Back in '08 at the old Johnson Machine shop in Dayton, we had a crash that taught me a lesson.
A guy on the night shift ran a 3-axis mill with a worn-out tool holder, and it let go halfway through a 500-piece aluminum run. The foreman made us all sit down the next morning and trace the whole failure chain, from the missing maintenance log to the bad setup sheet. How many of you still do a full tool holder check before every big job now?

Our foreman in Toledo made us do a five-point holder check after a similar mess. I still run through that whole list before any long run. It just gets baked into your routine after a scare like that.

Oh man, that story hits home. We had a nearly identical thing happen with a CAT40 holder on a big stainless job, just a total wreck. Our shop lead made us start doing a full visual and pull check on every single holder, no exceptions. It feels like a pain for about a week, and then you just can't imagine not doing it. That sound of a tool letting go still makes my stomach drop.

That "sound of a tool letting go" Laura486 mentioned is the worst alarm clock ever.
