The other thing that is also often mentioned is the need for high speed. While this can be true for a lot of carbide tooling it is not needed for the sharp polished inserts. I use this type of insert most of the time on a lightweight machine and they cut well at a wide range of speeds.


Plus 1 to that too.

Absolutely, even at a creep the seem to work wonderfully.

Be good if someone tried all the combinations of inserts at hobby speeds and powers and wrote the results up for common metals.

I'm working on it, with the agreement of our esteemed editor. The introductory article is written; just need to do the trials for the first material. The only downer is that the experiments will be done on a Harrison M300, but that's what I've got. I'm not going to buy a fourth lathe just to do the experiments, and there would be nowhere to put it except the sitting room. And I've already got a lathe in the sitting room.
