HL series tricone bit is suitable for high--speed deep wells and long-life complex drilling requirements,such as horizontal wells,directional wells and branch wells,can work with mud motor.

Applicable rock types:
Low compressive strength, high drillability and very soft formations, such as shale, clay, sandstone, conglomerate, etc.

HQK 5 1/2" IADC 517 tricone bit  is composite sealed,suitable for high rotary speed.It can be applicable in low compressive strength,high drill-ability and soft formation,like shale,clay,sandstone,soft limestone,salt rock,etc.
