I have found that if you define the turret as "lower" you have to double check your tool orientations (upper left hand corner of the tool set up dialog box)

DavidB.. I have seen that "bang" as well... the little b***** dowel hurt when it hit me in the back of the head. 1. If i have a broken tap (non carbide, cuz i have never used a carbide tap), EZ Out is great in most cases, but an old worn carbide end mill is the best... 2. after my little crack in the head (yeah it happened, but maybe he just hit it through the clearance hole ) for dowels i drill a hole, force some putty down there and use a drill or drive punch to get it out. theres my 3 cents (inflation) FF

I happen to be having this same problem. it seems like i have to keep defining the material.

Hello, this is my first post so bear with me: Chipmakr said: We have tried without great success to use Greenleaf ceramic inserted tools in our hardmilling, but I can not get good tool life. I would really love to able to unlock the potential these tools seem to have. I have tried ceramic inserts with little success as well. From what I have been told after asking around, it has a lot to do with ridgedness of the machine/cutter. It seemed whenever we tried to use them, they shattered before I got any real wear out of them. This was in hardened (62Rc) tool steel as well. On the other hand, I have seen what these inserts are supposedly capable of. But in every demonstration I have seen, the depth of cuts have been relatively shallow. FF
