What Is a Burr File?

Burr file is a high-speed rotary tool used to grind and mill various materials. These small files turn around at an excessive pace.

Syndent is known to use cobalt–tungsten carbide to manufacture high-grade burr files. The strong tungsten carbide permits them to perform at higher speeds as compared to HSS cutters.

You can divide the burr files into two significant parts – shaft and flute. Shaft is the straight long part of the burr that you fix tightly in the collet.

You can conveniently fix the collet with numerous rotary tools.

The second part is the sharp flute. The cuts and shapes of flutes are available in numerous styles. Syndent uses a specific K25 material to manufacture flutes of the burr file.

This material prevents your burr from corrosion and you can work for longer with strong and sharp flute teeth.

The 5s Management Solution

Here is the elaboration of what we mean by 5s management solution:

1.      Accumulating Raw Material

Syndent gathers raw tungsten carbide from the country’s best cobalt providers to manufacture burr files. The production system does not begin till and unless Syndent’s best manage crew approves the raw material provided.

2.      Brazing Method

The engineers use silver to braze the raw shafts and flutes. Different ways are used to join two metal pieces like welding, soldering, and brazing.

Syndent chooses brazing because it gives strength to the burr file and leaves no joint marks behind.

3.      Balancing and Bending Test

Once the brazing process is complete and the burr gets its primary shape, engineers test its balance.

Checking the balance, thoroughly, results in smooth rotation of the burr file while grinding. The balancing test is followed by the bending test.

The burr is bent to a certain extent to ensure that it will tolerate the vibrations and push back actions while working on hard metals.

4.      Cutting

At this level, the flute receives its shape and cuts. In the CNC machines, the flutes are processed thoroughly to obtain sharp predetermined teeth cuts.

5.      Polishing and Packaging

How to Use a Burr File?

Here are specific tips you can follow to attain better grinding results:

Do No Longer Practice of an Excessive Amount of Pressure

As with any drill bits and burrs, pressure plays an important role. It is not the pressure that gives you a smooth finish rather the sharp teeth that chip away excessive material.

Putting unnecessary pressure on the grinding burr file will cause uneven lines on your workpiece. Or, it can cause damage to the sharp teeth of the flute.

It is recommended to keep the pressure moderate. Also, keep it moving on the desired area, and achieve the required results.

Maintain the Carbide Burr at the Move

While using Syndent burr file, ensure that you keep the burr moving. It will help you to move along the grinding process neatly and evenly.

Moreover, to end up smoothly, Syndent recommends you to quit with an upward stroke.

Useful Note for De-clogging

Have you tried using your burr file on a forged iron?


Try it! It will leave your burr neat and new-like.

Selection of the Burr File

The main factor that determines your successful grinding is the selection of the burr file. For example, if you choose an inverted cone-shaped burr to grind a flat surface, it will not give you the desired results.

Similarly, while cleaning a hole, the size of the burr file matters a lot. Too small or too big burr may end up with a waste of time and energy.

So, be wise while selecting the burr bits. It is recommended to select a file almost half of the hole or even shorter when you need to grind a hole.
