Have you tried the CCGT inserts? Yes, I know they are for non-ferrous but I've used them, at the appropriate speed, for 304 and 316 austenitic stainless where they work well for finishing cuts and boring and low power lathes should benefit from the reduced forces because of the top rake, they perform much like HSS.I maybe doing something right or wrong but I got the hss lathe tool from it to cut vastly better than the CCMT 6020 carbide insert.
Thank you- I got my 8mm set of tools from Chronos. I'm very happy though with high quality hss tools-- driven by a Quorn etcIf your asking about the inserts, they'll definitely be available pretty much anywhere. Just a quick Google search shows Chronos has a package of 10 inserts for £20
Hi Jon,After having a quick think, it may be possible to bore the spindle, IF the bed is flat, by turning the milling head 180° and hanging it off the back of the ML4 bed, by bolting an angle plate to the tailstock end of the bed, would be a bit of a precarious setup though on a cantilever bed.
I'll look up the articles if I can.
