Run the cutter through your cut line multiple times. Press hard and roll over the edge a few times. Thicker glass is cut by a bigger cutter/machine.Im about to do a Redsea xxl 750 with chipped glass from moving it. I bought the same pliers as you but got a bit better cutter. Any tips?
Note:Running a small hand wheel cutter multiple times through a cut line will dull the wheel. it’s not recommended to use those beyond 1/4 inch glass.
