Mitre Saw?

[spinal]

Hello!

I have a new build in London, and am looking at the cheapest way to cut fire bricks...

I have a cheap (wickes) 190mm mitre saw - but can't find any masonry blades for it. Similarly, while I can find plenty of 230mm blades, I can't find any 230mm mitre saws!

Ideas?

Hello Spinal.......welcome to the forum.

A 9" (230mm) angle grinder with a diamond disc is best for cutting fire-bricks.Someone posted last week that the £13 diamond disc from "Srewfix" cut the fire-bricks well......as long as you soak the bricks first (ongoing debate)

If you click on the "search" facility at the top of the page and enter a few keywords, you will get a lists of threads where that topic is...or was being discussed on the forum.

It would be nice if you shared your build with us, but you will get a lot more feedback if you start a new thread here

welcome aborad,

the issue is that the bore on the blades is different for mitre saws and for angle grinders / table saws.

I brought a norton clipper pro blade, it was in their blue general building materials range and it did the job very well, I think they have now changed the blade and its the norton euro evo zml blade, you can get 180,, with the 30mm bore you require on a mitre saw. I have no idea where stocks it I only saw german sites and it was a little pricey.....

i have also found on ebay a diamond blade for asphalt by norton of the same size, I am not sure how well it will work, but its a fiver delivered so perhaps buy a couple. ?

its fair to say the chapest way is just a hammer and bolster tho, you can split them in half pretty accuratly, and its only the odd fiddly cut you actually need a power tookl for, some folks perfer the bolster and then a smaller angle grinder for the finer cuts they require. I did mine with just the mitre saw but it is hard to get all the cuts done as its not very flexible.

You should be able to find something in this internet age. Just match bore size, spin direction and speed rating. You could maybe get away with a 180 so long as the speed rating is high enough.

180 is fine, you cannot get a clean cut through it width ways but the blade will just pierce the middle so when you flip it over its dead easy to line up.


for a mitre saw you need a 30mm bore, or mine did and this is what makes sourcing blades hard.

I used the securing pilar on my saw (no idea what its called) to secure a second brick to the side at half a brick length, so when I got a brick to cut I just slid it up to that and cut, flipped it over sliding it back to this so it was all aligned and cut the other way. This worked well and helped keep my speed up as it saved measuring each brick.

Wow! Lot's of replies - thanks for the advice!

Turkey - will try that blade... as you said, it's a fiver so worth trying...

I did end up finding a mitre saw/blade combo that works, and ends up costing £100ish for the saw and £20 for each blade... so is at the limit of my budget... (and still cheaper than rentinig).

Didn't consider the bolster approach - trying to get any bevel angles with a bolster is far out of my skill range (and cutting 200+ bricks will inevitably end up with a hammer on my hand )

Will post my build momentarily!

I soaked the bricks in water and also had a small water spay onto the blade whilst it was in use to keep it all clean and cool and that wored really well for me, I uses a 1.5 litre plant spray bottle.

[spinal]

Tempted to try an alternative... I can find a cheap 210mm saw for £30 or so, and a 200mm blade, which can be found reasonably easily... 200mm blade should cut through 7-8 of brick in one cut...

In theory...

i got a cheep miter saw in market . and three 230mil diamond dry blades in lidl 6.50euro each i am 4 brick from top of dome . its going great so far i am one blade down on my 2nd now .. just got a tool maker to make hole bigger in diamond blade... i used water on first blade but have not used water at all on this one. a well only 7 euro a blade..

I would check any cheap mitre saw you find to know the blade bore, this is the size of the hole in the middle of the blade it accepts. Then check what blades you can easily find, I think you want a bore size more like 25mm rather than 30mm to get decent cheap diamond blades.
