Audited Supplier The tricone bit consists of three rotating cones working inside each other and each with its own row of cutting teeth.
The tricone bit has three roller cutter cones with a series of teeth that crush rock on the rock face as they roll over the face.
A tricone bit is a drill bit with a head that is divided into three main parts
The way the tricone breaks through the rock is by using its multitude of very small chisel shapes, which protrude from a roller. These are pushed into the rock by the rods that connect it to the surface, and the weight is distributed evenly to break through.
