Tricone ROCK Bit

These Tricone ROCK Bit are used to drill soft formation with low compressive strength and high drill ability, such as shale, clay, sandstone and soft limestone, etc. The tricone rock bit features a tungsten carbide rock engagement cone, replaceable carbide fluid ports and shirttail overlays, and strategically placed carbide buttons on the bit housing to extend the life of the tool.


The Tricone rock bit is one of the most efficient and reliable drilling tools in the industry.

The tricone rock bit is a highly specialized and durable drilling tool that has been designed with precision and engineering excellence. It is made up of three cones, each with rows of teeth that are arranged in a pattern to cut through even the hardest rock formations. The tricone rock bit is designed to rotate at high speeds, making it an ideal tool for drilling deep into the earth.

Each Rock Bit is made from the highest quality tungsten carbide steel and is precision machined to produce the perfect drilling tool. These bits are then heat-treated to the proper hardness, which helps achieve excellent surface compression and fatigue resistance. Manufactured in-house, each bit is specially machined to the desired shape and comes with the correct size Rock Bit.

With a wide range of sizes and configurations available, our tricone rock bits are suitable for a variety of drilling applications. Whether you are drilling for oil, gas, or minerals, our tricone rock bits are capable of delivering the performance and reliability that you need to get the job done.

We are proud to offer the tricone rock bit as part of our product lineup and stand behind the quality and performance of each and every one that we manufacture. Contact us today to learn more about how our tricone rock bits can help you achieve your drilling goals with speed, efficiency, and reliability.

1. Grand Tungsten carbide insert tooth sealed and gage protection journal bearing, hard faced head bearing surface.

Cone bearing inlaid with friction reducing alloy and then silver plated.

The load capacity and seizure resistance of the bearing is greatly improved

2. O-ring seal is made of the more wear resistance high saturated Buna-N with the section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.

3. The bit bearing is ball which can be applied to high rotary speed drilling.

4. All rubber compensator is used which can provides the bearing system with good assurance of lubrication

5. Grand new type of grease that can sustain high temperature up to 250C is utilized.

6. Grand high wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows, the exposure height and special shaped compacts.
