Some Useful Information on Tricone Drill Bits

You should consider several factors when you are looking into tricone drill bits. The different types of tricone drill bits are designed for certain functions and you should understand this in order to benefit your drilling project.

In the well drilling industry, there drill bits that are widely used are the mill tooth tricone drill bits and the sealed bearing drill bits. These are used when drilling goes through soft rock formations like limestone, shale and clay. You will notice that mill tooth bits wear out faster than sealed bearing bits since they are open bearing tricones. Mill tooth bits are cheaper to manufacture than a sealed bearing since it does not need extra protection. It will save you more money using an open bearing tricone bit over sealed bearing tricone bits.

A tricone bearing that rotates without a seal is an open roller bearing. They are usually cheaper to manufacture. However, with this type of tricone bit design, you need to clear it of debris every couple hundred feet of drilling. It does not save on time especially if your drilling project is quite deep into the earth’s crust. They are great for shallow drilling and they are widely used when digging a couple hundred feet below the surface because they are cheaper to manufacture.

If you need a high speed bit, then the ideal one is the PDC or polycrystalline diamond compact bit. These can be used when drilling through rock formations that are highly consolidated like shale, limestone, and sandstone. Because the PDC bit is a specialty bit, it can be broken easily when use on rock formations it was not meant for. For any type of rock formation, you can always rely on the all purpose tricone drill bit. The PDC bit however is more ideal drilling through consolidated rock formations.

You get advantages using a tungsten carbide insert or TCI for the tricone drill bit. It has the ability to withstand heat so it is very suitable when drilling in harder rock formations. When drilling at high speeds using the TCi is ideal since it is very resilient.

It is very challenging to learn about tricone drill bits. The important facts given above about the different types of tricones should provide advantages to your drilling projects. 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.
