The wet cutting blades are on the top, but you must add a low stream of water during the cut, this will lubricate the blade during the cutting process and also it will prevent the silica dust from being produced.
the dry cutting blades are specially designed so they expel the heat quickly by making segmented teeth on the blade. The best thing about this type is that it has a long life span but be careful, they produce high amounts of silica dust during the cut. Therefore, I advise you to wear a respirator or dust mask.
To be able to cut concrete with circular saw, the thickness must not exceed 15 cm max or things may become difficult.
Before we get started, you should follow these tips:
Wear all your protective gear.
Make sure the surface that you want to cut is clean.
Make sure you have the right blade and that the blade is not dull to avoid kickback.
Circular saw with the proper blade
Respirator or Dust mask
Step 1: Mark off the cutting path with the chalk line
Step 2: Adjust your circular saw to be aligned with the chalk line and have a cutting depth of 50mm and let it start to reach max speed.
Step 3: Start the cutting slowly and don’t force the blade or the circular saw, just let the machine do the cutting by itself and you do the feeding slowly.
Step 4: If you are cutting with wet blade, then make sure you have someone helping you add a slow stream of water to the blade during the process to overcome the heating and prevent the dust.
Step 5: Do not make a continues cut, stop the blade every 45 seconds and do it again.
If you want to cut in reinforced concrete, do not do it by yourself because of two reasons:
You will encounter rebar and things may not be good with you, you will need a professional.
Reinforced concrete is a structural element in your building, so be careful when dealing with it, because cutting the rebar inside the RC may cause cracks in other parts of the RC.
If you have a thickness larger than 15 cm try to cut the block from both sides and use the sledgehammer to make the block split.
