Fitting Bur is generally used for reducing tooth structures to place crowns or porcelain veneers. Diamonds may also be used to smooth, refine, and polish composite or porcelain. material. Diamond is the hardest of all known materials. Fitting Bur is most commonly used with high-speed handpieces, meaning they are most commonly available as a friction grip shank. This is the hardest material available and is used to grind away tooth tissue, usually enamel. The grinding motion of a diamond bur leaves a rough finish. A burr is the part of some plants which contains seeds and which has little hooks on the outside so that it sticks to clothes or fur.

Fitting Burs are used for cutting, shaping, grinding and for the removal of sharp edges, burrs and excess material and this is what we talk about in the following article. Burrs are small fluffy fibres that are separated from the hair. These fibres are again scored and dried. The wool obtained is now ready to be drawn into fibres. The burrs function as hooks to attach the seed pod or plant part to a moving host. As the host continues on its way, the burr hangs on until the host deliberately removes the burr or accidentally brushes against a surface that dislodges it.
