Indexable reamers are precision hole-finishing tools for metalworking, featuring replaceable carbide inserts (no regrinding needed) and modular designs. They deliver high accuracy, efficiency, and cost-effectiveness in mass production, replacing traditional solid reamers for medium-to-large batch machining. Our reamers are engineered with advanced insert clamping, internal coolant systems, and wear-resistant coatings to meet strict tolerance and surface finish requirements.

Cemented carbide mushroom-shaped ball tooth is named for its mushroom-like shape. It is an efficient crushing tool component made of cemented carbide material. The head is round and thick, with excellent impact resistance and wear resistance. It is mainly used in crushers, impact drills, roadheaders and other equipment. Suitable for crushing hard materials such as rocks, ores and concrete, it has high crushing efficiency and long service life.
Cemented carbide ball is a spherical cemented carbide product made by high-precision forming and sintering processes. It has extremely high hardness, wear resistance, corrosion resistance and dimensional accuracy. Widely used in bearings, valves, precision instruments, abrasive media and other fields, it can be used as rolling elements, seals, grinding media, etc., with the characteristics of long service life and stable operation.
Carbide Ball Teeth, also known as carbide ball inserts, tungsten carbide ball teeth, or conical picks, are a specific type of wear part and cutting tool characterized by their hemispherical (ball-shaped) head made of tungsten carbide. They are primarily designed for robust impact, crushing, and grinding applications, rather than precise shearing or slicing. Their unique design allows them to transmit high point load forces into the material, making them ideal for breaking extremely hard and abrasive substances.
V-CUT knives (also known as V-shaped cutting knives or V-groove knives) are specialized tools for PCB (Printed Circuit Board) processing, metal sheet grooving, and V-groove machining of materials such as acrylic and plastic. Below is a detailed description from the perspectives of core characteristics, classification, parameters, and applications:
Square CNC turning inserts are one of the commonly used cutting tools in CNC turning processes.
This machine tool is a special-purpose machine tool for machining cylindrical deep-hole parts. It is suitable for drilling and boring cylindrical deep-hole workpieces. During boring, an oil feeder is used to supply oil, and the chips are discharged to the chip hopper at the head of the machine through the cutting zone. During drilling, an internal chip removal method (BTA) is used, that is, an oil feeder supplies oil, and the chips are discharged from the inside of the drill rod to the chip hopper at the rear of the machine through the cutting zone.
The cemented carbide wear-resistant bushing dedicated to the geology and mining field is made of cemented carbide material with high cobalt content and high hardness.
