sawing in firebrick

[Jazze84]

Hello

I have some tiles that are 230x114x25 mm and need to be cut, we're talking about 2-3 pieces.
I have a jigsaw and wonder if there's a specific blade that can be used to cut brick with, or are there other easy, inexpensive options to cut/saw with?
I would prefer not to buy an angle grinder with a diamond blade or similar.

Bricks too hard, especially refractory bricks that are fired hard, no regular saw blades can cut them. Blades for ceramics and bricks are short and may not go through the stone, it might be possible to saw from both sides. Here's a type available in several stores.

Brick for hard especially refractory which is fired hard, no ordinary saw blades will take it. Blades for ceramics and bricks but are short and probably won't go through the stone, might be possible to saw from two directions. Here is a type and available at several stores.

Thanks a lot, the cut doesn't need to be pretty or straight, it won't be visible. I'm going to stop by K-rauta and buy such a blade
can you also use these?

Yes, it will probably work, a good blade of Bosch quality, no junk

Yes, it will probably work, a good blade of Bosch quality, not rubbish

Super thanks!

Remember to soak before sawing, so you avoid much of the dust... It's not healthy...

Thanks for the tip!

If you soak it, the dust can clump together, but try a little light scrubbing without wetness, preferably standing in the wind, with your back to the wind, so the dust blows away from you.

Edit: Beware, dust from bricks is a pain to remove and stains everything, so make sure the dust blows in the right direction.

If you soak it, the dust can clump together, but try a little gently without wetting, preferably stand with the wind at your back, outdoors so the dust flies away from you.

Edit. Note that dust from brick is a H-E to remove and stains everything, so make sure the dust blows in the right direction

ah, maybe not a good idea to do it when the wind blows towards the neighbor, so to speak =D

 

[Dan_Johansson]

ah, maybe not operate when the wind is towards the neighbor so to speak =D

Now the jigsaw blade is probably better than the angle grinder in terms of dust, but when I built the wood-burning oven, I had the stones lying in a bucket of water, it wouldn't work otherwise (with the angle grinder then)...

If it still won't be visible, wouldn't it be easier to hammer along the desired break with a hammer and chisel?

 

[Jazze84]

If it won't be visible anyway, isn't it easier to hammer along the desired break with a hammer and chisel?

Yes, that will definitely work, they won't be visible or need to be very precise or neat. Is it just placing the chisel on the desired direction and hammering it in?

 

[Marcussjogren]

Yes, absolutely, it won't show or need to be very precise or neat. Is it just laying the chisel on the desired direction and hammering away?

The best would be if you have a chisel designed for brick/stone, but I bet a regular screwdriver would work too. It might get damaged though.

I would have drawn a break line, tapped gently along the line a few times, and then gradually increased the force. This is to get as neat a break as possible.

The meticulous type would probably tap gently on one side and then also on the other side. It might be slightly more accurate then

Yes, that sounds like an option too, I'm going to Hornbach tomorrow to see what chisels they have in stock.
