Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
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.
International IS0 15488 was prepared by Technical Committee lSO/‘lC 29, Small too/s.
Annex A forms an integral part of this International Standard.

INTERNATIONAL STANDARD @ IS0 IS0 15488: 1996(E)
Collets with 8” setting angle for tool shanks - Collets, nuts and fitting dimensions
1 Scope
This International Standard specifies the dimensions, materials and manufacturing requirements, and designation of collets for tools with parallel shanks and their corresponding holders and nuts. For non-standardized clamping devices, such as clamping devices specified in drawings, these holders can be agreed upon between customer and supplier.
Form A applies to milling and any other application where a hard collet bore is required, provided that the clamping range of hl0 be sufficient.
Form B applies for general purpose where an extended clamping range is required.
2 Normative reference
The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards.
IS0 2768-l :I 989, General tolerances - Par? I: Tolerances for linear and angular dimensions without individual tolerance indications.
3 Dimensions
Collets, holders and nuts need not correspond to figures 1 to 3 ; only the given dimensions shall be complied with.
General tolerances: IS0 2768-l - m
