. Talk to these folks, they may be able to point you somewhere useful. Might also play with the angle your tool touches the material. Might also want to try a different grade of carbide.?

Not a lot of machining experience here, but did play with carbide tooling on the machines at school & at home. The working lathe at home is an Atlas. Not a terrible machine, but not as sturdy as a Heavy 10, either. Hope someday to have a functional Heavy 10L here. Still needs a bunch of work.?

Expect in one hand, expectorate in the other. See which one gets full first.

Hello all. I am looking for a source for HSS inserts to fit a particular lathe tool I bought not long ago from Shars. The tool (MWLN Tri-lock tool) came with a carbide insert (WNMG 332) but no matter what I do I can't get a decent cut with it. Am hoping that switching to a HSS insert will improve the situation considering the fact that carbide is really intended for speeds a little higher than my South Bend 10 heavy is made for. Shars told me that they do not carry any HSS inserts that will fit that tool. And I have been looking at other sources to no avail. Although I don't really know a good way to search. You can't search for "WNMG 332" cause you then come up with the above listed carbide insert. Thought I'd bounce it off of you nice folks and maybe somebody has a source I don't know about.
