Hi all,
I'm doing a job that involves cutting fairly small details into/through cardboard. I'm using a normal 1/16th" carbide drill bit, and it absolutely chews up the top surface of the stock - lots of loose paper fibers and attached shapes. The bottom surface, which is spray-mounted to my spoilboard comes out clean, but I need clean holes on both faces.
What I'm wondering is if there's some known method of treating the carboard to stiffen it prior to cutting. Maybe even a simple enamel would do the trick, but I don't necessarily want to darken the cardboard too much, or leave a weird coating that could crack or crumble.
Or maybe there's some kind of specialty drill bit?
I'll be experimenting throughout the day, and I'll report back if I discover anything, but if someone could help me avoid reinventing the wheel, that'd be wonderful.
Thanks!
