Choosing the Best Tricone Bits for Optimal Drilling Results

Tricones are used for numerous drilling jobs around the world, from making and forming water wells, to handling complex oil extraction operations. Depending on the project, different types of tricone bits are needed to complete the job. Regardless of the type of you need, be assured that there are tricones bits for sale that are suitable for the task at hand. The remainder of this article provides you with facts and advice to make the right choice.

Exploring the Different Types of Tricone Bits for Sale

Open Roller Bearings

Open roller bearings tricones are ideal for shallow drilling projects where occasional delays are tolerable to the overall project schedule and duration. All open roller bearing tricone bits for sale are designated with a 1, 2, or 3 as the third digit in their IADC code. 1 is for standard roller bearings, 2 is for air cooled bearings, and 3 is for open bearing with gauge protection.

Keep in mind, however, that open roller bearings have no seal, and as a result outside debris can potentially enter through the cone and interfere with the ability of the cones to rotate. What’s more, significant debris can jam tricones and force a halt in drilling while debris is removed. However, they remain popular due to their lower cost relative to other types.

Sealed Roller Bearing

Sealed roller bearing tricones are similar to open seal bearing tricones, but feature an O-ring that protects any debris from reaching the roller bearings via the cone. These tricones feature a grease or lubricant reservoir, which prevents any blockages caused by debris and keeps the bearings in motion. These factors make sealed roller bearing tricones an obvious choice for deeper drilling projects where time delays are unacceptable.

Keep in mind that, eventually, the O-ring will wear out. However, the tricones can still be used for some time as if they were open roller bearings. Sealed roller bearing tricone bits for sale are designated with a 4 or 5 as the third digit of their IADC code. 4 is for standard sealed roller bearings, and 5 is for a sealed roller bearing with gauge protection.

Journal Bearing

Journal bearing tricones bits for sale are suitable for robust projects, and can withstand a great deal of wear and tear. This is the most expensive option, and best suited to complex drilling projects. Journal bearings discard the roller bearings in favor of a “floating brush” seal, which is combined with lubricant to allow the roller-head to rotate without any exposure to outside debris.

Ideally, journal bearing tricone bits for sale can stand up to extremely prolonged and deep drilling sessions with minimal time spent on maintenance or tending to debris. Gauge protection is the norm with journal bearings, due to the types of projects these tricones are used on. After all, if a project requires the durability of journal bearing tricones, it stands to reason it will also require the durability offered by gage protection. Journal roller bearing tricones are designated with a 6 or 7 as the third digit of their IADC code. 6 is for a standard sealed journal bearing, and 7 is for a sealed journal bearing with gauge protection.

Suitable for Varied Rock Formations

As a final word of advice, keep in mind that, generally speaking, tricone bits are better suited for varied rock formations. The action of the individual rollers on a tricone bit serves to fracture the rock, making it significantly more flexible in terms of the range of formations that one bit can be used upon.
