Plexiglass
- Thread starter packratt
- Start date
A circular saw blade for metal roofing should work. It has rakers that prevent grabbing of the teeth and subsequent shattering of the Plexiglas. I have cut plexiglass on a table saw with a regular blade by feeding it very slowly.
By all means, pretty-much any motorized sawblade will do. The largest factor to pay attention to, is the feed-speed. Take it slow. Stay centered. The more you 'rub' the blade alongside the cut, they more heat is formed and the plastic starts to 'smear'/melt.
You want to avoid that. Otherwise, make sure you use your PPE and just take it easy.

With plexiglass, how to cut it may be a matter of the tools you have at hand.

The equipment recommended so far is on point but would add one crucial piece of advice not mentioned.
Plexiglass will scratch fairly easy so make sure whatever tools your using are clean and it wouldn't hurt to add some protection over the plastic masking just to ensure you don't scratch the surface while running a saw over it during the cutting process.

Use a lower tooth count blade with high radial and tangential tooth clearances if possible. Table saw with adequate support / help would be best. If it doesn't come with the protective peel coat, make sure you protect the surfaces from scratching. Fine grit sandpaper can clean the edges. Flame polish with a torch if you want it really smooth.
My family works in the business of cutting glass and plastics for window applications. As have I for a number of years growing up.
Take your drag knife and score your cut like you would normally do, then continue scoring deeper. Your can do this as many time as you feel you need to but half a dozen of heavy draws are all that's necessary. That works for big sheets. If your cutting just a little off, say under a couple inches then just continue scoring the cut deeper.
I'd highly advise not using a saw that has teeth as it will cause stress fractures.

Lots of advice given here. Most is worth exactly what you paid. You don't need anything special to cut plexiglass, or even thin aluminum for that matter. If you're using a "Skill" saw... just standard circular, if you turn a blade backwards , set the depth to just pass through, and have a firm grip, you"ll be fine.
