Overview
ISO 2296:2018 specifies the dimensions and mechanical characteristics of metal slitting saws (metric series) with fine and coarse teeth. The standard covers dimensional tolerances, tooth pitch and tooth count relationships, and options for hub, keying and drive features. It applies to both fine-tooth and coarse-tooth metal slitting saws and includes guidance for extending tooth-series ranges according to the graph in Annex A.
Key topics and requirements
- Scope and types: Defines two types - metal slitting saws with fine teeth and with coarse teeth (metric series).
- Dimensions and tolerances: Provides dimensional requirements for outside diameter, bore/hub diameters and cutting width (see Figure 1 and Tables 1–2 in the standard).
- Number of teeth and pitch: Specifies the relationship between tooth count and pitch for given saw diameter and thickness. The ratio of coarse-tooth number to fine-tooth number is 0.5. Annex A contains a graph to determine pitch or number of teeth by diameter and thickness.
- Mechanical characteristics:
- Side relief: May be provided up to the bore or hub at manufacturer’s discretion.
- Keying: Saws are normally supplied without keyways; if required, keyway dimensions follow ISO 240 and are by agreement between user and manufacturer.
- Pin‑hole drive: For diameters d = 200 mm, 250 mm and 315 mm pin hole drives may be specified; hole positions and sizes follow ISO 2924.
- Interoperability mapping: Annex B maps designations in ISO 2296 to data elements in ISO 13399 (cutting tool data exchange).
Practical applications and users
Who uses ISO 2296:2018:
- Tool manufacturers producing metric metal slitting saws.
- CNC and machine-shop engineers specifying saw geometry (diameter, thickness, tooth count/pitch).
- Purchasing and quality assurance teams ensuring interchangeability and conformity.
- CAD/CAM and tooling-data managers mapping tool properties to ISO 13399 data schemas.
How it’s used in practice:
- Selecting the correct tooth pitch/number for slotting operations based on saw diameter and material thickness.
- Specifying bore, hub and mounting tolerances for reliable spindle fit and drive engagement.
- Defining optional features (keyway, pin-hole drive) to match machine arbors per ISO 240 and ISO 2924.
- Standardizing tool data exchange using the relationships provided to ISO 13399.
Related standards
- ISO 240 - Milling cutters: interchangeability dimensions for cutter arbors/mandrels (keyway dimensions).
- ISO 2924 - Solid and segmental circular saws: drive hole patterns for certain diameters.
- ISO 13399 - Cutting tool data representation and exchange (Annex B mapping).
ISO 2296:2018 is a practical reference for ensuring dimensional compatibility, correct tooth selection and mechanical interface specifications when designing, buying or manufacturing metric metal slitting saws.
