Overview
ISO 702-1:2009 - Machine tools - Connecting dimensions of spindle noses and workholding chucks - Part 1: Conical connection - specifies the sizes and tolerances required for interchangeability between conical spindle noses and the corresponding connecting faces of face plates or workholding chucks. This part of ISO 702 defines standardized connecting dimensions, bolt circles, fixing-hole patterns and fits to ensure compatible mounting across manufacturers and regions. All dimensions and tolerances are expressed in millimetres.
Key topics
- Scope and purpose: Defines sizes for interchangeability of conical spindle noses and mating face plates/workholding chucks (size numbers No. 3–28).
- Dimensional tables: Detailed tables list nominal diameters (d), bolt-circle diameters, axial lengths and other key dimensions for each size. Example nominal d values include 53.975 mm, 63.513 mm, 82.563 mm, up to 584.225 mm.
- Tolerances and fits: Tolerance classes (e.g., H8/h8 for some fits), plus general tolerance guidance (untoleranced dimensions ±0.4 mm).
- Bolt circles and fixing holes: Definitions for inner and outer bolt circles, fixing-screw sizes and positions (Type A arrangements and Type 1/Type 2 connecting face variants).
- Metric / inch interchangeability: Tables permit interchangeability between metric and inch-based chucks - compromise dimensions and notes are provided to accommodate both systems.
- Type identification: Face plates and chucks should be marked with the connection type to ensure correct matching.
Applications
ISO 702-1 is intended for use where reliable, repeatable mechanical connections are critical:
- Machine tool OEMs specifying spindle noses and mounting interfaces.
- Chuck and face-plate manufacturers designing to standardized connecting dimensions.
- Fixture and tooling designers ensuring compatibility between workholding devices and spindles.
- Maintenance and retrofit teams replacing chucks or upgrading spindles while preserving interchangeability.
- Purchasing and quality assurance teams verifying supplier parts conform to international machine tool standards.
Benefits include improved interchangeability of spare parts, reduced machine downtime, simplified procurement and global compatibility of workholding systems.

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 702-1 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 8, Work
holding spindles and chucks.
This third edition cancels and replaces the second edition (ISO 702-1:2001), Tables 1 and 2 and Figures 1
and 2 of which have been technically revised.
ISO 702 consists of the following parts, under the general title Machine tools — Connecting dimensions of
spindle noses and work holding chucks:
⎯ Part 1: Conical connection
⎯ Part 2: Camlock type
⎯ Part 3: Bayonet type
⎯ Part 4: Cylindrical connection
In this corrected version of ISO 702-1:2009, the “−” (minus) sign has been deleted from the zero values of
tolerance of d in Table 1 and footnote “c” of Table 2 has been corrected to read “Type A1” and “Type A2”.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
L'ISO 702-1 a été élaborée par le comité technique ISO/TC 39, Machines-outils, sous-comité SC 8, Broches
porte-pièce et mandrins.
Cette troisième édition annule et remplace la deuxième édition (ISO 702-1:2001), dont les Tableaux 1 et 2, et
les Figures 1 et 2 ont fait l'objet d'une révision technique.
L'ISO 702 comprend les parties suivantes, présentées sous le titre général Machines-outils — Dimensions
d'assemblage des nez de broche et des mandrins porte-pièces:
⎯ Partie 1: Assemblage conique
⎯ Partie 2: Type Camlock
⎯ Partie 3: Type baïonnette
⎯ Partie 4: Assemblage cylindrique
Dans la présente version corrigée de l'ISO 702-1:2009, le signe moins «−» a été supprimé des valeurs «0»
pour les tolérances de d dans le Tableau 1 et la note de bas de tableau «c» du Tableau 2 a été corrigée pour
lire «Type A1» et «Type A2».
