Very tempting. I just today had a chance to demonstrate to my son why the carbide versions make it hard to take a fine cut and why I switch back to HSS in holders for such things.

Carbide doesn't seem to do well on light cuts...

Carbide insert tooling was developed for production use on high horsepower machines rigid enough to make passes to accurate finish size with heavy cuts, pretty much the exact opposite of most HSM use.

Except for sharp, positive-rake, submicrograin carbides, which ought to be very good for HSM use.

Who makes them? The holders I have came with TCMT-32.51, whatever the hell that means
Triangular, screw attached, 3/8 IC
What degree relief? Cutting at fairly low speeds, 150RPM to 750RPM
Materials range from HRS to aluminum. No bronze or stainless or phenolics, yet.

I don't know who makes them. Several brands appeared around 2000 and 2001, and then I got out of metalworking and didn't follow up. I had a couple of samples that I tried on my lathe (SB 10L), and they seemed to work fine. Those were Seco, sold by Carboloy at the time.
I'm hoping someone who has a need for such inserts will look into it and get back to us. If I get some time I'll try to do it myself. What you're looking for is positive-rake inserts made from submicrograin carbide.

Seco is know to be expensive. :-)
What I am using for fine cuts is: DCMT11T304 SS in CU7033 (uncoated). Not perfect because of the 0.4mm tip radius. A smaller would be better (but that also depends on your minimum feed rate). Suggested parameters: f (feed): 0.05..0.2 mm / rev ap (depth of cut): 0.15..0.8 mm BUT it cuts nice down to 0.015 mm. vc (cutting speed): 115 .. 175 m/min You always have to try it out and change parameters like feed, cutting speed and lubrication (this one works very good dry, but only with light (0.2mm ap) cuts).
Please don't tell me that you do have a different nomenclature for the inserts. :-)

But it cuts plastic. I used a triangle to cut some white pipe. The tip was so small - I lusted for a nice round nose HSS. So I put on my Armstrong holder I made for my Tool post and Turned the plastic nicely. Then used my carbide cutoff tool to square the ends.
