How to salvage core portion out of a bar stock for expensive material? 10

Experts: we buy large diameter nickel based alloys and we really prefer material in tube format, but you know often times we end up with getting bar stocks. What is the best way to get the core portion out and save it for small parts?

my boss actually does not care about this yet as I said our current qty is just 1 or 2 since we are in prototype. I like arunmrao just think it is a huge waste. I would propose to my boss for production later on. Again all the discussion are valuable I very much appreciate them.
