Thread: Metal Lathe tool holder advice

In regards to your CCMT inserts I dont have a great deal of knowledge as to there ability to be used as you described.

I was under the impression that they were a positive rake insert ( I thought this meant they could only be used on 1 side only.)

As I mentioned earlier you can Slide and Surface with the 1 tool and the 1 tip but if the cutting edge was dulled by Sliding you would probably have limited use Surfacing and vica versa.

Can you either explain or show a picture of your tool holder or set up that allows the CCMT tip to be turned over and used.

As it stands at present I have only been using 1 side,if in fact they can be turned over and used that would be a bonus.

Sure... Im not sure what inserts I was looking at the other day on the sandvik site but it claimed to have 16 cutting edges.

Im not sure if we're talking about the same thing. The set I have has a turning and a facing tool that each use one of the unused corners (SCBCR & SCKCR). Effectively that gives you 8 edges to use.
