Product Description

A tricone bit is a drill bit with a head that is divided into three main parts. The tricone bit consists of three rotating cones working inside each other and each with its own row of cutting teeth.
The product covers hole diameters from 200 to 311 millimeters (7 7/8" to 12 1/4" inches). Both air-cooled and sealed bearings are available, as well as various carbide grades and insert geometries with cutting structures optimized for all conditions.
Far Eastern drilling can produce wide range tricone bit that mostly used for the open-pit mine blasting drilling, the IADC code various from 4 series to 8 that covers mainly the usage for mining.
