Tricone bits, first created during the Great Depression, represented a significant leap forward in drilling technology. Tricone drill bits are the go-to solution for almost any well digging, from everything to simple water wells to industrial scale oil extraction. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. Most tricone bits are either Mill Tooth bits, or TCI bits (TCI stands for Tugnsten Carbide Insert), and there is an ideal tricone bit for soft, medium, or hard rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.
Soft rock formations consist mainly of sand, clay, limestone or shale and are ideal for drilling with Mill Tooth Tricone bits. When working with soft formations you can use either sealed bearing or open bearing mill tooth tricone bits, depending on the scope and duration of your project. Sealed bearing tricone bits are longer lasting, but generally more expensive due to the precision work required to protect the bearings. Open bearing bits, on the other hand, are not as well protected and will wear out more quickly, however they are cheaper to manufacture. Tricone bits designed for soft rock generally have longer protruding teeth, [A" shaped teeth, or chisel shaped buttons. In all cases the teeth will be more widely spaced for tricone bits that are designed with soft formations in mind.
If you`re drilling in calcites, dolomites, hard limestones, and some hard shale you`ll need a tricone bit designed for medium rock formations. You may want a TCI Tricone bit. To better understand why tungsten carbide is ideal it`s useful to know about its properties. First discovered in 1927, Tungsten carbide is an exceptionally strong and hard material, this allows it to withstand higher speeds for more rapid drilling. Additionally tricone TCI bits are much more capable at absorbing the significant amounts of heat generated without damaging the tricone drill bit. Medium formation bits have teeth that are far closer together than what you see with soft formation drill bits. Additionally the teeth are less protruding, although they may still come in a similar range of shapes.
Hard rock formations are hard and abrasive formations usually made up of hard shale, calcites, mudstones, chert, pyrite, granite, quartzite, and cherty lime stones. The difficulties of drilling in this material make a TCI tricone bit all but mandatory. The exceptional hardness and strength of TCI [buttons" for the drill bits allow them to endure very difficult drilling conditions. As with all tricone bits there is an option between sealed bearing and open bearing. Sealed bearing bits are considerably more protected from wear and tear and therefore suitable for much more use before being replaced. Gauge protection can also significantly increase the lifespan of a tricone drill bit. Bits designed for hard formations continue the trend of less protruding teeth placed closer together. The teeth will be very short and placed very closely together. This results in a much slower drilling speed than you would get with medium or soft formation drill bits, however if you are drilling through hard rock strata you don`t have much choice.
Hopefully the above information has given you an idea of which tricone bit is ideal for the various rock formations you may have to contend with. For particularly advanced or ambitious projects you will want to carefully consider the type of tooth, additional kinds of seals, the importance of gauge protection, and estimated duration of the project in addition to the rock formation.

Since the earthquake in Japan, the Fukushima nuclear power plant leakage accident has almost occupied the headlines of major newspapers. The people of the world are holding their breath and are watching every dynamic of the Fukushima nuclear power plant event. However, few media have noticed that after the major earthquake, Japan’s wind power stations were almost intact, and at the most critical moment, continued power was supplied to this devastated country. Although many opponents of wind power claimed that the local wind power facilities could not be preserved in this major earthquake and the tsunami triggered by them, these wind power stations actually used facts and powerful counterattacks to counteract this kind of "deterrence."
Kamisu wind power station was only 300 kilometers away from the epicenter of the earthquake. However, after the most severe earthquake in Japan’s history, the wind power station “survived†and continues to generate electricity, especially after the accident at the Fukushima nuclear power plant. Since wind power plants do not have to be built where there is water, the risk of accidents is much less. Therefore, after people have witnessed the serious consequences of the accident at the Fukushima nuclear power plant, this simple and safe feature is even more valuable.
Yoshinori Ued, chairman of the Japan Wind Power Association, said after the earthquake that it had not received any reports of wind power stations damaging the earthquake and tsunami. Even Kamisu wind power stations that are not far from the epicentre of the earthquake are intact. If the Fukushima nuclear power plant delivered a bad answer in the earthquake test, then the Kamisu wind power station delivered a satisfactory answer and its excellent seismic design played a significant role.
Yoshinori Ued said that most of the wind power stations in Japan are currently operating at full capacity. The power companies even require some power stations to continue to increase power supply to ease the serious shortage of power supply in eastern Japan.
Eurus Energy is Japan's largest wind power company and has a 22% market share in Japan's wind power market. Recently, Eurus Energy announced that none of its 11 power stations in eastern Japan have been damaged by the earthquake. Eight of the power stations are operating normally, with a power generation scale of 174.9 megawatts. Three other nuclear power plants, including Kamaishi wind power station (42.9 MW), Takinekoshirai wind power station (46 MW) and Satomi wind power station (10.02 MW) were destroyed due to the earthquake. The power grid facilities in these areas are currently at a standstill.
Eurus Energy also said that these decommissioned wind power stations will soon be put into use again. Interestingly, Eurus Energy is the subsidiary of Tokyo Electric Power Co., which was notorious for the Fukushima nuclear power plant accident. After the same disaster, both faced a completely different situation. It really deserves people to think deeply.
WHAT ARE TRICONE DRILL BITS USED FOR?
TRICONE DRILL BITS FOR SOFT ROCK FORMATIONS
TRICONE BITS FOR MEDIUM ROCK FORMATIONS
TRICONE BITS FOR HARD ROCK FORMATIONS
TRICONE BITS ARE IDEAL FOR SOFT, MEDIUM, AND HARD FORMATIONS.
When all the world's attention is focused on the nuclear power plant in Fukushima, Japan, when countries are arguing about the safety of nuclear power, few people notice that in this catastrophe, Japan’s wind power facilities are all safe. The land was preserved, and it contributed its own strength in the face of power shortages in Japan.
