Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work o f 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 o f
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
di fferent types o f ISO documents should be noted. This document was dra fted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some o f the elements o f this document may be the subject o f
patent rights. ISO shall not be held responsible for identi fying any or all such patent rights. Details o f

any patent rights identified during the development o f the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is in formation given for the convenience o f users and does not

constitute an endorsement.

For an explanation on the meaning o f ISO specific terms and expressions related to con formity

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary in formation
The committee responsible for this document is ISO/TC 29, Small tools, Subcommittee SC 2, Holding
tools, adaptive items and interfaces.
This third edition cancels and replaces the second edition (ISO 10889-7:2004), of which it constitutes
a minor revision, notably with the addition o f Annex A, which gives the relationship between the
designations of this part of ISO 10889 and the ISO 13399 series.
ISO 10889 consists of the following parts, under the general title Tool holders with cylindrical shank:
— Part 1: Cylindrical shank, location bore — Technical delivery conditions
— Part 2: Type A, shanks for tool holders of special designs
— Part 3: Type B with rectangular radial seat
— Part 4: Type C with rectangular axial seat
— Part 5: Type D with more than one rectangular seat
— Part 6: Type E with cylindrical seat
— Part 7: Type F with taper seat
— Part 8: Type Z, accessories

These sizes have a recess for taper shanks with flat tang up to the end face o f the cylindrical shank. The design o f slot is

at the discretion of the manufacturer.

4 Designation
A type F tool holder with Morse taper seat in accordance with this part o f ISO 10889 shall be designated
by the following:
a) “tool holder”;
b) re ference to this part o f ISO 10889, i.e. ISO 10889-7;
c) type (F);

d) nominal diameter, d1 , in millimetres;
e) internal taper type;

f) if applicable, hardened contact surface (H).
EXAMPLE 1 A type F tool holder with a Morse taper seat, a nominal diameter, d1
taper, type BIK 3, is designated as follows:

= 40 mm, and an internal

Tool holder ISO 10889-7 - F - 40 - MT-BIK 3

EXAMPLE 2 A type F tool holder with a Morse taper seat and nominal diameter, d1 = 40 mm, an internal taper,
type BIK 3, and hardened contact sur face is designated as follows:

Tool holder ISO 10889-7 - F - 40 - MT-BIK 3 H

5 Technical delivery conditions
As a complement to the requirements o f ISO 10889-1, the following requirements also apply.

The taper socket shall be hardened with a surface hardness of (56 +04 ) HRC and a depth of hardening of
at least 0,5 mm.
The taper angle tolerance class of taper socket shall be AT5 in accordance with ISO 296.
Tool holders can also be supplied with hardened contact surface.
