Guide to Tricone Drill Bits

You should consider several factors when you are looking into tricone drill bits. The different types of tricone drill bits have their own advantages and the best way to use them and this is important to understand.

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. These are commonly used when the drilling goes through soft rock formations including limestone, shale, and clay. A mill tooth bit is an open bearing tricone so it wears out faster than a sealed bearing bit. 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. Manufacturing these is very inexpensive. The downside to this tricone bit design is that it needs to be cleared of debris every couple hundred feet of drilling. This can be time consuming when drilling deep into the earth’s crust. If you are doing shallow digging then this is the ideal bit to use since they are relatively cheap.

The polycrystalline diamond or PDC bit is ideal for high speed drilling, and better than the traditional tricone 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. The tricone drill bit is the best all-purpose bit and can be used for many different types of rock formations. The PDC bit however is more ideal drilling through consolidated rock formations.

Tungsten Carbide Inserts (TCI) for the tricone drill bit can be beneficial. You can use it form drilling in harder rock formations since it has the ability to withstand heat. When drilling at high speeds using the TCi is ideal since it is very resilient.

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.
