Description of Carbide Composite Rods:

Tungsten carbide composite rods, specifically designed for safeguarding high-wear components in the oil and gas drilling, geothermal, mining, and geological exploration industries, cater to a range of critical equipment such as washover shoes, stabilizers, down-the-hole drill bits, reamers, drill rods & subs, and more.

KINGTOOLS proudly manufactures high-caliber tungsten carbide welding rods, meticulously crafted from sintered tungsten carbide particles and a high-tensile alloy. The welding rod substrate is meticulously selected from copper or nickel, with the coating serving both a functional and identifying role. The application of the tungsten carbide welding electrode is executed through the oxyacetylene brazing method.

For precision cutting applications, tungsten carbide hardfacing welding rods featuring larger particles are recommended, while smaller particles are preferred for applications requiring enhanced wear resistance.

Advantages of Carbide Composite Rods:

First, to increase the speed ofdownhole milling and cutting.

Second to protect the surface of tools subject, to abrasive wear,maintaining full guage on stabiliz-ers, guides keyseat wipers, andother downhole tools.

• High Strength
• High Hardness
• Abrasion Resistance
• Long Service Life
• Easy to Replace

Applications of Carbide Composite Rods:

Carbide compositerod has wear andcutting properties coupled by high-endweldability and low fuming, allowingthe material to use in stabilizersreamers, drill pipe joints, constructiondrilling, hydraulic-cutter, twist drill,etc.

Joint carbide co.,ltd was established on January 21, 2019, as a sales branch established by Zigong joint carbide co.,ltd in Chengdu.Our company covers 20,000 square meters was a high-tech enterprise integrating research, development, production and sales of cemented carbide products and cemented carbide rotary burrs，carbide tire studs，carbide repair tire stud，carbide particles & composite welding rods.

The company is committed to providing high-precision, high-speed and efficient metal grinding solutions and services for the machinery manufacturing industry. The company introduced the most advanced international five-axis five-linkage CNC tool grinder, three-coordinate tool detector and other equipment from Germany. The aim is to produce high-quality, internationally competitive products using internationally advanced equipment. At present, our company has become the largest rotary file production base in the country, with a mature R&D team and management team in China, and a stable supply chain.

As a metal cutting tool, the rotary file has been exported to Europe, North America, South America and a small number of Southeast Asian countries.A few days ago, the company has completed the accumulation of various infrastructure and technology research and development. Since 2020, our company has added 200 five-axis and five-linkage rotary grinders. By 2023, our company will invest a total of 400 five-axis and five-linkage rotary grinders. Grinding machine (total value 150 million yuan). By then, our company will become the world's largest supply base for rotary files.We have the world's advanced raw material cemented carbide formula technology, the most optimized advanced manufacturing process, and the largest-scale production equipment.
