Different Kinds of Tricone Bits for Sale

Regardless of whether you’re drilling a complex oil well or simple water well, it’s essential to have the right tools. Fortunately, tricones can be tailored to the drilling scenario, rock formation, or drilling speed that your project requires. What’s more, modern tricones are made with open or sealed roller bearings, and feature different drilling surface materials. With this being said, each have their advantages and disadvantages, and it’s important to understand these in order to pick the correct tricone bits for sale. In this article, we’ll explore these issues.

Open Roller Bearing Tricones

Open roller bearings tricone bits for sale allow the bearings to rotate without a seal. This makes them less expensive to produce, and therefore, cheaper to buy relative to other options. These types of tricones are ideal though for shallow drilling, where you only have to clean the tricones once or twice – or maybe not at all depending on depth. Some open roller bearing tricones have the ability to blast air through them to help clear away debris. This makes the cleaning process much easier, but it can add to the cost of tricone bits for sale.

However, keep in mind that they may require more maintenance. This is because debris can enter through the open cone and potentially lock up the bearings, which can lead to costly delays. It’s not unusual for open roller bearing tricones require cleaning every few hundred yards, which, again is why they’re better for shallow drilling.

Sealed Roller Bearing Tricones

Sealed bearing tricone bits for sale are designed to protect the rotating bearings from debris to allow for longer drilling durations. They’re relatively more expensive, but on some projects, the trade-off is well worth it since less time needs to be spent on cleaning and maintenance — especially compared to open roller bearing tricones. The bearings are generally sealed with an O-ring, and provide more lubrication to ensure the bearings keep going longer. This makes sealed bearings an obvious choice for any substantial or deep well drilling project.

TCI Tricones

TCI (Tungsten Carbide Inserts) feature superior hardness and durability, making them some of the longest lasting tricone bits for sale on the market. Furthermore, these tricone bits for sale offer exceptional value due to the quality of the materials used, which makes them ideal for any long term drilling projects. As with all tricone bits, you can opt for sealed or open roller bearings to best suit your project.

PDC Bits – An Alternative to Tricones

A comparatively new innovation, PDC (Polycrystalline Diamond Compact) drill bits can be used at higher speeds to complete projects in short order. The industrial-grade synthetic diamonds have exceptional strength; however, they’re also more brittle, which can lead to drill bit damage in some rock formations. PDC drill bits are best suited to large scale and potentially very expensive drilling projects, where the superior hardness and drilling speed will have time to offset the initial costs.

How to Extend the Use of Your Tricones or PDC Bits

Occasionally while drilling, your bit may shift slightly off center and risk making contact with the borehole wall with significant force. This can result in increased instability, drilling at an undesired angle, or damage to the drill bit itself. Fortunately, gauge protection may be able to prevent these adverse consequences.

Gauge protection is an insert that prevents the cutting elements from coming into contact with the borehole walls. Essentially, it controls the first point of impact for the tricones (or other bit) in the event that the drill begins to go off center. This can increase the life span of your tricone bits for sale, which is always a welcome benefit no matter what kind you are using.
