What Is the Manufacturing Process of Air Grinder Bits?

The manufacturing process of your carbide burr consists of several steps.

Syndent’s expert team of engineers undertakes each step under their supervision. Let’s find out a step-by-step understanding of your air grinder bit’s manufacturing process.

Raw Material

Syndent uses high-quality cobalt – tungsten carbide for making the best rotary carbide bits.

We get all the raw material from trusted state-owned agencies. The raw material is inspected thoroughly to ensure it meets Syndent’s required specifications.

After a thorough check-up, the production process starts.

Air Grinder Bits


It is a process in which two metals are joined together. It is done by welding the flute with the shaft and filling the material in the joint.

Syndent uses silver as a brazing material. Silver is brazed into the joint automatically at a low temperature.


After brazing, Syndent conducts a jump test on all the air grinder bits. It ensures that your air die grinder bit possesses a tolerance level of less than 0.05mm.


In this step, Syndent tests the hardness and durability of the carbide burr. Our trained technicians bend the air grinder bit to a certain extent to examine its strength.


Here comes the time when your air die grinder bit attains its shape. With the help of grinding, a predetermined shape is acquired.


After grinding the flute into the required shape, it is further ground to form the sharp flute teeth.

The flute teeth are shaped and sharpened according to the predetermined cuts.


The air grinder bit then passes through a finishing process. It includes polishing of the shank. An abrasive material is used to polish the shank and giving it a smooth finished look.


It is the final step. It includes logo making. You can get your logos on the air grinder bit as well as on the plastic casing.

Plastic cases with an air die grinder bits packed inside, and logos stick on them are now ready for shipment.

Air Grinder Bits


An ideal air die grinder bit must be lightweight. You need to maintain the pressure on your rotary tool to attain the best results.

How to Use an Air Die Grinder Bit?

While using your air die grinder bit, you must take care of the following points:

  • Choose an appropriate flute cut and size you need for grinding the specific area.
  • Make sure your workshop is clean and free from any flammable object.
  • Tightly clamp your workpiece.
  • You must tightly screw your air grinder bit into the collet.
  • Loose air die grinder bit may cause damage to the burr and may harm you.
  • The air pressure from the air hose must not exceed 90psi.
  • Start your rotary tool first, and then place the carbide burr on the workpiece.
  • Take all the precautionary measures while working with your rotary tools.
  • Wear a face shield, gloves, air defenders, and glasses.
  • Avoid applying too much pressure. The pressure needed for each air grinder bit is mentioned in the manual guide Syndent supplies to you.
  • Do not grind on the same place for a longer time. Keep your rotary burr moving. Grinding in one place for a longer period may cause unwanted lines on your workpiece.
  • Too much pressure can cause damage to the flute teeth.
  • Do not touch your air die grinder bit immediately after use. It would be very hot and might hurt you.
  • Clean your air die grinder bit thoroughly after each use.
  • Don’t forget to unplug the power supply once you are done with grinding.

Does Metal Clog on Air Grinder Bits?

Excessive machining can cause metal clogging on your air grinder bit’s flute. Cleaning your rotary burr after each use can minimize the clogging. However, if you examine metal logged in your carbide burr, do not worry.

Here are few solutions for clogged flutes:

  • Dip your rotary carbide burr in acid (HCL). The acid will react with the metal and will clean your air grinder bit.

Your rotary bit will remain safe as Syndent makes it with special K25 material that will not react with acid.

  • You can dip your air die grinder bit in caustic soda. It will also help you to remove the clogged material from your flute.
  • Another ideal way to de-clog your air grinder bit is to use it on soft cast iron. Machine your bit in the soft iron will de-clog the flute easily.

Air Grinder Bits

What Is the Difference Between Tungsten Carbide Air Grinder Bit and HSS Burr?

HSS stands for High Strength Steel. The difference between tungsten carbide rotary burrs and HSS burrs are as follows:

  • Cobalt – tungsten with carbon compounds are used as raw material for making tungsten air die grinder bits. On the contrary, high-strength steel is used to make HSS burrs.
  • Tungsten carbide air grinder bit possess a high-speed. It works on 4 – 7 times faster cutting speed than an HSS burr.
  • Tungsten is a naturally strong material. Therefore the life span of an air die grinder bit made from tungsten carbide is longer than HSS rotary burr.
  • Tungsten carbide burr is comparatively expensive than an HSS burr.
  • Tungsten carbide air die grinder bit can resist harsh weather conditions. On the other hand, an HSS burr may lose its original shape in extremely hot conditions.
  • HSS burrs are brittle as compared to ductile carbide air grinder bits.
