Tungsten carbide rotary burr is one of the small carbide tools used in different industries such as machinery, automobiles, ships, chemicals, craft carving, etc. You can use it for different applications, but usually used for de-burring, just like its name.

If you are a beginner to use tungsten carbide rotary burrs, you may have these following 3 questions:

1. How to choose right shape and size of carbide rotary burrs?

2. How to fit carbide rotary burrs?

3. When using carbide rotary burrs, what should I pay attention to?

Here KoneTool prepared 7 best useful tips for beginners, which can make your tungsten carbide rotary burr has an incredible efficiency and life.

 

1. Shape----choose right shape for your specific project.

If you are a DIY lover, you probably will buy a tungsten carbide rotary burr set to fit different applications. A burr set usually have 5, 8, or 10 different shapes of burrs. But in a specific work, do you know how to choose? Here is our guide:

2. Size---choose a bigger head

Bigger carbide head has higher efficiency. So, choose a reasonable big head can speed up work and save your time.

3. Fitting---choose right chuck

At first, please use correct chuck for corresponding burrs, and check concentricity of machine to avoid tremor and shock. Otherwise, it will cause premature wear.

Secondly, for safety, grabbing position should be at least 2/3 of shank. Please avoid grabbing too short.

 

4. Direction---avoid reciprocating movement


During de-burring, please move burr head in one direction(like left to right, or right to left). If you move it back and forth, it may cause premature wear and crack of cutting edge.

5. Grease---use grease for highly viscous materials

When processing highly viscous materials, you’d better use lubricating oil or grease, to avoid carbide burr doesn't work, due to blockage of chip removal groove.

 

6. Pressure---use a suitable pressure


Using a suitable pressure during working. Much high pressure will cause temperature is too high to dissipate. It may even cause welding part to fall off.

7. Speed---Choose maximum RPM within allowable range.

No matter what tools you use, RPM always cares. For tungsten carbide rotary burrs,  reasonable operating speed is very important to achieve required degree of cutting and workpiece quality.

Try to choose highest speed within allowable range. minimum RPM should be above 3000. Because low speed will reduce chip removal performance and produce trembling, which results in reduced tool life and poor surface finish.

Each type of rotary carbide burr must select appropriate operating speed according to specific application. Knowing 2 following methods, you can try to adjust speed to a suitable number.

 

Increasing speed can improve processing quality and lengthen tool life, but it may cause shank to break;

Reducing speed will help to quickly remove material, but may cause system to overheat and cutting quality to fluctuate.

After reading this article, I hope you have a basic understanding of carbide rotary burr and can solve 3 problems at beginning.
