What Tricone Drill Bits Should You Use?

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.

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. A mill tooth bit wears out faster than a sealed bearing bit since it is an open bearing tricone. However, when it comes to cost, mill tooth bits are cheaper since they don’t have extra protection like the sealed bearing bits. If you want to save on money, then use the open bearing tricone over the sealed bearing ones.

Open roller bearings are tricone bearings that rotate without a seal. 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.

The polycrystalline diamond or PDC bit is ideal for high speed drilling, and better than the traditional tricone bit. If you are drilling through highly consolidated rock formations like limestone, sandstone, and shale, then this is the ideal bit to use. But if you use it for other rock formations, then it can easily be broken since it is a specialty bit. The tricone drill bit is the best all-purpose bit and can be used for many different types of rock formations. But when you are drilling through consolidated rock formations, you should consider the PDC bit.

You get advantages using a tungsten carbide insert or TCI for the tricone drill bit. You can use it form drilling in harder rock formations since it has the ability to withstand heat. It is also very resilient which makes it very handy when drilling at high speeds and making it more ideal than a traditional tricone.

Learning about tricone drill bits is challenging but very interesting. If you understand the different types of tricone bits, then this could prove to be very beneficial to your drilling project. You now understand the advantages of using an open bearing or a sealed bearing drill bit, the benefit of open roller bearing for shallow drilling, the special circumstances when a PDC bit can be used over a tricone bit, and the value of the tungsten carbide insert on your tricon drill bit.

If you have drilling needs just visit triconebitsales British Columbia and there you can find a selection of new and used tricone bits available.
