Some time ago someone posted to this group that they buy used carbide and I think many, myself included were wondering how trustworthy he is. He didn't directly answer any questions but occasionally would post something saying we could trust him if anyone seemed to challenge him. I seem to recall at least one person using his service and posting that they were satisfied.
At any rate, I just found out that Kennametal is buying too. Their current price is $7.75/lb for inserts but I don't know whether they have a minimum. You can also get a Kennametal credit or invoice reduction if you prefer that over cash but I don't expect to be able to buy anything from them any time soon.
