Ken - at some point I'd really like you to post some of the info that you posted on the forum that cannot be named, as that was such a wealth of information.
Prior to reading that, I had resigned myself to the fact that I could only use HSS tooling (even carbon steel tooling, given the vintage of my lathe). Whilst I do use HSS, I really appreciate the fact that I can get good results with insert tooling and spend the time I use to spend at the grinder actually making something.
For example, the VG112 R 16-30 parting/grooving tool has seen some heavy use recently and despite my top speed being less than 500RPM, it has worked beautifully.
The one thing I find problematic at times is the grade and chipbreaker. I've read the manufacturer's data and got the depth of cut dialed in so that it is at least breaking chips but some of the inserts that are for steels perform worse in 1018 (or similar) than some that are designed for SS or even cast iron. However, the flexibility of a quick insert change has made this less onerous.
However, it does beg the question as to how much do you believe the manufacturer versus testing and seeing what happens?
