Re: Cutting refractory bricks

I once made a machine for cutting bricks in half out of an old hydraulic press. I made a wedge shaped metal plate that attached to the piston so when it pressed down on the brick it split it cleanly in two..

I started with one of these..

Re: Cutting refractory bricks

Makes sense! I have to point out to all observers that I have no building experience whatsoever!! Therefore to an enthusiastic amateur this forum is an amazing asset.
Thanks to all.

You can get block splitters in the UK like that:

Years after the fact, I learned the secret for cutting on a seven inch flat table diamond saw: sit at the back and pull the brick toward you. This keeps most of the mud out of the face.

Thats a neat thing. on the same page, they also have nine and twelve inch masonry blades for 30 and 40 pounds per. Norton makes good abrasives, but three hundred bucks seems out of line to me.

I like the block splitter.. Mine worked the same way but with a piston.

Just thought i'd mention Evolution tools.com have Diamond bladed compound mitre tile saw (Dry Cut & lots of dust !) 10" blade easly manages 3" blocks. It cost me ?200 from machine Mart ....done the job nicely! Check out my pictures to see the results.

Hi, Jeff, Welcome!

(Dry Cut & lots of dust !)

I know that it's been said before, but it can't be said often enough. When dry cutting, protect your lungs! Protect your eyes! Nothing in that cloud of dust is good for you.

Re: Cutting refractory bricks

Dmun, I completly agree eye protection and a dust mask are the minimum.

I have seen many pics where the happy builders
wears no protection at all ,the same goes for the
ceramic blanket even thought asbestos is out of
the picture these are REAL hazards, so,protect yourself!
.....And yeah don't forget to wet those bricks!
Here's a pic of yours truly just to drive the point clearly,
some of us need a pic to remind ourselves of safety being #1

Re: Cutting refractory bricks

I've been considering buying a cheap (EUR 125) wet saw, the type where the blade runs on a sliding rail above the brick to be cut - the only downside as far as I can see is the 30mm maximum cut @ 90 degrees. I've seen some 50mm thick bricks for sale, so thought I could modify the saw slightly by raising the rail and cut the bricks on one side before turning them over and cutting through... has anyone tried one of these saws? I recently cut a load of old 25mm thick terracotta bricks with a 9" angle grinder and ended up looking like a terracotta statue, not something I want to repeat!

Re: Cutting refractory bricks

It's perfectly legitimate to score and break, and since the cut edge goes out, mostly it's not seen anyway. The original plans were designed to have the bricks halved with a brick set,




but using a brick set to cut bricks has never been one of my skills.
