I'm trying to drill a 7/8" hole into a piece of plexiglass. The plexiglass is an average width (came from ********** with the blue film on it but I'm not sure what the width is). Because of the size I bought a hole saw attachment in 7/8" and drilling slow but it's not working. Anyone have a better suggestion? Also, can I use a jigsaw to cut straight line in the plexiglass or do I need to bring out the wet saw?

Thanks!!!

Hello CyberHandyChick,

In my experience plexiglass "works" kind of like metal. So, NO, don't use a wet saw!

The hole saw may not work too well because those are typically engineered more for wood than metal (or plastics). I'd try to find one for metal. Or pick up a 7/8" drill bit instead of a hole saw. You can find these to fit in 1/2" chuck drills.

Jigsaw-wise, small teeth work better than the bigger woodworking teeth. And yes, slow speeds are better.

I've never made a large cut in plexiglass--like cut a sheet in half. I've heard you can use a carbide blade installed BACKWARDS--for instance in a table saw--BUT, no I have never tried this and I would suggest that we hear from some others or that you do some other research before you do. If you don't have too much to do, I'd just use a jigsaw--especially if you don't care too much about precision.

Regards,

I cut plexiglass on my tablesaw and mitre saw the same way I cut wood and have never had any trouble. no need to turn the blade around. I have only used a carbide tipped blade when cutting it though.

Thank you both for your responses. This will help a lot since I was scoring the plexiglass with a utility blade and then breaking it. This will be a lot less painful!!
