Heard a guy at the shop say 'just run it' on a part with a 0.001" burr
He was setting up a job for 316 stainless and argued the deburr step wasn't worth the time. That part is for a medical device assembly in Rochester, and I've seen what a tiny burr can do to an o-ring seal over 500 cycles. Am I wrong for stopping the run to fix it first?

Holy cow, a medical device? In Rochester? That's the last place you cut corners. A burr that small will act like a little knife, shredding that o-ring seal over time. You were totally right to stop it. That's how you get a callback, or worse, a failed implant.

My buddy worked QC for a catheter plant upstate. They let a tiny scratch, way smaller than your burr, slide on a guide tube. It passed the first leak test, but after a few hundred flex cycles it wore through the inner liner. Whole batch got scrapped and it set back their FDA audit by months. That "just run it" mindset cost way more than a deburr ever would.
