All lapidary blades require some sort of lubricant. While diamonds will cut/grind most anything, they do fracture at very high temperatures. The more surface area of the rock in contact with the blade the higher the temperatures generated. Hence the larger the diameter of the saw blade requires more lubricating. What we are doing here is reducing the friction between the saw blade and the rock. Friction generates the heat. Friction is bad!

Graves Company has tested over the years many lubricants of all types. The three we offer to you exhibit the best properties for the intended use. See our charts below for a comparison of characteristics and our recommendations.
