Had a brand new endmill shatter on me mid-cut last Tuesday

Was running a tight tolerance pocket in 6061 aluminum and the thing just exploded around 9:30 AM, sent chips flying everywhere. Turns out my collet nut was slightly loose from a tool change earlier - anyone else double check their holders after every swap?

Used to think it didn't matter that much until I had a holder let go on a finish pass. Definitely changed how I check things now.

My old boss had a collet launch across the shop at 7 AM one Tuesday.
