Grinding Burrs – The Ultimate FAQ Guide

Chipping out rough metal edges has never been an easy task. Grinding burr is a must-have in your toolbox when it comes to metal grinding.

Read more to get the answers to your entire how’s, what’s, and if’s. This article contains direct knowledge about a grinding burr.

So, let’s get started!

What Are Grinding Burrs?

Grinding burrs are also known as grinding files or grinding bits. These are small-sized rotatory tools. A small shaft with a sharp flute head is all a grinding burr contains.

You can attach your rotary tool to different types of machines. However, the most suitable and commonly used device is the die grinder.

These small tools are simple, sharp, durable, and efficient.


They can cut variable materials into small chunks. Whether working on metal surfaces or plastic, concrete or glass, carbide grinding burr removes unwanted material quickly.

Why did I mention carbide here?

The reason is that Syndent manufactures its high-grade rotary tools with the world’s most rigid material, tungsten carbide.

Tungsten carbide makes grinding burrs strong, balanced, durable, heat-resistant, and wear-resistant.

Now that you know burr’s structure, let’s learn more about the various types and shapes available.

How to Use Burr Grinder Together with Grinding Burrs?

Variable shank diameters allow you to use grinding burrs with multiple machines. However, a die grinder (air-powered or electric-powered) is the best rotary machine for tungsten carbide rotary tools.

Things to Consider

  • Always remember, your safety is the first thing to keep under consideration. For this reason, fix the burr into the collet before plugging in the power supply.
  • Clean the surroundings. Ensure there is no flammable material nearby.
  • You must fix the grinding burr tightly into the collet. Use a wrench for this purpose.
  • On the working bench, tightly fix the workpiece.
  • Working speed is mentioned in the guidebook of the die grinder. You must read the manual guide carefully as the rate varies with sizes and working materials.
  • After securing the workpiece, cleaning the surroundings, and fixing the burr, it is time to plug in the machine.
  • Start the grinder first. After that, place the rotating bit on the desired area.
  • With slight pressure, keep wiping the burr on the workpiece.
  • It is recommended that you keep your burr moving. Otherwise, it will remove more material than desired.
  • Working at a low speed may result in a clogged burr. Working at high speed may cause vibration and kick-back actions. Therefore, always work at the recommended rate.
  • When the burr gets cold, remove it, clean it, and store it in your toolbox.

Can a Metal Grinding Burr Cut Wood?

You can conveniently work on multiple surfaces with your metal grinding burr. One of these materials is wood.

If you are linked to the wooden industry, wood grinding burrs are a must-have for you. You can carve beautiful patterns and make sculptures with the help of these files.

The various cuts and shapes allow you to work on narrow and deep places, sharp edges, and angled corners.

The sharp flute cuts remove the wood chunks quickly leaving the wooden log smooth and reshaped.

What Is a Grinding Burr Set?

A grinding burr set is a kit that contains various rotary files. These sets are available in different combinations.

For example, you may get 3, 4, 8, or 9 burrs in a kit. Standard sets that Syndent produces contain small burrs, double-cut burrs, and long shank burrs. However, you may get (on demand) customized sizes, shapes, and numbers of files in your grinding burr set.

How Can I Clean a Grinding Burr for Aluminum?

Cleaning a grinding burr is not a problematic task – thanks to the K25/26 material Syndent utilizes. The anti-corrosive tungsten carbide, along with K25 material, allows you to clean your burr conveniently.

You can use caustic soda or acid to remove the clogged aluminum from the flute cuts. Dip the burr into the soda or HCL. Leave it for some time.

Ensure that only the flute is in the acid. Shank is not resistant to acid.

After some time, rub the flute with a stiff brush. Repeat the procedure if there is still some aluminum left in the cuts.

You can also use the heat to remove clogged aluminum. Heat will melt the aluminum, and you can remove the chunks by using a hard-wired brush.

What Is the Difference between Burr Grinding Wheel and Carbide Burrs?

Burr grinding wheel is a circular disc that has abrasive grits on the surface. These abrasive grits grind the metal/wood surface.

Grinding wheels are available in variable sizes, grits, and abrasives. You can choose the best-suited wheel according to the material you are working on.

At the same time, carbide grinding burrs are small stick-like tools that have sharp flutes at one end.

Burr grinding wheels are also available in steel discs. These discs do not have abrasives, rather they have small sharp cuts on the surface that allow you to grind and cut unwanted material.

These flutes are available in different sizes and shapes. You can choose the shape, cut, and size according to your workpiece.

The difference between the two is in their material and also the way they work. Grinding wheels cover a larger area with a plain surface. Working on corners with the grinding wheel is comparatively rigid.

On the other hand, rotary burrs can conveniently work on edges, angled corners, curved corners, or small areas.

You can enlarge holes with a grinding burr, but a grinding wheel can only work on flat surfaces.

What Is the Difference Between HSS Rotary Burr and Carbide Grinding Burr?

The main difference between the two is in their raw material. HSS means High-Speed Steel. These burrs are made with steel. On the other hand, carbide grinding burrs are made up of tungsten carbide.

Besides the raw materials, there are some other common differences. These are:

  • HSS rotary burr is not resistant to heat. Tungsten carbide grinding burrs are heat resistant. You can work for an extended period, and its sharp flute cuts will not lose their shape or sharpness.
  • Tungsten carbide files have a longer life span than HSS rotary burrs.
  • Talking about the cost, HSS burrs are comparatively cheaper than tungsten carbide ones.
  • Tungsten carbide is more challenging than steel. Therefore, the wear resistance is more in carbide burrs than in HSS burrs.

What Is the Use of a Diamond Grinding Burr?

Diamond grinding burrs are most commonly used in the dental industry. They are utilized in the placement of veneers and crowns.

These burrs are made up of stainless steel with diamond powder bonded, on the burr head, in variable grit sizes. You may choose the grit size and burr head size according to your need.

Diamond grinding burrs with various grit sizes allow you to cut faster. Similarly, finer grits leave the surface smooth and give a more polished look.

These two types are different in their functionality. The carbide burrs cut with the sharp small blade cuts on the flute, whereas, dental grinding burrs grind the tooth with the diamond grits.

After grinding the surface remains rough. You may polish it later for a smooth finish.
