Cuts a perfect 1.313 inch diameter circle for use with our 1 inch ProMaker Button Machines, 1 inch MultiMaker die sets, and 1 inch Button Parts. Our 1" graphic punches are just like a big hole punch. You print a sheet of circles (i.e. your button designs), cut them into strips, then feed the strips through the 1 inch 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).
