TCI Tricone Bit Formations
TCI (Tungsten Carbide Insert) bits are designed for soft to very hard formations based on the carbide quantity and style. Applications include oil & gas, water well, geotechnical, construction, and mining.
Soft Formations (417, 437, 517, 537): Features large chisel-shaped inserts for high penetration in shales, clays, limestone, and sands.
Soft to Medium Formations (617, 637): Effectively drills through hard limestone, dolomite, and hard sands with cherty content.
Medium to Hard Formations (737): Designed for chert, granite, flint, and taconite with short, closely spaced inserts for wear resistance.
⚙

Frequently Asked Questions
How do I order specific products?
Please send an inquiry with the item description or Model/IADC number. Including the tricone bit size and drilling layer information will help provide an exact quotation.
What is the typical lead time and shipping duration?
Lead time depends on order quantity (usually 3-7 days for stock). Shipping from China to Europe takes about 25 days by sea, and to the US West Coast about 20 days.
Are the products manufactured to international standards?
Yes, all activities and products are accredited to ISO 9001:2008 and API standards to ensure quality satisfies international requirements.
What formations are the TCI bits suitable for?
We offer bits for soft formations (shales, clays), medium formations (limestone, hard sands), and extremely hard formations (granite, chert).
What materials are used in the construction of the bits?
The bits are made from high-grade alloy steel and feature premium tungsten carbide inserts (TCI) for maximum durability and penetration.
Can I request customized drilling bits?
Yes, special requirements for different models, sizes, and IADC codes can be customized to fit your specific drilling project needs.
