threadmilling… but one needs a unique tap for each direction, size, and thread count. Lots of holes - tapping is faster than threadmilling. Tapping can go into really deep holes but blind taps - not all the way through a hole - aren’t so nice. They cut through tough materials like butter.
Tapping requires very slow speeds - lower than what the Nomad can do.
Threadmilling is nice in that one needs a small number of tools - one? - to cover a wide range of hole sizes and directions. They are designed for use in high speed mills - 30K, 40K, 60K RPM - which is why I’m surprised this comes off well in a Nomad (and why I didn’t even mention them above).

That was more for search-ability than correct nomenclature. Most people have heard of a tap and know what it does… I figured people new to cnc may not have heard of thread milling. (even Google thinks I always want to buy a new 3mm Treadmill… not!)
I have a different profile tool from Maritool that I’m going to try some M6 holes tonight. I’m a bit skeptical with regard to the rigidity of the Nomad, hence the reason why I took it really slow with the M3, but we’ll see.
cheers !

True, that is why I changed the name of the entire posting.
I’m very pleasantly surprised that threadmills work.
For those truly adventurous, they make threadmills that combine a threadmill (top) and end mill (bottom)! One can do the drilling, change spindle speed and program in the middle of the hole making, and threadmill! I’ve never had the courage to use such things and I don’t think the Nomad has a “Z” to make such devices very useful - the tools tend to be a bit long.
If you continue to have success, I will have to get some 0.125" shank threadmills and give it a try. BobCAD-CAM has all of the necessary support to do this kind of thing.

You can even make external threads with a threadmill!

Yup… not that any of use will make screws or bolts or thread pipes…

I’m hoping to use threading aaaaaalot. Haha. I’m glad this is all getting worked out now. Great job guys!
