What Are the Advantages and Applications of Tungsten Carbide Insert Alloy Coring Bits Over PDC Bits?
This article explores the distinct advantages and primary applications of Tungsten Carbide Insert (TCI) coring bits compared to PDC coring bits. Focusing on formation adaptability, mechanical performance, and cost-effectiveness, it highlights why TCI bits are the preferred choice in hard, abrasive, and heterogeneous formations.
Optimizing Drill Bit Selection for Challenging Cobble Formations
Choosing the right drill bit is critical for efficient drilling in abrasive and unstable cobble layers. This article compares the applicability of （tricone bit） roller cone bits, PDC bits, and DTH hammer bits for this challenging formation.
Soaring Alloy Raw Material Prices: Impact on PDC and Tooling Production
This article analyzes the rapid rise in alloy raw material costs in 2024-2025, focusing on the mounting pressure on downstream manufacturers of PDC cutters, PDC bits, and alloy tools, while exploring future price trends.
Which Gage Protection Is Right for Your Drill Bit?
This article explores the critical choice between Tungsten Carbide pads and PDC cutters for bit gage protection. It breaks down their working principles, pros, cons, and provides a clear selection guide based on formation abrasiveness and drilling objectives to optimize performance and longevity.
What is the Center Column on a Mining Concave PDC Bit?
The center column is a fundamental design feature of mining concave PDC bits. These columns, protruding upwards within the bit's concave profile and armed with PDC cutters, are critical for enhancing stability, improving cuttings removal, increasing rock-breaking efficiency, and extending the bit's lifespan in challenging formations.

Battling PDC Bit Balling: Prevention and High-Efficiency Solutions
Bit balling in PDC drilling cuts ROP by 40–70%, induces well-control risks, and accelerates cutter wear. Key fixes: inhibitive drilling fluids (low-solids, KCl-enhanced), hydraulic optimization (flow rates >1.0 m/s annular velocity), and structured bit designs.
