10-5/8" IADC 635 Tricone Roller Bit For Mining
The tricone bit is a common drilling bit with a wide range of uses and high mechanical drilling speed.
It is a bit body consisting of three roller cones assembled and welded together and fitted with a connecting screw.
The teeth of a tricone drill bit can be adapted to various types of formations by choosing different designs and types of bearing according to the hardness of the formation.
12-1/4" IADC 635 Tricone Roller Bit For Mining is designed for medium hard and abrasive formation with high compressive strengths such as limestone, sandstone, dolomite, and chert.
