Wet blades and dry blades have a variety of uses, performing differently based on their cutting surfaces. Using the wrong blade is a common mistake that can damage blades and even pose a safety hazard to the operator. Typically, a wet diamond blade performs better due to its ability to provide deeper cuts and reduce the possibility of overheating due to friction on cutting surface(s). Overheating blades can cause a variety of problems, including damage to the segments within diamond blades. As a user is cutting with a wet blade water is used to keep them cool during the cutting process. It also acts as a cleaning mechanism to keep fragments and dust at bay. Dry blades, on the other hand, are used in the absence of water or any other liquid. The life of a dry blade will tend to be signficiantly shorter than that of wet blades and will wear much quicker due to the intense heat and friction they are exposed to. Wet blades are often the tool of choice for construction workers and contractors because of their extended lifespan ability to withstand wear and tear. Typically, dry blades can be used as wet blades, but on the other hand, wet blades cannot be used as dry blades as they run the risk of being damaged.
