Roller cone drill bits can be divided into single cone, double cone, three cone Tricone bits and multi cone drill bits according to the number of cones. The most commonly used and common drill bits at home and abroad are three cone Tricone roller rock bits, namely TCI bits. In the oil, geology and various drilling industries, the roller cone drill bit is an indispensable and important part.

We mainly produce Tricone Drill Bits TCI Bits for open pit mining.

i). Type: Tungsten Carbide Insert (TCI).

ii). Formation Application: Soft to Hard Formation.

iii). Size Available: 3 7/8”~26”.

iv). Popular IADC Code: IADC415, 435, 447, 517, 532, 535, 545, 632, 635, 645, 725, 732, 735, 745, 825, 835, 845.

‌Specifications‌:

Tricone drill bits’ models and size specifications are very diverse to meet the needs of different drilling projects. Tricone bits have a wide range of sizes, from small sizes such as 3 7/8″ (98mm) to larger sizes such as 16″ (406mm), 17 1/2″ (445mm), 26″ (660mm) etc., and even larger sizes such as 1200mm, 900mm, 600mm, etc. are also available. These sizes cover the needs from smaller drilling to large projects.

Formation:

TCI bit can adapt to a variety of formations from soft to hard. Its working principle is to alternately contact the bottom of the well through the cutting teeth, with small rock breaking torque, small contact area between the cutting teeth and the bottom of the well, high specific pressure, easy to eat into the formation, and a large total length of the working blade, so it is relatively less worn and can adapt to various terrains.

Design:

Some Tricone bits are designed with special alloys to enhance the wear resistance and anti-seizure ability of the bearings, such as radial sliding bearing design, wear-resistant alloys welded to the jaws, and special alloys welded to the inner hole of the roller to improve the wear resistance and anti-seizure ability of the bearings. These designs make the roller bits excellent in withstanding drilling pressure and adapting to complex formations.

In addition, Tri-cone bits can also be customized according to specific needs, including processing and customizing different models of assembled drill bits with sizes ranging from 500mm to 1200mm to meet the needs of specific projects.

These characteristics make Tricone roller rock bits as one of the widely used drill bit types in drilling projects.
