Description of road milling bisRoad milling bit is made from carbide tips and steel body. Our tip material is tungsten carbide and cobalt. Tungsten carbide is very hard and wear-resistant but it is very brittle; cobalt is soft but it can bond the tungsten carbide participates together firmly. Combining with soft cobalt forms the high hardness and wear-resistance carbide steel, this carbide steel can withstand powerful impact load. RP18 bit is apply for small milling machine and it is suitable for cutting soft to medium hard asphalt road milling.
