Unpopular opinion: watching a single point tool peel off a 0.010 chip still beats watching any screen
Found out from an old machinist handbook reprint that tool life can drop by half if surface speed creeps up just 15 percent, which explains why my inserts kept dying on 4140 back in 2019. Anyone else got a number like that they wish they knew on day one?

Ever notice how that chip color shifts right before the insert goes?
