Specifications
This model of cone bit leg is specifically designed for trenchless rock drilling tools. Different cone tooth profiles can be selected and customized according to the customer's specific engineering conditions.
Product Features
Bearing
This series of bits adopts a floating bearing metal seal structure suitable for high rotational speeds, and applies a new type of synthetic lubricating grease to improve the bearing's working environment, providing longer service life and higher reliability under mud motor drilling conditions.
Additional Information
Design Features and Structure
1. Alloy reinforcement on the back of the leg prevents excessive wear of the leg back caused by rock mass during horizontal drilling.
2. In view of the fact that the leg tip is prone to wear during horizontal or directional construction, high-wear-resistant alloy material is hardfaced on the leg tip and the entire edge of the leg back, giving it better protection and wear resistance, reducing bearing exposure and damage caused by premature wear of the leg tip, and improving the service life of the drilling tool.
