What are carbide burs used for?

Carbide rotary burrs, also known as rotary files or die grinder bits, are used for shaping, grinding, and removing burrs, burs, and sharp edges from materials. The most frequent uses of carbide burs are to excavate and prepare cavities, finish cavity walls, complete restoration surfaces, drill old fillings, finish crown preparations, shape bone, remove impacted teeth, and separate crowns and bridges. Their heads and shanks identify burs made of carbide. Which kind of shank is required depends on the sort of workpiece being utilized. The sort of cutting design or head shape used depends on the process to be carried out.

Types of tungsten carbide rotary burrs

There are many types of tungsten carbide rotary burrs. 

According to the number of flutes it has, tungsten carbide rotary burrs can be divided into single-cut carbide burrs, double-cut carbide burrs, and diamond carbide burrs. Single-cut carbide burrs have a right-handed spiral flute. These tend to be used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly. Use for heavy stock removal, milling, deburring, and cleaning. Double-cut carbide burrs tend to be used on ferrous and nonferrous metals, aluminum, and soft steel, and also for all non-metal materials such as plastics and wood. They have more cutting edges and will remove material faster, leaving a smoother finish than a single cut due to producing smaller chips as they cut away the material. These are the most popular cut and will see you through most applications.

According to the shape of the tungsten carbide rotary burrs, there are tungsten carbide ball burrs, tungsten carbide tree burrs, tungsten carbide inverted cone burrs, tungsten carbide pointed cone burrs, tungsten carbide round nose burrs, tungsten carbide cylinder burrs, tungsten carbide oval burrs, tungsten carbide flame burrs, tungsten carbide oblate spheroid burrs, and so on.

Application of tungsten carbide rotary burrs

Tungsten carbide rotary burrs can be used to cut different materials, including steel, aluminum, cast iron, wood, acrylics, fiberglass, plastics, gold, platinum, silver, carbon steel, stainless steel, aluminum, cobalt, nickel, ceramics, carbon fiber reinforced plastic, glass fiber reinforced plastic, brass, copper, bronze, zinc, and so on. Tungsten carbide rotary burrs can be used for clipping the impeller runners, processing pipes, polishing the surface of inner holes, and routing and groove processing of various mechanical parts. They can also be used to finish machining the chambers of metal molds, such as shoe molds.
