The tricone bit consists of three cones, each mounted on a bearing. These cones rotate independently, allowing for efficient rock fragmentation. The cutting elements on the cones can be either milled teeth or tungsten carbide inserts, depending on the application.
When the tricone bit is rotated, the cones roll and crush the rock beneath them. This rolling action minimizes wear on the cutting elements and distributes the load evenly across the bit. The design also facilitates efficient removal of drill cuttings, reducing the risk of clogging.

IADC 437 Tricone bit application:
The inserts work for Very soft formations with low compressive strength and high drillability, such as clay, mudstone, chalk, gypsum, salt, soft limestone, etc.
Geothermal Drilling:
Where wells are drilled into geothermal reservoirs beneath the Earth’s surface so as to extract heat for power generation purposes; these bits become essential tools for deep seated complex geological formations such as hard rocks among others. This includes tough layers of rocks to be cracked so as to reach desirable geothermal reservoirs.
Water Well Drilling:
Sand gravel bedrock are examples of geological formations that have different types penetrated by tricone bits during water well drilling operations. In addition, it has been observed that softer formation will yield higher ROP (Rate Of Penetration) while teeth or inserts that can withstand harder formation’s abrasivity come fitted on them.
