6mmTungsten Carbide Rotary Files Power Tools Tungsten Carbide Drill Bits

A Burr (sometimes called rotary files) are small cutters used in die grinders, rotary tools or dentist's drills. The name may be considered appropriate when their small-sized head (3 mm diameter shaft) is compared to that of a seed of the burr fruit or the teeth compared to a metal burr. To maintain the correct surface speed and cutting conditions they are rotated at the highest speed possible, commensurate with their size and construction. The cutters shown in the image are made from tungsten carbide, which allows them to run at higher speeds than similar HSS cutters, yet still maintain their cutting edges. Burrs (the tools) are also used in CNC machining centers for removing burrs (the small flakes of metal) after a machining process. These tools usually spin at several thousand RPM. Because the cutting edges are so small, they can be touched when spinning by a finger without cutting the skin, which flexes out of the way, although it would not be safe to pinch or grip them from two s ides. Hard metal or ceramic workpieces cannot flex beyond the cutting edges, so the tools remove material from them. This characteristic makes them suitable for dentistry, as the tool will grind the hard enamel of teeth, yet leaves soft mouth tissues unharmed if the tool should erroneously touch them.

We offer a wide assortment of carbide burrs as part of the Dormer rotary tooling program. Our range covers a variety of applications and materials, including hardened steel, non-ferrous materials and plastics.

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.
