The main composition of oil drilling stones is divided into materials such as brown corundum, white corundum, and black silicon carbide. Brown corundum is one of the basic varieties of corundum abrasives. This type of abrasive has high hardness and good toughness, and the grinding tools made from it are widely used, suitable for cutting metals with high tensile strength, such as various general steel, forging cast iron, bronze, and so on.

White corundum and brown corundum double-sided oil stone. This type of abrasive has a higher hardness than brown corundum and a lower toughness. It has good cutting performance and is suitable for making grinding tools for grinding alloy steel, high-speed steel, carbon steel, etc. Black silicon carbide double-sided oil stone. This type of abrasive is brittle and sharp with high purity. It is suitable for making grinding tools for grinding cast iron, non-ferrous metals, rubber, leather, plastic, wood, minerals, and non-metallic materials.
