Specification
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. Our 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.

Product Application
Our tricone bits are mainly used for large-scale open-pit mining, such as open-pit coal mines, iron mines, copper mines, and molybdenum mines, as well as non-metallic mines.
With the increasing variety of types, they are also widely used in quarrying, foundation clearing, hydrogeological drilling, coring, tunneling in railway transportation, and shaft drilling in underground mines.
Manufacturing & Quality Control
With rich production experience, we use high-quality raw materials, advanced production technology, and strict testing means to produce excellent performance products. We can manufacture according to customers' samples or drawings.
