I've used the CMT 10 80-Tooth Continuous Circular Saw Blade P10080 with good results. I'm sure this one would work to DeWalt DW3218PT Precision Trim Saw Blade, 10" 80T Coated Blade. I think both are available at Lowes.

i used the 18 tooth blade that came with the black and decker 18 volt. worked fine for me, i used it to cut down a prefabed over flow.

Just a bit of note for those who work with acrylic; if it helps great. When I had my cabinet shop we did a lot of work with acrylics. After cutting we would use a rotary sander to smooth out the rough edges leaving a frosted look on the edge. To rectify this we would take a propane or benzene torch and 'glaze' the edges for a polished look. Practice with some scrap first. Good luck.

I have read (and been told) that if you flame polish and then try to glue/solvent weld the pieces, that crazing will occur where the acrylic was flame polished. The preferred method is to route or joint the edges when you are going to be gluing/solvent welding them.

Flame polishing will also reduce he strength of an existing weld. Never flame polish an edge that you will later weld.

I use a tenigru plasticut blade and it leaves my edge perfect with no other prep work needed, but I heard that any carbide blade works well. I would lube the blade with something. I use cut-ese but someone posted recently that bar soap works as well.
