circular magnetic cutter?

Anyone have any source for a magnet cutter? We produce a lot of circular magnets by printing to a vinyl decal, applying the decal to a roll of magnetic material, then cut by hand with an xacto. I have yet to find any kind of punch or cutter that doesn't leave a dimple or pin hole right in the center.  

  • Hello Myron; I would think a gasket cutter would do that, but if you have a hard time finding the right size you could get a piece of steel pipe and sharpen the edge the same a hole cuter.

    • Thanks George. Yeah, we had a machine shop make us a type of die cutter and retrofitted it to an old T-shirt press we had laying around. We made a template that uses 3 steel dowel pins placed around the die. The idea was to print the three holes outside the area to be cut. Then with a hammer and punch, knock out those three holes then set the magnet over the steel pins and pull the press down. We can cut up to 3 at a time but it's really time consuming to punch the three holes in each and the cut still isn't as clean as an xacto by hand. We have to sand the edges afterward too. Gotta be a circle cutter out there.  

      • You can get a blade holder and center pin holder that mounts to a rule that would cut magnetic stock, and I guess set one made for a drill press. And I guess you know you have to cut past the vinyl covering and the rest will brake out when pushed out. and you could look at the cutters for channel letters also. We do cut magnetic sheeting to the shape of a design screen shot below. The little guy in the picture was 5 years old and he's 31 now.

          I've not used that particular one, but I seem to remember using something similar about 30 years ago.
      • Hi Myron

        Sorry I don't have a picture of our old one. we had cutting dies made at a tool and die shop and placed them on the bottom of the heat transfer press we use for dye sub and transfer shirts. we would put the magnet material on top of the dye then a piece of styrofom on top then press . we did 50 pieces at a time for years it was very fast for us.
