So getting around to selecting some tooling for my Mazak 10N lathe.
I have many questions, this being my first turning center, so go gentle on me here
It looks like the large diameter 1"+ bars using *NMG inserts are pretty common, I read the thread about the pros and cons of V- W- and C-.

I have some parts I'd like to try as the first ones which will have a 1" bore, leading me to smaller bars with positive rake tooling.
This set looks like what I could use (forgive brand, just trying to illustrate) to create the size.
However on ebay I see solid carbide shank bars with CCMT 32- inserts in the M&M tools store.

Coolant thru vs. solid carbide more rigid..CCMT vs. TCMT how to decide? Any pointers? I'm sort of inclined to get both and do my own testing unless I'm way far gone on what I should be using.
Also, my machine has 1-1/2" bores in the boring bar holders, is this typically a shouldered sleeve/bushing with clearance holes for setscrew?
(in concept...with geometry to fit my machine)

Thanks for any help, I think I understand the basics of manual machines reasonably well, but the details of the Mazak are a little fuzzy right now not having seen one fully tooled in action.
