Drills are core drilling tools in mining and oil & gas drilling fields, directly determining drilling efficiency, costs, and operational safety. Different geological conditions (such as soft formations, hard rock, and tight oil & gas formations) and drilling purposes (such as open-pit mining, deep ... Read More

Polycrystalline Diamond Compact (PDC) bits are high-efficiency drilling tools widely used in oil and gas drilling, mining, geological exploration, and other fields. As a key functional component, the nozzle undertakes core roles such as injecting drilling fluid, cooling PDC cutters, flushing ... Read More

As a core drilling tool in oil and gas drilling, mining, and other fields, the nozzle (also known as "water eye") of a roller cone bit is a key component—it is mainly responsible for injecting drilling fluid to achieve the core functions of cooling the bit, flushing cuttings, and protecting the ...

As a core material in the industrial processing field, cemented carbide’s ISO (International Organization for Standardization) classification standards provide a unified selection basis for practitioners worldwide. Centered on three core dimensions—"workpiece material compatibility", "performance ... Read More

In the industrial slitting field, high-speed steel slitting knives and carbide slitting knives are two mainstream options, each suitable for different slitting scenarios. Due to differences in material properties, performance, and cost positioning, they have their own advantages and disadvantages in ... Read More

Turning inserts and milling inserts (mainly made of tungsten carbide cemented carbide) can both be reground. Proper regrinding is a practical solution to reduce tool costs and improve resource utilization. For issues such as minor wear, edge dullness, and small-area chip adhesion during machining, ... Read More

End mills, especially those made of tungsten carbide cemented carbide, can be reground. In fact, proper regrinding is a key way to extend tool life and reduce production costs. For minor wear, edge dullness, and other issues that occur during machining, professional regrinding can restore their ... Read More

In the slitting process of materials such as adhesive tape, film, and label paper, cemented carbide slitting circular knives are prone to residual adhesives (e.g., hot-melt adhesive, pressure-sensitive adhesive) on the cutting edge and knife body surface. If not removed in time, these residues can ... Read More

In industrial slitting (e.g., paper, metal foil, film) and food processing (e.g., meat, pastries), circular knives are prone to cutting edge damage due to contact with hard objects (such as metal impurities, bones), improper operation (e.g., high-speed impact), or long-term use. Common damages ... Read More

In the food processing industry, the performance of circular knives for food cutting directly affects food quality (e.g., cut flatness, no adhesion), production efficiency (e.g., tool change frequency), and food safety (e.g., no leaching of harmful substances). Many practitioners wonder: Can ... Read More
