Diamond bur & Tungsten steel bur

Diamond bur

Diamond has high hardness and excellent physical and chemical properties. Adhering or electroplating the diamond grains with a certain acute angle, according to a certain direction and spacing, with the central axis of the stainless steel bur as the center, to make a diamond bur with a certain ability to cut hard tissue.

According to different coatings, there are pure nickel coating, nickel-chromium coating, nickel-chromium-manganese coating.

According to the density of sand plating on the surface, it can be divided into two-layer sand-coated burs, three-layer sand-coated burs, full-sand grinding heads, etc., and the thickness ranges from a few microns to tens of microns. The increase in coating thickness can prolong the service life of the bur, improve the cutting rate, and be more environmentally friendly and cleaner.

Tungsten steel bur

It is formed by vacuum high-temperature sintering or high-pressure molding tungsten carbide powder and cobalt powder welded on a steel rod, and is processed and trimmed by a large diamond grinding wheel.

The resulting smooth surface of the tooth preparation allows for more precise impressions, resulting in more precise and tightly-margined all-ceramic restorations. Tungsten steel burs meet the requirements for minimally invasive tooth preparation.

The leveling performance of tungsten steel burs is good, and it is very suitable for the fine preparation of teeth, such as preparing grooves, barrel holes, dovetails, etc.
