Ken,
Normally I use a MTJNRS tool, using TNMG-322 and 321 inserts, with very good results. My question is, I was given a supply of VNMG-332 and 331 inserts, then went out and bought a MVJNR tool, I have not been able to get any kind of acceptable finish. As the insert is very sharp ended, I tried using it in tight positions and cleaning up grooved area, regards of speeds and feeds, it leaves a very rough finish, like it tearing the metal, not cutting. I've tried it on steel, aluminum and a little stainless steel, no matter what, its substandard. The inserts are from Mitsubishi and Sandvik and Ceratip, the results are pretty much he same regardless of insert used. Any suggestions or was buying the tool a waste of money?
