I can't upload pictures from my iPhone so I'll have to do it at home. But basically I have I 3" 6 flute shell mill the I use only on aluminum and have been isn't it for years with only 5 inserts. The 6th insert spot has a piece chunk missing from the tool itself from before I started working here. The piece missing is directly behind the cutting edge of where the insert would be. It's not huge but there is enough material missing to make me question if it's safe to put the 6th insert in without blowing up the tool. Anyone have an opinion?:banana:
