Material Hardness & Abrasiveness Materials have varying degrees of hardness and abrasiveness. Additionally, specific man-made and natural materials can differ greatly depending upon the exact physical composition. For example, glass varies in hardness depending upon color and type, since various metals and minerals are added to achieve the different types and colors. Glass also has differing degrees of “temper” depending upon the specific manufacturing methods used. Ceramics, ceramic tile, porcelain and porcelain tile are various forms of vitrified glass like material. They also have differing hardness and abrasiveness depending upon the type, composition, manufacturer and manufacturing methods used. The hardness and abrasiveness of natural materials, such as stone, vary by type, but they also vary significantly within a specific type. Most stones are not pure – they are mixtures of various types of rock. Granite, for example, contains various combinations of primarily qu

Choosing wet or dry may be a matter of user preference or job requirement. When using a power hand tool such as a power hand saw, it is not safe to use water because of the electrical power source. However for concrete saws, wet cutting is usually preferred because you can cut deeper when using water as a coolant. For tile and masonry saws, either wet or dry diamond cutting blades  can be used. For power cutters, dry diamond  blades are more popular, but they are often used wet to control dust. Wet diamond blades MUST be used with water. Dry diamond blades may be used EITHER dry OR wet, as the job or equipment allows. Dry diamond blade
