Cutting fire bricks can be a bit challenging because they are made of dense and hard materials. Here are some steps to follow for cutting fire bricks:

1.Choose the right tool

The best tool for cutting fire bricks is an angle grinder equipped with a diamond blade. It's important to use a diamond blade as it can cut through the dense material of fire bricks. Other tools that can be used include a circular saw or a masonry saw.

2.Prepare the brick

Before starting to cut, mark the line where you want to make the cut using a pencil or marker. Make sure to measure carefully and mark the line accurately. Then, use a wire brush to clean any debris or dust off the surface of the brick.

3.Cut the brick

Put on protective gear such as gloves, safety goggles, and a dust mask before starting to cut. Then, position the brick on a stable surface and clamp it down securely. Turn on the angle grinder or other cutting tool and slowly cut along the marked line, applying even pressure to the blade. If using an angle grinder, use a back-and-forth motion to make the cut. If the blade gets too hot during cutting, cool it down with water.

4.Smooth the edges

After cutting, the edges of the brick may be rough or uneven. Use sandpaper or a grinding wheel to smooth out any rough edges and create a clean finish.
