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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 6360-3 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 4, Dental

Introduction
This part of ISO 6360 is one of a series of International Standards relating to dental rotary instruments. A wide
variety of dental rotary instruments, including root-canal instruments, is manufactured throughout the world for
use by the dental profession.
ISO 6360 provides a general number coding system for all types of dental rotary instruments, including
accessories used in connection with these rotary instruments.
The benefits of this system for dentistry in its entirety will only be derived if the system is widely adopted;
manufacturers of dental instruments, as well as the dental trade, are therefore requested to refer to ISO 6360
in their catalogues.
This part of ISO 6360 was prepared in response to a need by the dental trade and industry and the dental
profession for a universal system of classification and designation for these instruments. It establishes a
comprehensive number coding system suitable for all dental rotary instruments by use of a 15-digit code
number identifying general and specific characteristics of instruments or groups of instruments.
The first group of three digits identifies the materials used for the working part of instruments.
The second group of three digits identifies the shanks and handles used for instruments and the overall
lengths of instruments.
The third group of three digits identifies the shapes of instruments.
The fourth group of three digits identifies the specific characteristics for groups of instruments.
The fifth group of three digits identifies the nominal diameter of the working part of the instruments.
The code numbers are generic code numbers. They do not provide exact product information. This
information is given in the respective product standards for dental rotary instruments.
For the application of the system and for the correct allocation of numbers or their identification it is intended
that the user consult ISO 6360-1 and ISO 6360-2 for general information, and in addition one of the
subsequent parts (ISO 6360-3 to ISO 6360-7) for further information on specific characteristics of instruments
or groups of instruments.
For the allocation of new numbers complying with ISO 6360, an application supported by a description and a
drawing should be sent to the secretariat of ISO/TC 106/SC 4, Dental instruments, which keeps updated
records of all numbers currently allocated. An international group of experts will then decide on an appropriate
identification number for the instrument in question, including its specific characteristics. The Secretary will
inform the applicant, in due course, of the result and assist him in using the number correctly. The Secretariat
of ISO/TC 106/SC 4 can be contacted at:

Dentistry — Number coding system for rotary instruments —
Part 3:
Specific characteristics of burs and cutters
1 Scope
This part of ISO 6360 specifies the code numbers for specific characteristics of burs, finishing burs, cutters
and surgical instruments, which refer to the type of toothing on the working part of the instrument. This three
digit number appears in the locations 10 to 12 of the 15-digit overall number and forms the fourth group of
three digits in the 15-digit overall number, the principles of which are explained in ISO 6360-1 and 6360-2.
NOTE In addition to terms for rotary instruments and accessories used in two of the three official ISO languages
(English, French and Russian) this part of ISO 6360 gives the equivalent terms in the German language; these are
published under the responsibility of the member body for Germany (DIN). However, only the terms given in the official
languages can be considered as ISO terms.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

ISO 6360-2, Dentistry — Number coding system for rotary instruments — Part 2: Shapes
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 6360-1 and the following apply.
3.1
primary toothing
first toothing
toothing on the working part of the instrument which is the deepest toothing
NOTE The orientation of the helix is either in the left or right direction.
3.2
secondary toothing
toothing on the working part of the instrument with a toothing depth less than the primary toothing
3.3
crosscut
helicoidal crosscut
spiral cut
secondary toothing which is formed by a single uninterrupted helicoidal cut

SIST EN ISO 6360-3:2006
ISO 6360-3:2005(E)
NOTE Crosscuts can affect only the cutting edges of the primary toothing or can be lowered down to the root of the
primary toothing or even deeper. The pitch of the helix may be varied to achieve finer or coarser crosscuts. A crosscut
might be oriented either in left or right direction.
3.4
serpentine cut
special case of the crosscut
3.5
x-cut
double cut
staggered cut
secondary toothing which crosses the primary toothing
NOTE The angle of the helix is similar to the angle of the primary toothing in most cases. The orientation of the helix
is either the same as the orientation of the primary toothing or in the opposite direction.
3.6
diamond cut
secondary toothing with a toothing depth similar to the primary toothing
NOTE The angle of the helix is similar (approximately 45°) to the angle of the primary toothing but the orientation is in
the opposite direction.
4 Code numbers for specific characteristics
4.1 General
The general characteristics of the number coding system for rotary instruments are described in ISO 6360-1.
The first and second group of three digits of the 15-digit overall number are specified in ISO 6360-1.
The shapes of rotary instruments and their respective numbers are specified in ISO 6360-2 as the third group.
The fourth group of three digits identifies specific characteristics for groups of instruments.
The specific characteristics of burs, finishing burs, cutters and surgical instruments refer to the type of toothing
on the working part of the instruments. This is designated by a three-digit number, which appears in the
locations 10 to 12 of the overall 15-digit code number.
The code numbers identify the type of toothing of burs and cutters, including surgical instruments.
4.2 Type of toothing
The type of toothing on the working part is based on the following:
a) type of instrument: bur, finishing bur, cutter, surgical instrument;
EXAMPLE The toothing designations are: bur toothing, finishing bur toothing, cutter toothing, surgery toothing.
b) type of primary toothing:
1) direction of primary toothing: straight, left helicoidal, right helicoidal;
2) cutting direction of primary toothing: left cutting, right cutting;
3) grade of fineness of primary toothing: very fine, fine, medium, coarse, very coarse;
EXAMPLE The characteristics of the primary toothing are specified in several subsequent designations separated
by a comma, e.g. as “left helicoidal, right cutting, fine”.

---------------------- Page: 11 ----------------------

SIST EN ISO 6360-3:2006
ISO 6360-3:2005(E)
c) type of secondary toothing and additional characteristics: crosscut, x-cut, diamond cut, saw toothing;
1) direction of crosscut: left crosscut, right crosscut;
2) grade of fineness of secondary toothing: fine, medium, coarse.
EXAMPLE The characteristics of the secondary toothing are specified in one designation without separation by a
comma, e.g. as “fine right crosscut”.
“Right” or “left” refers to the direction of the toothing on the working part of the instrument, when viewed from
the shaft of the instrument.
The general designation of the geometric form of the rotary instruments goes from the shank to the working
part. This is illustrated with the shank on the right side of a figure and the working part on the left side of a
figure. Therefore in the following illustrations the designation “right” is on top of the figure, and the designation
“left” is on the bottom of the figure.
4.3 Default information
If no information is given, use the following default values:
a) without information on the cutting direction of the primary toothing, the cutting direction is right cutting.
b) without information on the grade of fineness of the toothing, the grade of fineness of the toothing is
medium;
c) without information on the direction of the crosscut, the direction of the crosscut is right crosscut.
5 Toothing of burs
Code numbers for the toothing of burs shall be as given in Table 1. The numbers, shown in Table 1, range
