Trying to work out if I'm going to set up my new Bolton CQ9332 with carbide inserts or grindable HSS. I've been told here at CNCzone that carbide inserts are for lathes that are more rigid than my imported 9x22 1hp MT5 lathe. Yet, I've seen videos of my exact lathe being used with carbide inserts installed in the stock 4-way toolpost.

Also, are there QC toolholders (like for the Phase II rigs) made to hold HSS? I think the size I'd need is 1/4 square, right?

Thanks.

(Note, obviously I'm new here and I accidently posted this same question in the general metalworking machines forum .. my bad).
