How to use the carbide burrs

1. Speed /RPM

The speed at which you use your carbide bur in your rotary tool will depend on the material you're using it on and the contour being produced but it's safe to say you do not need to exceed speeds of 35,000 RPM. The table below shows some approximate speeds.
Diameter of Burr RPM
2.35mm or 3/32" 17,000 - 26,000
3mm or 1/8" 17,000 - 26,000
6mm or 1/4" 11,000 - 16,500
12mm or 1/2" 8,000 - 12,000
16mm or 5/8" 7,650 - 11,500
2. Apply only a little pressure
As with all drill bits and burrs, let the burr do the work and apply only a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too quickly, reducing the life of your burr.
3. Keep The Carbide Burr On The Move
When using your carbide burr try not to keep it still for too long as this will prevent the burr from digging and jabbing into your material causing unsightly marks and roughness.

Advantage of our carbide burrs

Product Application

Tungsten carbide burr is used widely in the shipping construction, auto engine porting and foundry fabrication. With its high rotating speed and hardness, it can machine a lot of different materials like cast iron, carbon steel, alloy steel and non ferrous material. High life service of product is warranted for virgin and excellent raw material which is one of most critical factors to the tools' life.

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.
