Tapered die-sinking cutters with parallel shanks
Lays down the diemnsions of these cutters with plain parallel or parallel flatted shanks. The cutters are particular intended for directly obtained clearances of moulds, patterns and dies, when these exceed 2 52'. Applies to flat-end cutters and ball-nosed cutters. There are short type, medium type, and long type cutters.

Overview
ISO 3940:1977 is an international standard published by the International Organization for Standardization (ISO) that specifies the dimensions for tapered die-sinking cutters with parallel shanks. These specialized cutting tools are primarily used for creating precise clearances in moulds, patterns, and dies, particularly when those clearances exceed an angle of 2° 52'. The standard covers cutters with plain parallel shanks as well as those with parallel flatted shanks. ISO 3940:1977 includes dimensional guidelines for both flat-end and ball-nosed cutters, available in three types based on length: short, medium, and long.
This standard was developed by ISO Technical Committee ISO/TC 29, which focuses on small tools, and was officially released in June 1977. It ensures consistency and interchangeability in tooling used within manufacturing processes related to mould making and die-sinking.
Key Topics
- Types of Cutters: ISO 3940 defines three cutter types based on length-short, medium, and long-allowing users to select the appropriate cutter for specific machining applications.
- Shank Specifications: The standard addresses both plain parallel and parallel flatted shanks, with dimensional characteristics aligned with ISO 3338/1 to ensure compatibility with other milling cutter standards.
- Cutting Tool Geometry: The tapered cutters covered include flat-end cutters and ball-nosed cutters, which are critical for different finishing and contouring requirements in moulds and dies.
- Dimensional Tolerances: Specific tolerances such as h8 for plain parallel shanks and h6 for parallel flatted shanks are established to guarantee precision in tooling fit.
- Application Angle: The standardized cutters are intended for clearances greater than 2° 52', relevant to the shaping and finishing of mould components and die cavities.
Applications
ISO 3940:1977 cutters are essential in industries where precise mould-making and die-sinking are required, including:
- Mould and Die Manufacturing: Directly machining clearances in moulds and dies to exact specifications enhances product quality and tool life.
- Automotive and Aerospace Parts Production: Production of precision components often involves die-sinking operations that benefit from standardized cutters for repeatability and accuracy.
- Tool and Cutter Industry: Manufacturers use this standard to produce cutters that meet global quality and dimensional norms, facilitating international trade and tool compatibility.
- Metalworking and Machining Workshops: Shops engaged in small tool shaping rely on these standardized cutters to optimize machining processes and maintain consistency across jobs.
By adhering to ISO 3940, manufacturers and users improve operational efficiency, reduce tooling errors, and ensure interchangeability of critical machining cutters.
Related Standards
- ISO 3338/1: Specifies dimensional characteristics of plain parallel shanks for milling cutters, cited by ISO 3940 for shank compatibility.
- ISO 3338/2: Defines dimensional characteristics for parallel flatted shanks, also referenced for ensuring consistent shank designs with ISO 3940 cutters.
- Other ISO standards for Cutting Tools: Additional standards addressing milling cutters, drill bits, and tool holders provide a framework that supports comprehensive tooling standardization in manufacturing industries.

FOREWORD
ISO (the International Organization for Standardization) is a worldwide federation
of national Standards institutes (ISO member bodies). The work of developing
International Standards is carried out through ISO technical committees. Every
member body interested in a subject for which a technical committee has been set
up 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.
Draft International Standards adopted by the technical committees are circulated
to the member bodies for approval before their acceptance as International
Standards by the ISO Council.
International Standard ISO 3940 was developed by Technical Committee
ISO/TC 29, Sna// tools, and was circulated to the member bodies in November
1975.
