Do You Know About Milling Burs?

The milling bur is a rotary cutter with several teeth, and each tooth is comparable to a turning tool that is fixed to the rotary surface of the milling burs. The cutting edge that is actively cutting during milling is longer, there is no idle stroke, and the Vc is higher, all of which increase productivity. Milling cutters come in a variety of forms, with various structural variations and uses. They can be categorized into three groups based on their intended uses: milling cutters for processing planes, milling cutters for processing grooves, and milling cutters for processing forming surfaces.

Given that milling equipment and milling equipment play different roles in the production of dental materials, the choice of grinding and milling tools is crucial.In general, milling burs are broken down into cylindrical cutting tools, contact burs, end milling cutters, three-face milling burs, etc.

Milling bursts with a cylinder and an annulus

According to the tooth shape, the milling cutter's cutter teeth are distributed evenly around its circumference and classified as straight teeth or helical teeth. There are two different types of coarse teeth: those with fewer and those with more teeth. While the fine-toothed milling cutter is best for finishing, the coarse-toothed helical milling cutter is best for rough machining because it has few teeth, strong tooth strength, and a big chip space.

Contact period

On vertical milling machines, face milling machines, or gantry milling machines, it is used to machine planes. On the end face and circumference, there are cutter teeth as well as coarse and fine teeth. Integral type, insert type, and indexable type are the three types of its structure.


It is used, among other things, to process grooves and stepped surfaces. Because they are on the perimeter and end face, the cutter teeth cannot be fed in an axial direction while the machine is in operation. End mills with through-center end teeth enable axial feed.

Milling bursts with three faces

This kind contains teeth on the inside and exterior of the cutter and is used to create grooves and stepped surfaces.

Different coatings for various materials are used on milling burs. For instance, CrN, DC, and DLC.

Wax and zirconium can both be coated with the most popular type of coating, DLC.

Milling burs are small cutting tools used in dental and industrial applications for cutting, shaping, and carving materials such as metal, acrylic, and ceramic. They come in various shapes and sizes, including cylindrical, conical, spherical, and torus shapes. Milling burs may be made of different materials, such as diamond-coated tungsten carbide, zirconia, and ceramic, depending on the specific application. They attach to a milling machine or dental handpiece and are used in high-speed rotation to remove the material in precise and controlled increments. The quality of the milling bur can impact the accuracy and efficiency of dental restorations or industrial productions.
