If you are sourcing TCI tricone bits from China, the FOB (Free On Board) price is likely the first number you will see on a quotation. But what does that number actually cover, and what should you realistically expect to pay for a quality tricone bit in today's market? This article gives you a clear, no-nonsense breakdown of FOB pricing for TCI tricone bits — from small water well bits to full-size oilfield models — so you can budget accurately and negotiate with confidence.
FOB stands for Free On Board. Under FOB terms, the seller is responsible for getting the goods to the designated port of departure and clearing them for export. Once the goods cross the ship's rail at the port, all risk and further costs — including ocean freight, insurance, import duties, and inland delivery at the destination — transfer to you, the buyer.
For TCI tricone bits shipped from China, an FOB quotation typically includes the cost of the bit itself, domestic transportation to the port (usually Shanghai, Tianjin, or Qingdao), export documentation, and port handling charges. It does not include international shipping, destination customs clearance, or local delivery. Understanding this distinction is essential when comparing prices from different Chinese manufacturers — a lower FOB price from one supplier may look attractive, but if their nearest port incurs higher inland freight or their export paperwork is frequently delayed, the total landed cost could end up higher.
TCI tricone bit prices vary widely depending on the bit's diameter, material grade, IADC code, and intended application. The table below provides realistic FOB price ranges for new bits from Chinese manufacturers as of 2025, based on common specifications seen in the market.
| Bit Size | Typical Application | IADC Code Examples | Approximate FOB Price Range (USD) |
|---|---|---|---|
| 3" – 4" (76mm – 102mm) | Water well, small borehole drilling | 417, 427, 437 | $150 – $400 |
| 4 1/2" – 6" (114mm – 152mm) | Water well, mining exploration, geothermal | 437, 517, 537 | $300 – $800 |
| 6 1/2" – 8 1/2" (165mm – 216mm) | Oil and gas drilling, deep water wells | 537, 617, 637 | $600 – $2,500 |
| 9 1/2" – 12 1/4" (241mm – 311mm) | Oilfield, large-diameter boreholes | 617, 637, 737 | $1,500 – $5,000 |
| 13 3/4" – 17 1/2" (349mm – 445mm) | Large oil and gas wells, foundation drilling | 637, 737, 837 | $3,000 – $12,000+ |
Note: Prices are estimates for new, standard-configuration bits with open bearings. Sealed bearing bits, API-certified bits, and bits with specialized ｉｎｓｅｒｔ patterns may cost 20%–50% more.
Not all TCI tricone bits are created equal, and several factors explain why two bits of the same diameter can differ significantly in price. Understanding these variables helps you avoid overpaying for features you do not need — or underbuying a bit that will fail prematurely on a demanding job.
The bearing system is one of the biggest cost drivers. Open bearings are simpler and cheaper, but they allow drilling fluid and debris to enter, which shortens service life. Sealed roller bearings use high-temperature grease and protective seals to keep contaminants out, significantly extending the bit's operational life. A sealed-bearing bit can cost 30%–60% more than an open-bearing equivalent, but for deep or high-cost drilling operations, the longer run time more than justifies the additional expense.
The "TCI" in TCI tricone bit stands for Tungsten Carbide ｉｎｓｅｒｔ, and the quality of these inserts directly affects both performance and price. Fine-grain, high-purity tungsten carbide grades (such as YG8 or YG10) offer superior wear resistance in hard formations but cost more than standard grades. Additionally, bits with more inserts per cone or with specialized ｉｎｓｅｒｔ shapes (chisel, conical, or hemispherical) require more material and machining time, increasing the cost per unit.
The bit body is typically made from alloy steel, and the specific alloy composition matters. Premium bits use nickel-chromium-molybdenum alloy steel for enhanced strength and corrosion resistance. The manufacturing process also affects cost: bits that undergo CNC precision machining, multi-stage heat treatment, and ultrasonic weld inspection cost more to produce but deliver more consistent performance in the field.
Bits destined for oil and gas drilling often require API (American Petroleum Institute) certification to meet industry standards. The certification process involves third-party testing and documentation, which adds to the per-unit cost. For water well or construction applications, ISO 9001 certification is usually sufficient and more economical.
Like most industrial products, tricone bit wholesale pricing is significantly more attractive than single-unit purchases. A contractor buying one or two bits for a small project will pay close to retail price. In contrast, a drilling company placing a bulk order of 20–50 bits can typically negotiate a 10%–25% discount on the FOB price. Some manufacturers also offer tiered pricing: the more you buy, the lower the per-unit cost. If your project requires a steady supply of bits, establishing a long-term supply agreement with a manufacturer can lock in favorable pricing and ensure consistent availability.
As a manufacturer based in Xi'an, China, with over a decade of experience in the drilling tools industry, Xi'an Heaven Abundant Mining Equipment CO.,LTD (TY Drill Bits) offers competitive FOB pricing on TCI tricone bits across a wide range of sizes — from 3-inch water well bits to 12 1/4-inch oilfield models. The company's FOB prices are structured to give buyers maximum value at every order size.
Several factors contribute to TY Drill Bits' ability to offer competitive pricing. First, the company operates its own production line and sources materials directly, cutting out middlemen and reducing raw material costs. Second, with an export ratio exceeding 90%, the company has streamlined its logistics and documentation processes, which means lower handling costs and faster turnaround at the port. Third, flexible payment terms — including T/T, L/C, and PayPal — make it easier for international buyers to manage cash flow while securing the bits they need.

All products are manufactured under ISO 9001 quality management standards, and the company's team is experienced in preparing export documentation for destinations across the Middle East, Africa, Southeast Asia, South America, and Europe.
Pro Tip: When requesting an FOB quotation, always specify the bit diameter, IADC code, bearing type (sealed or open), thread connection, and estimated order quantity. The more detail you provide, the more accurate the quote will be — and you will avoid surprises when the invoice arrives.
Getting an accurate FOB price for the TCI tricone bit that fits your project is straightforward. Reach out to TY Drill Bits with the following information:
The sales team at TY Drill Bits typically responds within one business day with a detailed FOB quotation that includes the unit price, port of loading, estimated production lead time (standard within 15 working days), and available payment terms. If you need a CIF (Cost, Insurance, and Freight) quote that includes shipping to your destination port, simply mention this in your inquiry.
The FOB price for a TCI tricone bit is not a single number — it depends on the bit's size, bearing type, ｉｎｓｅｒｔ grade, certification requirements, and the quantity you order. A small water well bit may cost as little as $150–$400 FOB, while a large API-certified oilfield bit can run into the thousands. The key to getting the best value is matching the bit specification to your actual drilling conditions, buying in bulk when possible, and working with a manufacturer that has proven export experience and transparent pricing.
TY Drill Bits, with its factory-direct pricing model and over a decade of international trade experience, is well-positioned to provide competitive FOB quotations for tricone bit wholesale orders of any size.
