Steel Body PDC
Use high-quality steel to make the base material of PDC bit, the surface of the blade weld high-performance
wear-resistant materials,

it can be widely used for Oil&Gas Drilling,Mining,Water Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit

1. High temperature and wear resistance
2. Godd quality reasonable price and after-sale service
3. IADC code suitable for different formation

1.Suit for drilling medium to medium-hard formations
2.Evolute asymmetrical blade cutter design
3.Combined utilization of high performance PDC bits

High temperature heat treatment forged alloy steel. Carbide teeth with high strength and toughness work more efficiently

Matrix body fixed cutters are made from tungsten carbide material. This provides
improved wear resistance and erosion.Additionally, they are typicall
