This part of ISO 3823 specifies dimensions of, and require-ments for, the twelve most commonly used forms of steel and carbide finishing burs. It is envisaged to extend the scope of this International Standard to cover other forms of burs.
Other characteristics of bur heads, for example spiralled blades, cross-cut, are not covered by this International Standard. These will be dealt with in a future International Standard.
