Overview
ISO 10889-5:2016 defines the dimensions, designations and technical delivery conditions for tool holders with cylindrical shank - specifically Type D holders that have more than one rectangular seat (types D1 and D2). The standard applies to tool holders for machine tools with non-rotating tools, preferably for turning machines, and provides a consistent specification for manufacturing, procurement and quality control of multi-seat rectangular tool holders.
Key topics and technical requirements
- Scope and applicability: Covers Type D1 and D2 tool holders with more than one rectangular seat and cylindrical shank, referencing ISO 10889-1 for shank and location bore requirements.
- Dimensions and tolerances: All dimensions given in millimetres; tolerancing follows ISO 8015 principles and default tolerance classes per ISO 2768‑1 (linear/angular) and ISO 2768‑2 (geometrical) when not individually specified.
- Geometrical tolerances: Defined shapes and positional requirements for seats and interfaces are provided (figures and tables in the standard).
- Designation format: Standardized naming (e.g., “Tool holder ISO 10889-5 - D1 - 60 × 32”) to ensure unambiguous identification of type, nominal diameter and nominal height.
- Technical delivery conditions: Requirements for scope of delivery (includes clamping elements), design provisions (e.g., coolant supply with adjustable direction), and tool adjustability at right angles to the rectangular seat - design details are generally left to the manufacturer within the standard’s limits.
- Mapping to digital data: Annex A links ISO 10889-5 symbols to ISO 13399 (cutting tool data exchange) for CAD/CAM and data interoperability.
Practical applications
- Standardizes multi-seat rectangular tool holders used on turning machines and other lathes with non-rotating tooling.
- Supports manufacturers in producing interchangeable tool holders with predictable fit and function.
- Aids tooling buyers and procurement teams to specify and order correct tool holders and clamping elements.
- Facilitates quality assurance and inspection by providing dimensions and tolerance classes.
- Enables better integration with digital tool data systems via the ISO 13399 relationship for tooling libraries and CAM systems.
Who should use this standard
- Tool holder and cutting-tool manufacturers
- Machine tool builders and OEMs (turning machines)
- Production and tooling engineers specifying fixtures, holders and clamping systems
- Procurement, QA/QC and CAD/CAM data managers
