Oil drilling stone material consists of Brown fused alumina, white fused alumina, silicon carbide and other materials. Brown aluminum oxide is one of the basic varieties of corundum abrasive. Such high abrasive hardness, toughness, abrasive made with it are widely used, is suitable for cutting high tensile strength metals, such as all kinds of General steel, malleable iron, bronze, etc.

Alumina, corundum double-sided stone. the above corundum abrasive hardness, toughness less than corundum, good cutting performance, which made abrasives, suitable for grinding, carbon steel, alloy steel, high speed steel and so on. Black Silicon Carbide double-sided stone ngular crisp, sharp, high purity, which is suitable for grinding of abrasives made of cast iron, non-ferrous metals, rubber, leather, plastic, wood, ore and non-metallic.
