Overview
ISO 22402-2:2022 is an international standard published by the International Organization for Standardization (ISO) that defines the dimensions and design requirements for medium-transfer units used in polygonal taper tool interfaces. This standard specifically addresses transfer units compatible with the polygonal taper systems outlined in the ISO 26623 series. These units are critical for enabling fluid transfer in wet processing applications and for interfacing machine tools with insert nuts.
The standard ensures interchangeability, reliability, and precision in tooling systems where polygonal tapers are employed, thereby supporting consistent manufacturing quality and operational efficiency in metalworking, machining, and other industrial processes.
Key Topics
Scope and Application
Specifies dimensions for medium-transfer units for polygonal taper interfaces suitable for wet processing environments and machine tool interfaces with insert nuts.Nominal Sizes
Defines transfer unit designs for nominal sizes ranging from 32 to 100 mm, covering a broad spectrum of tooling sizes typically used in industrial environments.Dimensional Specifications
Provides detailed measurements including diameters, thread sizes, lengths, and radii for each nominal size, ensuring precise fitting and optimal performance.Design Requirements
- Units must withstand pressures of at least 70 bar, suitable for high-pressure liquid transmission.
- Angular movement allowance of ±1° with minimal displacement force to support mechanical flexibility.
- Surface hardness of supply tubes must be at least 56 HRC (Rockwell Hardness C) to guarantee durability and wear resistance.
- Special design features such as lead-in chamfers, sliding sleeves for mounting (sizes 32 to 50), and polished surfaces to enhance sealing and mechanical stability.
Sealing and Assembly
Includes an assembly model with specified O-ring sizes for effective sealing of the transfer units, preventing leaks during fluid transfer under operational conditions.Designation System
A clear and standardized method for naming transfer units, for example:
Transfer unit ISO 22402-2 - 50 for a polygon-shank with a nominal size of 50 mm.
Applications
ISO 22402-2:2022 is essential for industries and engineers requiring standardized, reliable liquid transfer solutions in tool interfaces with polygonal tapers. Typical applications include:
Machine Tool Industry
Facilitating efficient liquid (coolant or lubricant) transfer in CNC machines, milling, and drilling operations using polygonal taper tool holders.Wet Processing Operations
Ensuring sealed and robust fluid transmission in cutting, grinding, or polishing processes where cooling or lubrication is vital.Precision Manufacturing
Maintaining tight dimensional tolerances and exchangeability of tooling components to guarantee consistent machining quality.Tooling Component Design and Manufacturing
Guiding OEMs and tooling manufacturers in producing transfer units compliant with international standards, thereby ensuring compatibility and performance.

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.
