"Wet blades" refer to a type of cutting tool or blade that is designed to be used with a liquid, typically water or a lubricant, to enhance cutting performance. This technique helps reduce friction and heat, allowing for smoother cuts and prolonging the life of the blade. Wet blades are commonly used in various applications, including woodworking, metalworking, and tile cutting. In the context of sawing, wet blades are often employed in diamond saws for cutting hard materials like ceramic tiles or concrete. The water not only cools the blade but also helps to minimize dust and debris, making the cutting process cleaner and safer for the user.
