Bad case of "OverBite". I've seen idiots in the trade with a 4" KO set drill across a panel with one side single layer and the other the cutter on two layers. Bent arbor then a blown split die due to "OverBite". Idiots first class when a sheet of scrap to match the double thickness would of allowed a straight punch thru. Check the price of a GreenLee hydraulic set these days of 1/2" to 4". My set stays in the shop at home with one user, me, achet set included. The bad thing the KO set size does not match the coupling unless you lathe a step in the half couplings or make your own. Good N tight Fit is best Ya Ya!.
