I've been using my Tormach Superfly cutter to bring to dimension some 1018 steel blocks. The blocks are 1.250" square X 4" long. I'm removing 0.025" from each side to bring it down to 1.200". Each pass is about 0.005" DOC.
Well, the first side with a new carbide insert is like a mirror. Beautiful! By the time I get to the last side, the cutter has obviously dulled and the finish is dull and matted. I would assume the carbide cutters would last a lot longer than this. The inserts are Korloy SEHT1204AFSN-X45.
Does this seem correct? Should they last longer? Are there better inserts?
