Used on an Enco 4' x 1.5" bore lathe with a PhaseII 250-300 tool post. Works great for light machining, even on free machining stainless if you take it easy and lubricate. Comes with some replacement parts, but you will want to pick up a few more inserts because these wear pretty quickly. I would give 5 stars but something has to really be special for that, and these are just plain old index tools that do what they are supposed to.
