We supply Tricones that are suited for Directional Drilling, Oil & Gas, Geo-Thermal & Water well, Construction, Horizontal Directional Drilling and Mining.
Gauge rows and inner rows are conical type:
Designed for soft formation with low compressive strengths such as shale,soft limestone,dolomite with interlayers and coal ore.
Application:15,000-23,000 PS(100-158MPa)
GX roller cone drill bits are designed with a reliable elastomer seal and a durable cutting structure to improve performance in a wide variety of drilling applications. The cutting structure's tougher carbide grades and compact shapes, coupled with field-proven G3™ bearings and leg protection, all combine to maximize penetration rates in rotary and motor applications.
