Trying to cut 1/4 thick cement board. 1 1/2" thick strips.

I tried with my jig saw but the trailing piece snaps off. And my blades are getting destroyed.

I tried scoring it and lining up a 2x4 on it, kneeling on the 2x4 and lifting the opposite end. No luck.


Any other ideas?

Thanks

Diamond blade in a 4 1/2" grinder also works. Drill a 1/8" hole in the cap of a water bottle and you can cut with one hand and squirt with the other.

I wear an OSHA approved respirator and cut the stuff with a segmented, diamond blade in a 4" tile saw. See it here: harborfreight.com/4-in-handheld-dry-cut-tile-saw-62296.html

There is a water fork attachment available for the saw but I don't use it because I don't want to wait for the board to dry.

Cut some strips with an old blade and a table saw. Smelled like a fire in there. I was wearing a 3m respirator with the pink filters.

I was reading about silica dust (produced when cutting cement board) last night. Stuff is dangerous. Definitely wear masks when cutting this stuff.
