Refractory Brick Cutting

There are mainly two different types of fire and refractory bricks on the market, and United Diamond Tools (UDT) make blades for cutting them both.

Relatively soft, abrasive firebricks, as used on some pizza ovens and fire pits, can be cut with masonry diamond blades with a handheld angle grinder (very dusty), on an ordinary brick saw with water (preferable option).
See masonry diamond blades here and here.
(Tip: To reduce dust when dry cutting, try soaking a brick in water for a couple of minutes, then letting it drain for another couple of minutes before cutting. Ensure water does not enter your grinder.)

The industrial refractory bricks are a lot harder and denser.
For example, Shinagawa manufacture high quality dry-pressed alumina bricks ranging from 35 to 95 per cent alumina content. Higher content alumina blades are cut ideally with our ultra thin blades, or blades as below.
All are from our Korean supplier, who only make high quality, long life blades.
So if you are looking for a silent or non silent refractory brick cutting blade, give us a call at UDT.

Note - If you are cutting dry, always be aware of the danger of breathing in the dust.
Ensure a dust extraction system is used with a suitable filter fitted. Use a half face respirator or a PAPR (Powered air purifying respirator). Even if you are cutting wet, the slurry created can dry out and create a hazard for other users - dispose of slurry as per your local regulations.

Silica dust - when workers cut, saw, crush, drill, polish or grind products that contain silica, particles are created, which are one-hundredth of the size of a grain of sand. These can get  stuck deep in the lungs. 
Ensure precautions to limit exposure to dust are in place.
See the WA government's info on silica dust here.
