Tungsten Carbide Rotary Burr Tool For Woodworking Tools Impact
Toughness
1.What Speed or RPM should you use your Carbide Burrs?
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.
If the burs are chipping easily this could be due to the speed
being too slow. However, it's ideal to start the bur off slow,
increasing the speed as you go along. High speeds will prevent
clogging in the flutes of your burs.
Diameter of Burr | RPM | |
1.6mm or 1/16" | 25,000 - 35,000 | |
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. Do Not Apply Too Much 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. Carbide Burrs are Harder Than HSS Burrs
Our Carbide Burrs are machine ground from a specially chosen grade
of carbide. Due to the extreme hardness of the Tungsten Carbide
they can be used on much more demanding jobs than HSS (High Speed
Steel).
Carbide Burrs also perform better at higher temperatures than HSS
so you can run them hotter, and for longer.
HSS burrs will start to soften at higher temperatures so carbide is
always a better choice for long term performance.
Company Profile
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.
