Might have been me, but there are several others that recommend them too. They last pretty well if you don't get to greedy with the DOC and feed.Funny, I was just typing that I'm going to try 32.50 CCGT/CCGX inserts and reducing the stick out next. I don't remember who recommended them to me first (may have been you actually) but they're handy to have. I was actually turning some 7075 aluminum to make an outboard spindle spider for my Sheldon over the weekend and was shocked at the finish I was getting.
I was playing around yesterday rough turning a piece of alu (6061 most likely) at 35 thou DOC, 500 rpm @3" diameter and feed as hard as I could without causing the belts to slip =
I needed to wear a hat, those were going everywhere, even with the chip guard (off, on right)!
It would cut at 50thou but I couldn't feed fast enough to break a chip without stalling the lathe, so got nasty ribbons instead. Shallower cuts with the same feed produces the long spirals you can see at the back
