The base and material for the shank production is stainless steel
with nickel protective and decorative coating that provide
the necessary corrosion resistance of the product. Additional
spraying of titanium nitride or double nitride titanium aluminum
improves the technical characteristics of burs and increases tool
life. Diamond layer of heads is composed of diamond powder and
metal binder of galvanic nickel.
Burs with diamond heads RosBel are produced of different forms
and sizes of shank and working part and granularity of diamond
powder. According to shank construction burs are classify to
types:
for fixing in angle tips;
for fixing in straight tips;
for fixing in turbine tips.
The main working characteristic of bur is its granularity. Dental
diamond burs are produced of 6 types depending on the size of the
diamond grains. Each type corresponds to a special numeral and
color codes which are marked on the tool or on the packing.
Coding conforms to generally accepted international standards.
