Just ran my 10,000th part on the same insert and it's still cutting fine
I was doing a routine tool change on the old HAAS and the counter on the control said 10,002. I had to double check the log book, because I put that specific coated carbide insert in for a long run of aluminum brackets back in January. The finish is still holding within spec, which I honestly didn't think was possible. Usually I'd swap inserts around 3,000 parts for this job to stay safe. Has anyone else pushed a tool way past its expected life and been shocked when it didn't fail?

Yeah that's wild, I had a similar thing happen with a boring bar on some stainless. We were just waiting for it to go, kept checking the finish and it held for like triple the run time. Makes you wonder if the tooling specs are super conservative or if we just got lucky with perfect conditions.

Read an article a while back about how shops sometimes get a "golden batch" of inserts. The coating process isn't perfect, so maybe one in a thousand gets an extra thick layer or bonds just right. You might have gotten one of those. Saw a guy online who ran a single turning insert for a whole year on brass, just to see how far it would go.
