If your process requires roughing or finishing functions in small or hard-to-reach areas, or your roughing abrasive has difficulty accessing closed angles and you are looking to speed up your roughing and finishing process, or you use molds and it is necessary to subject them to a process roughing; Then you can find the solution with tungsten carbide rotary files.


The tungsten carbide rotary burrs are highly recommended for the machining, roughing and finishing of small cavities which are difficult to access. This is due to its multiple cutting edges, which make it possible to achieve excellent levels of finish / surface quality, benefiting its use in a wide range of conditions.

In this post, we will be looking at the correct selection and use of the tungsten carbide rotary files as it applies to your business.

Let's get started!

The best choice in tungsten carbide rotary files

The correct selection of the cutting tool is based on the hardness of the material and the required finish.

However, there are different types of cut that can help you in your process, but our focus will be on how to select and apply the carbide rotary burr.

Now, what are the advantages of tungsten carbide rotary files in industry?

The tungsten carbide grades selected specifically for each rotary file model and its specialized design achieve high removal rates along with long life. When properly used, the tungsten carbide grade tools can have a tool life that are 50 to 100 times longer than the high-speed steel equivalent (HSS) file. In addition to such advantage, a tungsten carbide rotary burr will allow you to make heavier cuts with more aggressive feed rates and an exceptional surface finish.


The extreme hardness of tungsten carbide grades makes them ideal for use in a wide variety of applications, specifically in specialized industries such as automotive, aerospace, precision engineering and casting. In addition, rotary files can be used in foundry machines, fiberglass, plastics, ceramics, sand cores, and a wide range of other composite materials.

Hard materials welded, forged, or used within the mold and die industry, such as chrome, nickel, and cobalt steels can be mixed gently. And, hard materials such as high speed steel, ice iron, and stelite can be machined with precision and good tool durability using the rotary burr sets.


Tungsten carbide rotary burrs are produced and supplied in a wide range of standard and custom-made shapes and sizes. They are also available in long, double-ended or flexible versions to suit the most specialized processes and applications in a wide range of industrial applications.

Tungsten carbide rotary files can also be specially produced with flute size and cuts according to customer specifications.
