1) You can use a 5 pitch insert, but you may need to grind a little relief in it to get the depth. But it will have less tool pressure as the end is only .0689" wide or 20% or so less. . Ideally, the cut should be on one surface only, so it might be possible to cut an acme thread by using a 29.5 degree cutting tool to the desired depth, and then advancing the . You would need a very skinny tool shank (almost certainly a custom tool), and be very limited in depth if you tried to threadmill this. I would buy some threaded rod from the .
Acme threading will work best with a 2:1 length to diameter ratio. This means the most unsupported stick out you should have is 0.322”. You may have to center drill the part .

Micro 100's ACME solid carbide thread tools are optimized for cutting pitch-specific ACME threads, and feature a polished split face for improved edge retention and chip evacuation . Laydown threading tools would be the best, with angle shims to get the clearance that you need on the insert. Such animals are available. I would recommend that you have a . i have to cut a 4.750 stub acme internal thread. its 1 tpi and 6 leads so each thread is 6 inches in one revolution. im testing this out in a big haas tl lathe and it accepts fanuc style .
1) You can use a 5 pitch insert, but you may need to grind a little relief in it to get the depth. But it will have less tool pressure as the end is only .0689" wide or 20% or so less. 2) You can use a narrow grooving tool and pick out the thread bit by bit, then surface the thread using the radiused corners of the inserts. I was thinking about using a cutoff tool to cut the external block threads with, and then a grooving tool to do the internal threads, but it's hard to find a cutoff tool that narrow that would also work for me as a regular parting off tool.
For cutting steep threads (acme or other) I've made a simple tool that holds carbide bits that can be adjusted to any helix angle. In fact I use this tool for most of my threading on the lathe. The one shown here is 5/8 dimeter using 1/8 inserts (ground from . Ideally, the cut should be on one surface only, so it might be possible to cut an acme thread by using a 29.5 degree cutting tool to the desired depth, and then advancing the cut along the axis until the proper form is created. You would need a very skinny tool shank (almost certainly a custom tool), and be very limited in depth if you tried to threadmill this. I would buy some threaded rod from the source below and then file/grind some cutting edges into it to make a tap. To get a real handle on the specs of the Internal Thread: 1. Ensure there are no burs and hangups on the Internal Thread. 2. Plug the through hole up to the bottom of the Thread with Plasticine. 3. apply a good release agent to the Internal Thread and cast a mating Male Thread using Epoxy Resin, say Devcon. 4.
Acme threading will work best with a 2:1 length to diameter ratio. This means the most unsupported stick out you should have is 0.322”. You may have to center drill the part and use a live center, or chuck closer to the threading area to reduce part deflection. You would need a very skinny tool shank (almost certainly a custom tool), and be very limited in depth if you tried to threadmill this. I would buy some threaded rod from the source below and then file/grind some cutting edges into it to make a tap. Cutting Acme threads on a CNC lathe requires the right tooling, proper setup, and careful monitoring of cutting parameters. By following the steps outlined in this article, you can easily cut Acme threads on a CNC lathe and achieve accurate and high-quality results.
