This heavy duty, professional grade circle cutter cuts a perfect 1.837 inch diameter circle for use with our 1-1/2 inch Button Machines, the MultiMaker 4000 outfitted with the 1-1/2 inch die set, and 1-1/2 inch Button Parts. This graphic punch work just like a big 1.5 inch hole punch. You print a sheet of circles (i.e. your button designs), cut them into strips, then feed the strips through the 1.5" circle punch one at a time. The opening in the top allows you to line the circle up perfectly. Once your image is lined up, you push the lever down to cut the paper, then push the center of the hole up from the bottom (theres a little piston that slides up) and it ejects the circles out the top. With some practice, you can cut up to 5 strips at a time using 5 mil. paper (However, this is not guaranteed. Only 1 layer at a time is advised by the manufacturer for accurate cut).
