Overview
ISO 2585:1972 specifies the dimensional requirements for slotting cutters with plain bore and key drive - metric series. It covers slotting cutters intended to fit cutter arbors and defines the metric dimensions for bodies with straight-sided or helical teeth. The standard aligns the recommended range of outside diameters with ISO/R 523 and references bore and keyway interchangeability from ISO/R 240.
Key topics and requirements
- Scope: Metric-series slotting cutters designed for mounting on cutter arbors using a plain bore and key drive. Tooth form (straight or helical) is left to the manufacturer’s choice.
- Dimensional data: Dimensions are expressed in millimetres and follow the metric series conventions adopted from ISO/R 523 for outside diameters.
- Bore and keyway: Bore and keyway dimensions must conform to the metric series specified in ISO/R 240 to ensure interchangeability with standardized cutter arbors and mandrels.
- Thickness tolerance: The tolerance on cutter thickness (L) is not fixed in the standard; it is to be agreed between the supplier and purchaser depending on the tolerance required for the machined part.
- Interchangeability focus: Emphasis on compatibility between cutters and arbors to support modular tooling systems and predictable mounting geometry.
Practical applications
ISO 2585 is used where standardized dimensions and fit between slotting cutters and cutter arbors are essential. Typical users and applications include:
- Tool manufacturers producing metric slotting (slitting) cutters for general milling operations.
- Machine shops and metalworking factories that mount cutters on arbor systems for slotting, keyway cutting, and similar milling tasks.
- Tooling engineers and purchasing/specification teams ensuring interchangeability and consistent procurement across suppliers.
- Quality and inspection teams verifying dimensional conformity to international standards.
Benefits for users:
- Simplifies selection and replacement of cutters across different suppliers.
- Reduces fitment errors and scope for rework by aligning bore/keyway dimensions with ISO/R 240.
- Supports modular tooling systems and standard inventory practices.
