Milling cutters - Interchangeability dimensions for cutter arbors or cutter mandrels
ISO 240:2016 specifies the dimensions for interchangeability between the cutter and the arbor or mandrel, i.e. the diameter of the bore and the arbor or mandrel and elements of the drive, whether by keying or tenon. It applies to all types of milling cutters mounted on cutter arbors or mandrels.
Fraises à métaux — Dimensions d'interchangeabilité avec les arbres porte-fraises ou les mandrins porte-fraise
L'ISO 240 :2016 prescrit les dimensions d'interchangeabilité de la fraise et de l'arbre ou du mandrin, c'est-à-dire le diamètre de l'alésage et de l'arbre ou du mandrin et les caractéristiques du mode d'entraînement, soit par clavetage, soit par tenons. Elle est applicable à tous les types de fraises à métaux montées sur les arbres porte-fraises ou sur les mandrins porte-fraise.

Overview
ISO 240:2016, titled "Milling cutters - Interchangeability dimensions for cutter arbors or cutter mandrels", is an international standard developed by the International Organization for Standardization (ISO). This third edition standard specifies precise dimensional criteria ensuring the interchangeability between milling cutters and their corresponding arbors or mandrels. It covers essential parameters such as the diameter of the bore, the arbor or mandrel, and the drive elements used for mounting, whether by keying or tenon methods. Applicable to all types of milling cutters mounted on arbors or mandrels, ISO 240:2016 facilitates compatibility and standardization in tooling components.
Key Topics
- Interchangeability Dimensions: Defines the exact measurements for cutter bore diameters and corresponding arbor or mandrel sizes.
- Drive Elements: Specifies tolerance and dimension requirements for key drive and tenon drive systems, ensuring secure and standardized mounting.
- Key Drive Dimensions:
- Includes bore diameter, key width, and height.
- Tolerances outlined for fitting precision (e.g., H7 for cutters and h6 for arbors).
- Detailed dimensional tables and figures supporting manufacturing accuracy.
- Tenon Drive Dimensions:
- Specifies measurements for tenon arbors and cutters including shoulder dimensions and tolerances.
- Ensures reliable assembly and mechanical engagement between components.
- Relation to ISO 13399: Annex A connects ISO 240 designations with ISO 13399 symbols, promoting standardized data representation and exchange in cutting tool technology.
Applications
ISO 240:2016 is essential for manufacturers and users of milling cutters and tooling systems seeking compatibility and interchangeability in tooling interfaces. Its practical applications include:
- Tool Design and Manufacturing: Assists machining tool manufacturers in creating components that fit universally, reducing the need for custom fittings.
- Machine Shops and Production Facilities: Enables quick, standardized replacement of milling cutters which minimizes downtime and maintains machining precision.
- Quality Control and Inspection: Provides clear measurement standards for assessing whether arbor and cutter interfaces meet international conformity.
- Supply Chain Optimization: Simplifies inventory management by standardizing mounting interfaces, enabling interchangeability across different machine and cutter brands.
- Technical Communication: Facilitates clear specifications and communication between manufacturers, engineers, and end-users via standards-compliant dimensions.
Related Standards
- ISO 13399 Series: Focuses on cutting tool data representation and exchange, providing a digital dictionary for tool designation and properties. ISO 240:2016 aligns with ISO 13399 to support consistent tooling data management.
- ISO/TS 13399-4: A technical specification within ISO 13399 addressing reference dictionaries specifically for adaptive tooling items, complementing ISO 240's dimensional details.
- Other ISO Standards in Small Tools (ISO/TC 29/SC 2): These cover various holding tools, adaptive components, and interfaces ensuring cohesive development in tooling standardization.
By adhering to ISO 240:2016, professionals in manufacturing and tooling gain assurance in the mechanical compatibility of milling cutters and their mounting systems, enhancing efficiency and precision in machining processes while ensuring global interoperability of standardized tooling components.

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.
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
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
