牙轮钻头具有良好的structuralcharacteristics ：
1与滚动牙轮钻头密封轴承， cylindricalroller体滚动槽放置，在使用性能更好。
（2）在子牙轮钻头推力轴承surfacesrespectively抗磨治疗和硬化，硬化抗drillprotection 。
3使用可承受250 ℃的高温temperaturewear新的润滑脂阻力。
4使用压差极限andprevent钻井液进入润滑system.Improved conebitsoil胶囊全橡胶，轴承的润滑systemprovides了良好的保证。

双方的优势和PDC drillbits ，更多的三牙轮钻头比强度和延展性牙轮钻头是largeformations ，也可以适用于PDC钻头难以处理hardinterlayer和其他复合物的形成。

Cone bit with good structuralcharacteristics:
1 with the rolling cone bit sealed bearing, cylindricalroller body rolling groove is placed, , with better performance in use.
(2) In sub-cone bit thrust bearing surfacesrespectively antifriction treatment and hardening, hardening anti-drillprotection.
3 using can withstand 250 ° C high temperaturewear resistance of the new grease.
4 using the differential pressure limit andprevent the drilling fluid into the lubrication system.Improved conebitsoil capsule full rubber, the bearing lubrication systemprovides a good guarantee.

Tricone rock bit of both the advantages and PDC drillbits, tricone bit more than for both strength and ductility are largeformations, but also can be applied to PDC bit difficult to deal with hardinterlayer and other complex formation.
