Product Description

Tricone bit is one of the main tools for blast hole and water well drilling. Its life span and performance whether suitable for
drilling or not, that has an great influence about the quality, speed and cost of drilling projec

The rock breakage by the tricone bit which used in oilwell drilling or mining well are working with both the impact of teeth and the shear caused by slippage of the teeth, which bring high rock breaking efficiency and the low operation cost.

The roller cone bit is the most widely used tool in petroleum drilling and geological drilling. Tricone bit has the function of impacting, crushing and shearing rock in formation, so it can adapt to soft, medium and hard formation. The cone bit can be divided into milling (steel teeth) cone bit and TCI cone bit according to the type of teeth.
