Hey guys, been watching and reading this forum for a good while now and have learned some things from here. This is my first post so lets see how this goes.

We are machining Inc.718 on a Swiss. Running some test on the tool life.
Getting around 1000-1500 pcs per cutoff insert, but every every once and a while the insert will fail (explode) well before 1000pcs. Is this jusy the nature of the beast (Inc 718) or is there something I should be looking for?
