Some Useful Information on Tricone Drill Bits

When you are using tricone drill bits, there are several things you need to understand in order to use the best types. The different types of tricone drill bits are designed for certain functions and you should understand this in order to benefit your drilling project.

If you work drilling wells, then you know that the most common drill bits in use are the mill tooth tricone drill bits and the sealed bearing drill bits. Sometimes drilling goes through soft rock formations like limestone, shale, and clay, and in this situations the mill tooth and the sealed bearing drill bits are commonly used. You will notice that mill tooth bits wear out faster than sealed bearing bits since they are open bearing tricones. However, when it comes to cost, mill tooth bits are cheaper since they don’t have extra protection like the sealed bearing bits. It will save you more money using an open bearing tricone bit over sealed bearing tricone bits.

Open roller bearings are tricone bearings that rotate without a seal. They are usually cheaper to manufacture. The downside to this tricone bit design is that it needs to be cleared of debris every couple hundred feet of drilling. If you have a deep drilling project, then this could be very time consuming. If you are doing shallow digging then this is the ideal bit to use since they are relatively cheap.

If you need a high speed bit, then the ideal one is the PDC or polycrystalline diamond compact bit. This can be used efficiently when drilling through highly consolidated rock formations like shale, limestone, and sandstone. But if you use it for other rock formations, then it can easily be broken since it is a specialty bit. The tricone bit is an all purpose bit which can be used for all types of rock formations. But when you are drilling through consolidated rock formations, you should consider the PDC bit.

You also benefit from using TCI or tungsten carbide inserts for the tricone drill bit. Because of its ability to with stand heat, the TCI is ideal when drilling in harder rock formations. It is more ideal than a traditional tricone because of its resiliency which makes it handy when drilling at high speeds.

It is very challenging to learn about tricone drill bits. If you understand the different types of tricone bits, then this could prove to be very beneficial to your drilling project. If we summarize what we have discussed above, it falls into four important considerations names, the advantages of using open bearing over a sealed bearing drill bit, the benefit of open roller bearing for shallow drilling projects, the circumstances when using a PDC bi is more beneficial than a traditional tricone bit, and the benefits of using a TCI insert on your tricone drill bit.
