How do I cut circles/curves in Lexan?


I have a sheet of Lexan that I need to cut a 4" circle in. The only tools I have are a Dremel and a hand drill (yay for apartment living ). Any ideas?

Holesaw drill bit. They make them up to 8" if I'm not mistaken. The bit should look like a big bowl and have a serated edge.

Ok, that's what I was thinking of, but I don't ever recall seeing one that big. I'll look again!

A hole saw is one of the best ways but the Dremel with the spiral saw bit and hole attachment would do too.

I looked on the Dremel site and it looks like to even use the cirlce cutter, I'd need the High Speed rotary saw instead of the regular Multi-Tool that I have now. While I'd love to own more tools, now is not the time for me to be upgrading my collection

what would happen if you cut a jig in the pattern you wanted from plywood, then clamped it to the lexan and attached a dremel cutting bit to your drill. thats what i did to drill my fan holes for my case, worked like a charm and saved me 12 bucks (cost of a hole saw)

Be careful when cutting with a hole saw though. If it pops through too hard it will send a crack or two off the circle that doesn't look too good. Make sure to have some support behind it, that helps defeat this.

Lexan won't crack, but you do need to make sure you clamp it b/c the darn thing is going to want to take off on you.

Does it NEED to be polycarbonate? Because you can order discs or acrylic cheaply from McMaster or USPlastics

router with a straight bit is the best way to cut lexan. Just set up guides for the router to follow.
