Let’s move further to learn more about its specifications and applications.

What Is 3mm Carbide Burr?

By 3mm carbide burr we mean, a rotary burr having a shank with 3mm diameter. It is the portion that gets fixed into the collet of the machine.

Carbide burrs are the small, high-speed rotary tools that are used for countless operations. For instance, grinding, cutting, milling, sanding, cleaning, and deburring.

These burrs are also known as small, miniature, or tiny carbide burrs. Due to the small diameter, the length of the shank is also not very long.

And similarly, a small flute is brazed at the shank head. So, all in all, these are the small-sized burrs suitable for smaller applications.

For example, if you want to carve delicate patterns on wood, these miniature burrs may help you bring out the minute details.

Syndent manufactures these small rotary burrs with high-quality tungsten carbide. You may get small carbide burrs in variable sizes and shapes.

Fixing the Burr into the Machine

From a wide range of shapes and sizes, choose the burr that you need according to your workpiece. Make sure your rotary machine is compatible with Syndent 3mm carbide burr.

If it is not, you may add a separate adapter to fix the burr into the collet. You can conveniently use air-powered, electric-powered, or battery-oriented machines.

Before fixing the burr into the collet, ensure the power supply is off. After screwing it tightly, plug in your machine.

Start Grinding

Switch on your machine. Put the rotating burr slightly on the surface of your workpiece. The sharp cuts of the flute will remove small burs. You don’t need to insert force on the burr to cut metal.

Secondly, for a better and controlled operation, Syndent suggests you move along the rotation of the burr. It prevents the vibrating and jumping effect of the burr.

Another critical factor that you must not oversee is the continuous movement of the burr. Keep rubbing your burr on the workpiece. Grinding on an exact place for longer may cause uneven and unwanted lines.


While working with Syndent fast speed rotating 3mm carbide burr, you must take preventive measures.

These measures include your safety and taking care of the surroundings.

Personal Safety

For personal safety, you need to have PPE.

What is PPE?

PPE stands for Personal Protective Equipment. It includes:

  • Hard hats
  • Safety shoes
  • Earplugs
  • Gloves
  • Eye protection
  • Face shield

Make your surroundings adequate for working. For this, make sure that:

  • The place is free from oil and liquids
  • The workpiece is tightly clamped to the bench
  • Your 3mm carbide burr is tightly screwed in the collet
  • Power supply connections are secured
  • There is no flammable object in the workshop

How Do You Clean Small Carbide Burrs?

Syndent manufactures small carbide burrs with the best raw material. Syndent uses K25 and K26 material to make sharp flutes. This material makes the flutes rustproof.

So, when it comes to de-clog your burr from aluminum deposits, you can conveniently use acid or caustic soda.

Acid doesn’t damage the burr. Instead, it removes the excessive aluminum of the burr.

There is another way to remove aluminum from the small carbide burr. It is the heating procedure. With heat, the aluminum will melt, and you can use a stiff wire for scratching clogged metal from the flute cuts.

Cylinder Head

Syndent manufactures three types of cylinder-shaped 3mm carbide burrs. These are:

  • Cylinder with flat end
  • Cylinder with an end cut
  • Cylinder with a radius end

The purpose of each type is different. A flat end is suitable for places that do not have a perpendicular side. Cylinder-shaped burrs with a radius end are ideal for flat surfaces with a curved corner.

Similarly, if a flat surface has a right-angled corner and you must grind both surfaces simultaneously, you may choose a cylindrical miniature carbide burr with an end cut.

How Is 3mm Carbide Burr Beneficial in Industrial Use?

In the industrial sector, 3mm carbide burr upholds specific importance. Big grinding wheels and powerful rotary tools are ideal for grinding more significant areas.

You cannot grind small, narrow, and deep areas with grinding wheels. For this reason, stick-like rotary files play a vital role in industrial sectors.

For example, if you need to maintain an installed machine, it is nearly impossible for you to uninstall and open it. You have to replace or maintain the component while intact.

In such situations, workers can grind smaller areas like a bearing, screws, bolts, or other machine components with Syndent rotary files.

Syndent manufactures unique long shank carbide burrs. These burrs can reach areas where standard length burrs cannot get.

So, in the industries, whether you are manufacturing or maintaining machines, a 3mm carbide burr helps you grind smaller areas.

Can I Use Miniature Carbide Burrs for Creative Applications?

Yes, of course!

Miniature carbide burrs are not specified with technical sectors only. You can make sculptures, carve wood, engrave glass or stone, and make patterns on ceramics with small rotary bits.

Some jewelry makers also use rotary bits for creating minute details in the jewelry. Variety in sizes and shapes makes it convenient for you to work on variable surfaces.

So, get your burrs and enjoy creating imaginative designs on wood and glass.

How Is Small Carbide Burr Different Than Long Shank Rotary Files?

The significant difference is the size. A carbide burr with a smaller shank diameter has a shorter length. At the same time, long shank burrs possess a comparatively bigger diameter.

For example, the length of a miniature burr is up to 75mm. At the same time, it is up to 83mm in a burr having a 6mm shank diameter.

Similarly, the flute length is more significant in longer shanks with greater diameters. The rotational speed of the burr also varies due to its size.

More giant flutes work better at a slower speed, and smaller burrs work at a faster rotational speed. So, with size, the rate also differs. However, you may get extraordinary lengths (on demand).
