thread button bit FOB price China manufacturer

Thread button bits are among the most widely used rock drilling tools in mining, tunneling, quarrying, and construction. For international buyers, sourcing high-quality thread button bits from China at competitive FOB prices has become a strategic advantage. This article provides a comprehensive guide to thread button bit specifications, FOB pricing from Chinese manufacturers, and practical tips for selecting the right supplier.

What Are Thread Button Bits?

A thread button bit is a top hammer rock drilling tool that connects to drill rods through a male-female threaded connection. The threaded joint creates a rigid, high-torque coupling capable of transmitting percussion energy efficiently across long drill strings. The bit face features multiple tungsten carbide buttons that crush and chip away rock formations as the bit rotates under high impact force.

Thread button bits are the standard choice for production drilling, deep-hole applications, and any project requiring multiple rod extensions. They typically cover a diameter range from 32mm to 127mm, making them versatile across various drilling scenarios.

Thread Types: R-Thread vs T-Thread

Thread button bits come in two primary thread families, each suited to different drilling conditions:

• R-Thread (R25, R28, R32, R35, R38): Features a smaller pitch and rope-thread profile. Commonly used in smaller diameter bits (33mm–76mm) for drifting, tunneling, and shallow quarry operations. R32 is the most popular size for general rock drilling.
• T-Thread (T38, T45, T51): Uses a trapezoidal thread profile with larger pitch, providing higher torque transmission capacity. Designed for larger diameter bits (64mm–127mm) and deeper holes in production mining and bench drilling. T38 and T45 are widely used in medium to hard rock formations.

Thread Button Bit FOB Price Guide from China Manufacturers

The FOB (Free On Board) price of thread button bits from Chinese manufacturers varies based on diameter, thread type, button quality, and order quantity. Below is a general price reference based on current market data from major Chinese manufacturing hubs including Shaanxi, Shandong, Fujian, and Zhejiang provinces.

Key Factors Affecting Thread Button Bit FOB Price

• Carbide Button Grade: Premium tungsten carbide buttons (YG11C, YG13C) with higher cobalt content provide better impact resistance and wear life but increase material cost by 15%–25% compared to standard grades.
• Steel Body Material: High-quality alloy steels such as 23CrNi3Mo or 40CrNiMo undergo specialized heat treatment processes. Better steel grades improve fatigue resistance and extend bit life, adding 10%–20% to the base price.
• Bit Diameter and Face Design: Larger diameter bits and complex face designs (retrac, ｄｒｏｐ center) require more raw material and longer machining time, directly affecting the unit price.
• Order Quantity: Most Chinese manufacturers offer tiered pricing. A single pallet order (100–200 pcs) can reduce per-unit cost by 8%–15% compared to small trial orders.
• Customization: Custom thread profiles, special button configurations, or branded packaging add to the manufacturing cost but provide tailored solutions for specific drilling conditions.
• Certification Requirements: Products requiring ISO, API, or third-party inspection certificates may incur additional testing and documentation fees.

Why Source Thread Button Bits from China?

China has become the world's largest producer and exporter of rock drilling tools. Several factors make Chinese manufacturers the preferred choice for international buyers:

• Cost Advantage: Chinese manufacturers benefit from an integrated supply chain, from raw tungsten carbide production to finished bit assembly, resulting in FOB prices 30%–50% lower than European or North American equivalents for comparable quality.
• Manufacturing Scale: Major Chinese drilling tool manufacturers operate dedicated production lines with CNC machining, automated brazing, and heat treatment facilities, ensuring consistent quality across large order volumes.
• Customization Flexibility: Chinese factories are highly responsive to OEM requirements, including custom thread types, button configurations, face designs, and private-label packaging.
• Technical Expertise: With decades of experience supplying global mining and construction markets, established Chinese manufacturers understand international quality standards and can provide technical support throughout the procurement process.
• Logistics Efficiency: Well-developed export infrastructure at major Chinese ports (Shanghai, Ningbo, Qingdao, Xiamen) ensures reliable FOB shipping to destinations worldwide.

How to ｓｅｌｅｃｔ the Right Thread Button Bit for Your Project

Choosing the correct thread button bit is critical to maximizing drilling efficiency and minimizing operational costs. Here are the key selection factors to consider:

1. Assess Rock Formation Hardness

• Soft to Medium Rock (Mohs 1–4): Use ballistic or semi-ballistic carbide buttons for faster penetration rates. Convex face designs work well in these conditions.
• Medium to Hard Rock (Mohs 5–7): Semi-spherical buttons on a flat face design provide balanced performance between speed and durability.
• Hard and Abrasive Rock (Mohs 7–9): Spherical buttons with retrac body design maximize wear resistance and reduce the risk of bit jamming in fractured formations.

2. Match Thread Type to Your Drill Rig

Always verify the thread specification of your drill rods before ordering. R32 and T38 are the most commonly used thread types for medium-range drilling. R25 is suitable for light-duty handheld drilling, while T45 and T51 are designed for heavy production drilling rigs.

3. ｓｅｌｅｃｔ the Right Bit Diameter

Bit diameter should match your target hole size and be compatible with your drill string components. Remember that larger diameter bits require more powerful drill rigs and higher torque capacity at the threaded connection.

4. Consider Flushing Requirements

Effective flushing is essential for removing rock cuttings and cooling the bit face. Ensure the bit has adequate flushing holes and that your drilling system can supply sufficient air or water pressure. Retrac button bits are specifically designed with enhanced flushing channels for problematic formations.

5. Evaluate Total Cost of Ownership

While FOB purchase price is important, the total cost of ownership includes bit lifespan, penetration rate, downtime for bit changes, and regrinding costs. A slightly more expensive premium-grade thread button bit can often deliver lower cost per meter drilled than a budget alternative.

Conclusion

Thread button bits are essential rock drilling tools for mining, tunneling, quarrying, and construction projects worldwide. Sourcing from China offers significant cost advantages, with FOB prices ranging from approximately $12 to $95 per piece depending on thread type, diameter, and specifications.
