In modern heavy-duty geotechnical operations—including asphalt pavement milling, deep foundation rotary drilling, underground coal mining, and tunneling—cutting picks operate under some of the most punishing tribological conditions in industry.A standard conical cutting tool (also known as a bullet bit, milling pick, or cutter tooth) consists of two primary metallurgical components:The Carbide Insert (Tip): Typically composed of Cobalt-bonded Tungsten Carbide (WC-Co), engineered for extreme hardness and rock-breaking capacity.The Tool Body (Shank): Forged from high-strength alloy steel (such as 42CrMo or equivalent), designed to absorb intense mechanical shock and transfer torque from the machine drum.While the tungsten carbide insert is built to withstand penetration forces, the underlying alloy steel body is significantly softer and inherently vulnerable to severe abrasion from high-velocity rock dust, sand, and asphalt aggregate. This vulnerability leads to a primary indust
From early 2025 to the first quarter of 2026, the global tungsten market experienced an unprecedented price surge. The price of black tungsten concentrate broke the one-million-yuan mark, and high-purity tungsten powder soared to 2,100 RMB/kg, both surging by over 600%. As the "backbone" of cutting
