Key Features of Used Tricone Bits
1
Improved strength and wear resistance by using carbide inserts with high strength.
2
Surface of high precision bearing heat treated to improve load capacity and service life.
3
Extended bearing life by adopting harder and more wear-resistant material for thrust bearings.
4
Preventing reflux structure avoids air counterflow and dust entry, protecting the bearing during stops.
5
Sealed roller bearing structure with rollers arranged in recessed grooves for increased journal size.
6
Hardfaced thrust bearing surfaces treated with friction-reducing technology.
7
Journal bearing with silver-plated cone bearing inlaid with friction-reducing alloy for superior seizure resistance.
Product Superiority
✓
Recyclable: Typically only consumes one-third of its lifespan in initial oil exploration.
✓
Durability: Withstands high WOB (Weight on Bit) under conventional drilling rates.

Frequently Asked Questions
Q1: What are used tricone bits typically used for?
A1: These bits are primarily used for water well drilling, oil and gas exploration, and mining projects where cost-effective drilling solutions are required.
Q2: How is the quality of a "90% new" used tricone bit?
A2: A "90% new" bit means it has only consumed a small fraction of its operational life. The tungsten carbide teeth and bearings are in excellent condition, offering performance close to new bits at a lower cost.
Q3: Can these bits handle hard rock formations?
A3: Yes, specific IADC types like the 617 are designed specifically for hard strata with high compressive strength, such as limestone and sandstone.
Q4: What is the benefit of the sealed roller bearing structure?
A4: The sealed structure prevents drilling fluids and debris from entering the bearing assembly, significantly extending the service life of the bit.
Q5: How do I choose between TCI and milled tooth bits?
A5: TCI (Tungsten Carbide Insert) bits are better for harder, more abrasive formations, while milled tooth bits are generally more economical for softer rock layers.
Q6: What is the MOQ for ordering these bits?
A6: The minimum order quantity is just 1 piece, making it accessible for both small projects and large-scale operations.
