A variety of different types of burs are used for dental procedures and treatments, with a huge range of shapes and sizes to choose from. There is also a selection of materials, which includes carbide and diamond. Carbide burs are made of tungsten carbide, which is 3 times harder than steel and therefore more robust against breaking or chipping. These burs are primarily designed for cutting away hard tissue, such as bone and enamel. They are available with a friction grip shank or latch type RA shank.
Diamond burs are a more sophisticated alternative to carbide burs and they are used to cut more delicate materials such as ceramic, glass and tooth structure. They can be used in places where a metal or steel bur would damage the surface, such as when working on partial frameworks. These diamond burs are available with a variety of grits from ultra fine to super coarse, and come in a range of shapes.
There are a number of different ways that sintered diamond burs are manufactured, the most common is by combining a solid core with a layer of abrasive diamond. This allows for the diamond to be embedded in a matrix of solid material, which increases durability and performance. The benefit of using this method is that it provides a stronger, more stable bur while still allowing for the use of high-quality diamonds in an economical way.
These sintered diamond burs are perfect for gem carving and pre-forming glass, stones, ceramics, bone and metals. They have a rounded cone-shaped tip and feature a 1-1/2″ long steel mandrel shank that’s 3/32″ in diameter. The burs easily fit into a Foredom, Dremel with 3/32″ collet, or any flex shaft hand piece that accepts 3/32″ diameter shanks. Simply lubricate with clean water before and during use.
Each Neosint sintered rounded cone diamond bur has a diamond head that is made with sintered technology. The diamond is embedded into a metal matrix throughout the entire head of the bur to provide longevity and consistent cutting quality. This is a great alternative to electroplated burs and will outlast them by at least five times when used correctly.
