Overview - ISO 10889-1:2004 (Tool holders with cylindrical shank)
ISO 10889-1:2004 is the first part of the ISO 10889 series that defines technical delivery conditions for tool holders with a cylindrical shank and a location bore. The standard specifies the interchangeability dimensions of the cylindrical shank and the mating location bore, the dimensions related to an optional data medium (identification/data chip fitting), and delivery, material and marking requirements. It is intended for tool holders used with machine tools with non-rotating tools, preferably on turning machines.
Key topics and technical requirements
- Interchangeability dimensions and tolerances: The standard provides dimension tables and figures for nominal shank diameters and lengths plus geometrical tolerances; unspecified details follow ISO 2768-m general tolerances.
- Location bore dimensions: Defined dimensions and tolerances for the mating bore to ensure accurate fit and repeatability.
- Data medium fitting: Dimensions and fitting position for an optional data medium (e.g., ID chip) are specified (figures and tables).
- Material and mechanical requirements:
- Minimum tensile strength for shank/tool-holder material: ≥ 900 N/mm².
- O-ring material: FPM, per ISO 1629.
- Surface treatment/hardening: Where hardened cylindrical shanks are required, surface hardness is specified as ~56 HRC with a hardening depth of at least 0.5 mm.
- Designation and marking: Formal designation format (reference to part, nominal diameter/length, type, optional H for hardened, D for data medium, O for O-rings) and indelible marking requirements (standard reference, characteristic dimensions, manufacturer).
- Scope of delivery: O-rings are not automatically included; if supplied they must be indicated in the designation.
Applications - who uses ISO 10889-1 and why
- Tooling manufacturers and machine-tool builders seeking standardized, interchangeable tool holders for lathes and turning centers.
- Production and tooling engineers specifying tool-holding systems to ensure compatibility across suppliers and reduce changeover time.
- Quality engineers and inspectors verifying dimensional conformity and interchangeability.
- Procurement professionals referencing standardized designations for ordering and supplier acceptance.
Practical benefits include simplified inventory, reliable tool positioning, repeatable machining accuracy, and easier integration of data-media-enabled tooling.
