Cemented carbide button have their unique working properties and are therefore widely used in oil drilling and snow plowing, snow plow machines and other equipment.
Tungsten carbide mining inserts are also used in coal quarry drilling tools, mining machinery tools and road clearing snow removal and road maintenance tools. Tools used in quarrying, mining, tunneling, and civil construction.
It has superior wear resistance and impact toughness, and has higher drilling speed than similar products.
