Cutting Arborite sheets cleanly and quickly.

I use a Richard's scoring knife that has a carbide tipped point

Yes, that's the name I couldn't think of. That's the one I use too.

Thank you !!

I have and used a scoring tool to cut/break Lexan and some plexiglass, after I tried to saw it, (was melting and sticking to the saw) the scoring tool worked perfectly.

Much like this one from HD

I have Carbide tipped pull knife made by Reynolds as I recall. Several passes on the Arborite and if it's not cut thru' it snaps off clean anyway. If you need a super clean edge, cut it slightly big and trim the edge with a router.

EDIT : as per Andre (2 posts down) it's a Richards knife, NOT Reynolds.

table saw or 1/4" router bit

I've also used a carbide scoring tool to score and snap off. I find cutting a straight line with a small Rotary blade difficult compared to scoring along a metal straight edge.

I've cut it by scoring it very deep with a knife and then snap it off.

I recently decided to cut a piece from an old 1/16th inch thick Arborite sheet I had hanging around in the basement to cover a 14 x 12 inch access hole that the plumber cut into the wall last week when he replaced the entire bathtub faucet-valve-spout assembly. I had forgotten how to cut this material which is very brittle and chips easily. I tried a mitre handsaw which worked but was too slow and a strain on my recent rotator cuff injury in my right shoulder. I tried my jigsaw in a table I made for it and it chipped the Arborite twice while cutting. (I know I could have tried using the jigsaw by hand with tape over the cutting line but I didn't.) Then I tried my Dremel rotary tool using the right angle attachment with three different cutting disk types. In the end, this little carbide cutting wheel worked the best. It cut quickly, cleanly and stayed on track. I was pleased and relieved to have found the best way to cut thin Arborite so I thought I'd pass it along. (On the safety side, I wore my safety glasses which protected my eyes from specks of Arborite kicked onto my face during the cutting.)
