Cutting plexiglass

[noobpool]

Hi
I understand that plexiglass and plastic glass are the same. I have seen videos online where people advise to buy a special knife that makes a score in the plastic and then you can safely snap it off, where on earth do you find that? I know a hacksaw is also possible but I'm terrified of uneven lines as it's not my strong suit.

It is possible to cut with a handsaw (fairly straight) or I even managed with a miter saw.

angle grinder and thin cutting disc..

Should work with a regular utility knife, where you make a score on both sides and then snap along a straight table edge.

A completely ordinary fine-toothed handsaw is the simplest.

With an angle grinder, the plastic melts if you happen to pause in the cut. The material also becomes a bit brittle, in my experience with angle grinders and plexiglass.

Plexiglas cracks easily if you're not careful. Last time I sawed 1.5-meter lengths with a handsaw. It works fine, but if it catches, you'll soon have a crack. It's not exactly cheap, so you don't want to have to buy a new sheet. Different thicknesses are handled differently. Google it!

Plexiglass is a brand, acrylic plastic is the material. The best way to get straight edges is to score and then break:

Plexiglas is a trademark, acrylic plastic is the material. The best way if you want straight edges is to cut and then break: [media]

But what kind of blade is he using to cut / score?

Usually works better if you tape the glass...

It's probably just a regular utility knife or something similar. For cutting acrylic plastic, you don't need a special knife like for glass.

EDIT: I see that it's a different knife he's using, and it seems to be called a plastic cutter. I've done the same thing with a regular box cutter, so it's not necessary, but maybe it's easier if they've bothered to make a special kind for it.

Is it okay to drill larger holes? e.g., 30mm. What type of drill bit? Small holes are no problem.

Have cut with an angle grinder and metal disc. Smokes a bit but works if you don't need the highest finish.
