I got these with my lathe. Anyone ever use them? Any good? I’m planning on going with a QC post. Was thinking of having an adapter/insert made the cutter could slide into then get mounted in post? Thoughts? Pictures to follow.

but I think it's important for new guys to learn to grind their own cutting tools. It saves money, but more importantly, you learn a lot about cutter geometry and how it relates to your job
Depeds on the quaity and grade of the carbide, best sharpened with a diamond wheel running with coolant. ...
Or, in other words, it is AT LEAST as important to have SOME understanding OF WHY a tool cuts - as it is to know something about making a lathe go.
To optimize results needs optimization of BOTH sets of understanding. Very little of this takes place over the counter at the machine shop supply - or its modern "on line" counterpart
These folks knew something about what they were doing 105 years ago when carbide was some outlandish future improvement undreamed of yet

I'm not sure why I keep them.
Bill, after a while, all it is is touch up grinds, unless there is some weird profile you need to cut.
