Overview of Tricone Drill Bit

 

The 6''152mm IADC 117 Milled Tooth Tricone Roller Bit is a reliable solution for drilling in very soft formations. This bit is designed for use in applications such as water well drilling, oil & gas well drilling, and geothermal drilling.

It is equipped with milled steel teeth that offer durability and a consistent penetration rate. The bit features an elastomer sealed bearing to ensure smooth operation by preventing mud fluid from entering the bearing system.

The bit comes with three jet nozzles for optimal fluid distribution, cleaning the cones during the drilling process. Gauge protection and shirttail protection are available to further extend the life of the bit.

With an operating range of RPM 180~60 and WOB 0.3~0.75 kN, this tricone roller bit performs well in very soft formations like clay, mudstone, and chalk. It’s ideal for drilling projects that require high drillability and low compressive strength formations.

As a trusted manufacturer and supplier, HJ Bit offers cost-effective solutions and excellent aftermarket services for clients worldwide. The product is available for sale and can be customized based on specific needs.
