Cleanly milled. Another comment about them being cut is just plain stupid! They should be milled with right cutting angles so that they splinter properly. I have a lot of high quality knives. Honestly, there's nothing better than those high $$. One of my bets was a blank page out of the box on one side. By price. happy to buy just one insert holder for the price. You will receive 3 ready-made cutters with keys. I took part so you can see its parts. I have no complaints about these incisors. I had no trouble trying on properly sized branded inserts in holders. Each came with the correct cutting angles!
