1. High temperature heat treatment forged alloy steel
2. Carbide teeth with high strength and toughness work more efficiently
3. Tooth palm lip hard welding surface with hard alloy ,Effectively prevent the drill bit wear and tear work
4. Head OD protection to effectively reduce head wear in abrasive formation and extend bit work
5.Directional jet enlarges lateral flow area and helpful bottom hole cleaning and increase of ROP
6. Lubricating system protection of bearing and seal system of bit extend bit work life7.API REG Connection
8.Rubber sealed and metal sealed bearing
