I'm cutting 3 mm Dibond with an Amana 51508 3/16" cutter and it cuts great and I'm getting great results. However, I used the same cutter to make some 1/4" holes and things got weird. I have vinyl graphics over the Dibond and a layer of 3M matte overlay over that. When the holes are cut, a little circular piece of aluminum (the top layer of aluminum on the Dibond) comes off and is forced under the vinyl. It tears up the vinyl when doing this.
Does anyone have any suggestions for stopping this? I have no problems when routing but only when making the holes.
Thanks for any advice or ideas, TM.
