The Dremel on low speed should easily cut through acrylic. The best way is to score it a few time and snap it.

If you have a jigsaw I am surprised at the question. A jigsaw is an excellent tool for cutting acrylic. Just tape the base up to prevent scratches and use the proper blade. Not a metal cutting blade...but a medium tooth wood cutting blade.

only reason i asked was because my friend was saying that the jig saw was the worse way to cut. the cutting and snapping never works for me on 5mm acrylic.

I do it on a small bandsaw with a metal cutting blade, of course you can't do holes with it.

I use a dremel with a rotosaw bit. Works fairly well and fast! much quicker than using a reinforced cutting disk.

1. Bandsaw
2. Jigsaw with medium blade
3. Dremil with side cutting bit

that is the only good ways of cutting it and looking somewhat professional

I fab acrylic all the time in the marine industry..
The best way is with a router bit with high rpms a two flute straight bit at least 3/8 in diameter works alright but a spiral 1/4 bit leaves a superior finish especially if you plan on polishing the edge cut. I usually use ball bearing guided bits and a straight edge clamped to the acrylic piece. It also enables you to produce exact duplicates if needed.

Hope this helps

Sorry, I forgot to mention that you need to control the speed of the cut, VERY important with brand new high quality bits that seem to have a mind of their own. execessive speed not high rpms will cause micro chipping you will see tiny little chunks taken out of the acrylic. Test your speed with a practice cut. Don't let this throw you off it is very easy to do and gives you a superior finish than all the methods used above. If you dont have a router or similar tool, Bosch makes a jigsaw blade specifically for acrylic or the
T101B blade by the same seems to work just as well

I cut acrylic with a laser at work using a vector based template in CorelDraw. Works amazing.
