Cutting firebrick

[TimberGhost]

What is the best way to cut firebrick? I don't have a wet saw. Thanks!

Firebrick comes in a lot of "flavors". Some are a good deal harder than others, so it kind of depends on just which kind you have to cut. For general purpose replacement firebrick of the 9"x4½"x1¼" variety like Rutland sells, I use a masonry blade on a compound miter saw, and cut them outside with a dust mask on. Easy peasy. Rick

I score it with one of those wide chisels you use for breaking regular brick. Don't know what they are called, I just call mine a brick chisel. I score the brick on all four sides, smack it with a hammer and it breaks right away. I did my Rumsford fireplace that way, and it involved some more complex angles, and it did fine.

Don't know how anyone else does it.

I used a wet tile saw ($50 harborfreight), the rutland bricks are really soft... probably could use a hacksaw if you wanted to and took it slow. Would destroy the blade, but thats cheap.

I got the same 6 pack of bricks shown above.... only used one... 5 left in my garage just waiting

4 inch grinder with a dry-cut diamond blade.....and a good dust mask or respirator....just cut a pile of them the other night......don't forget safety glasses, too!

Last time I needed to cut a fire brick I used a normal every day hacksaw. Worked great.

Last time I needed some pavers cut I went to Lowes and they cut them for me for free. Granted I do A TON of buisness with them.

I've used one of these in the Circ saw. They are cheap and work fine for what I've done.

I've used a hammer and chisel, but you need to be careful and work slow. Just tap the hammer and keep moving the chisel along.

I tried that and after I broke $20 of pavers I gave up!
