What kind of saw blade should I use?
It depends on a number of things. One of the first things you should figure out is the task you are going to use the blade for. Each blade is designed differently to accommodate specific tasks. So if you are wet cutting concrete, use a wet-cutting diamond blade. These blades are specifically constructed for use with water. If you are performing dry/indoor cutting applications, use a dry-cutting diamond blade.
Consider the type of saw you are using. If you have a saw with a high horse power, you should use a blade with a high diamond concentration, as it's a harder blade. If your saw has a lower horse power, use a diamond blade with a lower diamond concentration, as that indicates a softer blade. The type of material you are cutting is also important to keep in mind. If you are cutting tile, use an abrasive cutting blade. If you are cutting concrete, ceramic or glass, opt for a diamond blade. If you need to make rough, unfinished cuts, use a segmented blade. If you are wet cutting ceramic, tile or granite, use a continuous rim saw blade. Remember that if you use the wrong type of blade, you could end up damaging the blade or the material, or end up with an improperly cut work piece.
