Modified Onshore Bits
Typically, a used tricone bit that would be classified as an onshore bit would have its legs and body modified to fit a clamp type of drill collar. In doing this, they may run new bearings and do anything else required to make it a good clamp bit.
Used TCI Offshore Bits
An offshore bit is one that would be used in a water body. These bits are quite expensive because there is a high level of difficulty in making drill holes in water. Sometimes, to make bits more economically feasible, the body and legs of a bit are modified to make it suitable for offshore drilling.
Used Air Bits
Air bits are commonly used in dry, hard rock areas, but they may also be employed in zones with high pockets of petroleum. Standard mud bits have no internal mechanisms for dealing with air except for the hole at the back of the bit, so doing an air bit usually involves putting a lot of internal hosing in the bit to get the air circulation working correctly.
Used Tricone Water Well Bits
When looking for water in the soil or in rocks, drillers frequently use water well bits to drill. They are sometimes used in seismic subduction zones where crevices can be found, and there is no need for a large quantity of sample material. If there is a need to modify these bits, it can be done by quickly coupling undersized pins on the legs, a standard coupling on the body, and running standard bearings.
The tricone TCI drill bit combines high efficiency with versatility, proving effective across a range of industries.
When it comes to picking the right used tricone drill bits, it is important to look beyond the appearance and focus on critical aspects that impact performance. Identifying the type of bit is the first step in choosing. As mentioned earlier, there are numerous new and used TCI Tricone drill bits, each tailored for specific geographical features. For example, if the aim is to drill through soft soil or clay, an air-circulated bit could be the chosen one.
The next step is to inspect the drill bit visually. Look closely at the used drill bit. Ensure there is no crack or bone fracture that could affect its performance. Check for missing teeth or damage to the present ones. Inspect the ball bearings and seal systems for any visible damage. If possible, weigh the drill bit to see if an internal issue could emerge later. A drill bit that is significantly heavier than its weight is likely to have internal problems.
The operational parameters of the drill site should be in line with ideal drill bit selection. The temperature, pressure, and mud flow also matter. Match these with the drill bit specifications to ensure seamless operation on-site.
Regardless of where the used drill bit is being purchased from, it is always better to conduct a background check on the suppliers to ensure that their product does not further damage the business's reputation. Read reviews, check ratings, and, if possible, connect with previous customers to learn more about the supplier.
Finally, buying in bulk could provide some benefits. Negotiate the pricing of the bits if buying a larger quantity. Ensure terms and conditions for any return policy are clearly discussed and settled in writing to avoid any misunderstandings later on.
Q1: What are TCI bits?
A1: TCI bits are teeth-coated tricone bits. They are high-abrasion-resistant bits that use tungsten carbide inserts as teeth.
Q2: What are some advantages of used tricone bits?
A2: The main benefits of using used tricone bits include cost-effectiveness, established performance, rapid availability, and low environmental impact.
Q3: What are the three main forces that cut rock in drilling using used tricone bits?
A3: The crushing, shearing, and fracturing actions make the rock break. The crushing action is the result of the movement of the used tricone rock bit teeth. The shearing action comes from the comb-like teeth of the bit, which slice through the rock layer. The fracturing action is the result of the pressure generated when the bit drills into the ground.
Q4: What parts make up a used tricone bit?
A4: Used tricone bits comprise three main components—bearing seal, cone, and body. The bearing seal is the part that prevents fluid from entering the bearing. The body is the part of the bit that connects to the drill string and houses the cones. The cones are three rotating elements that crush and break the rock material.
