Product Description

Product Description

 

8 1/2'' 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.

Steel tooth tricone 8 1/2'' 117 features

Rubber Sealed Bearing: Ensures long-lasting sealing to prevent mud fluid intrusion and guarantees smooth operation.
