Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 7787 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 7787-2 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee
SC 4, Dental instruments.
This fourth edition cancels and replaces the third edition (ISO 7787-2:1998), which has been technically revised as
follows:
� addition of designation of toothing;
� addition of labelling and marking requirements;
� exclusion of miniature carbide laboratory cutters.
ISO 7787 consists of the following parts, under the general title Dental rotary instruments — Cutters:
� Part 1: Steel laboratory cutters
� Part 2: Carbide laboratory cutters
� Part 3: Carbide laboratory cutters for milling machines
� Part 4: Miniature carbide laboratory cutters

ISO 7787-2:2000(E)
Introduction
This part of ISO 7787 is one of a series of standards relating to dental rotary instruments.
The various dimensional and other requirements specified for carbide laboratory cutters are those considered
important to ensure the interchangeability and safe usage of these instruments in the dental laboratory.
The nominal diameters of the working part listed in Tables 1 to 11 comply with the diameters specified in ISO 2157,
Dental rotary instruments — Nominal diameters and designation code number.
Attention is drawn to ISO 6360, which specifies a 15-digit number coding system for the identification of dental
rotary instruments of all types.

Part 2:
Carbide laboratory cutters
1 Scope
This part of ISO 7787 specifies the dimensional and other characteristics for the 11 most common carbide cutters,
which are predominantly used in the dental laboratory.
NOTE Steel laboratory cutters are specified in ISO 7787-1; carbide laboratory cutters for milling machines are specified in
ISO 7787-3; miniature carbide laboratory cutters are specified in ISO 7787-4.
