Table Saw Blade Recommendation

[Ajaxus]

Alright, this is the best section for this. I recently purchased a sheet of Polycarbonate for a project I'm doing, not knowing that finding a table saw blade to trim it down would be a near to impossible task.

The sheet I'm working with is 1/4" thick. I've done some research on the table saw blad but finding what I need at a decent price seems to be a near to impossible task and I was hoping some of the machining experts over here might know of a decent blade that will get the job done without damaging this piece of Polycarbonate.

Thanks,
Aj

or a fine toothed carbide blade

I kept reading that I needed 3-5 teeth per inch which would mean basically a 120 tooth 10" blade, which isnt exactly easy to find. Then other sites were telling me 72-80 tooth blades would work.

So would I be allright with a carbide 80 tooth blade? Because I'm hearing that the more teeth the better.

I would give it a try on a test piece first, but I would give it a shot before buying an real expesive blade I may never use again.
I'm sure you could always sand the edges.

true, but i only have the one piece of polycarbonate so its a do or die situation since the stuff is fairly pricey.

Im thinking now that I'm gonna attempt this with a dremel tool, I'll post the results tomorrow.

Dremel sucks, the material clogs up behind the cut. Use a carbide blade and wear safety glasses. Little chips fly everywhere. Take it slow and let the blade do the work.

The dremel worked, just finished cutting. I used a carbide and diamond tips, diamond was faster and probably the way I should have gone. Only thing left to do is cut up my glovebox and I can have pictures on here of the finished product. :)
