Solid tungsten carbide stud cores are the raw material for tire stud assembly, offering high hardness and wear resistance with customizable diameters. Also known as tungsten carbide pins, these cores are the wear-resistant working components of tire studs. Made from sintered cemented tungsten carbide, they are embedded at the top of the stud body as the part that contacts ice and the road surface, delivering core anti-slip and wear performance.

• High Hardness: Ensures durability and longevity for heavy-duty tire studs.
• Tungsten Steel Studs: Provides superior penetration and gripping power.
• Carbide Tip: Enhances cutting efficiency and reduces wear during installation.
• Precision Design: Ideal for professional tire stud assembly applications.
• Easy Installation: Simplifies the process for efficient tire maintenance.

• Tire stud manufacturers and hardware processing factories
• Assembly production of various press-in and screw-in tire studs
• Replacement of worn carbide tips on used studs
• Production of other wear-resistant industrial pins

Chengdu Joint Carbide Co., Ltd. was established on January 21, 2019. Zigong Joint Carriage Co., Ltd. is the sales subsidiary of the group in Chengdu. We are a manufacturer of hard alloy cutting tools, established in 2007, covering an area of nearly 20,000 square meters. We are a high-tech enterprise integrating research and development, production, and sales (certificate number GR201951000516). We produce hard alloy cutting heads, rotary burrs, tungsten composite rods, hard alloy drill bits, hard alloy rods, rotary burr blanks, and other hard alloy products from China.

We have introduced more than 430 German five-axis five-linkage CNC tool grinders and three-coordinate optical tool detectors. Daily production can reach 25,000–30,000 pieces. We are the only rotary file enterprise in China that independently produces the entire process from raw materials to finished products. Today, our company has become the largest rotary file production base in the country, providing high-precision, high-speed, and efficient solutions for hard alloy products and metal polishing in the mechanical manufacturing industry.

We possess world-advanced raw material hard alloy formula technology, optimized advanced manufacturing processes, and the largest-scale production equipment.

• Our Mission: To provide the best overall polishing solution for the mechanical manufacturing industry.
• Our Vision: To become the world's largest production base for grinding and cutting tools.
