Blade high makes the angle that the blade hits the thin sheeting closer to square. It is less likely to lift and tends to cut more smoothly.What's the reason for that?

+1. :yes: Just to add, that the more vertical angle provides less of a cutting thickness, which means less friction from blade contact, which means less heat, and less of a melting problem. I try to do all cutting with the brown masking paper on or the polyfilm protector that some sheets come with.Blade high makes the angle that the blade hits the thin sheeting closer to square.

If I'm cutting thicker stock, like 1¼" polycarbonate to be used for bank drive thru's or teller windows, I might use a 32T.I just finished 4 30x36 frames this week and they have .1" plexi installed. I cut the sheeting with my regular 40T Onsrud TC.
