the difference between tungsten carbide bur and diamond bur


The bur is a must-use thing in the clinical work of the stomatology department. The device designers have designed different types of burs according to the various needs of dental preparation. As we all know, choosing the appropriate bur can make the operator's work effective with half of the effort. At present, burs are divided into tungsten carbide bur and diamond bur. The following is the main difference between the two.


Tungsten Carbide Bur

The tungsten carbide bur consists of integral tungsten steel, without process problems. There will be no U-turn problem that the working end is broken, and it also has high concentricity, strong hardness, no rust, good wear resistance, and high-temperature resistance. 


Generally, a tungsten carbide bur can remove more than ten metal-ceramic crowns or metal-ceramic teeth. However, some tungsten carbide burs have low concentricity, and there will be tremors when drilling teeth, making the patient uncomfortable.

Diamond Bur

The diamond bur has a certain acute angle of emery grains, which are adhered or electroplated in a positive direction. There are many small diamond grains attached to the periphery of the diamond head drill bit.


These diamond grains are good at impurity removal, demagnetization, spheronization, purification, sharpness, and wear resistance. During the use process, the diamond grains are easy to fall off. Its life cycle is over when half of them falls. The diamond bur takes an hour to remove a metal-porcelain tooth or a porcelain crown and will damage 2-3 or more needles, so its work efficiency is lower than the tungsten carbide bur.


Therefore, when choosing a bur, the doctor tends to choose a tungsten carbide bur, because it is durable, stable, and sharp, but some of them will also use a diamond bur. So Which kind of bur will you like to use?
