First, I like how it works. This is a chip breaking on metals that CNMG and WNMG had problems with. It was just long curls, and those are real chips. 4 came, the drill rod surprised me with a negative rake. The rest have a neutral edge. 2 out of 4 had the carbide not seated evenly. I contacted the seller and he said he would send me 2 new ones if I provided the address. But I decided to try to fix the holders. The screw did not match the carbide. I put the bag back and now it sits flat. Problem solved. The seller, I think, approached the replacement well. But now everything is fine. about 20-40 minutes work.
