ISO 5610-12:2014

Overview

ISO 5610-12:2014 specifies tool holders with rectangular shank - Style S: holders with an offset shank and a cutting edge angle κ = 45° intended for side cutting in turning operations. The standard covers holders designed for indexable inserts (hard metal or other cutting materials) that are mounted by clamping. It defines the dimensional series, designation rules, material requirement and key design features to ensure interchangeability and correct selection for turning tooling systems.

Key topics and technical requirements

• Scope and purpose: Style S tool holders for turning operations using indexable inserts with a 45° cutting edge angle for side cutting.
• Insert shapes covered: Rhombic (C), Square (S) and Round (R) indexable insert shapes - specific figures and dimension tables are provided for each shape.
• Dimensions and tables: Detailed dimension tables (height h, width b, cutting edge length l, insert thickness s, diameter d where applicable) and pictorial representations; only the numeric dimensions are mandatory.
• Designation rules: Standardized naming/part-number format combining mounting type, insert shape, tool style, normal clearance, hand (L/R), tool height/width/length and cutting edge length (examples provided in the standard).
• Material: Recommended steel with tensile strength of at least 1 200 N/mm² for tool holder bodies.
• Design features: Mounting types (screw-clamped, bore-clamped, countersunk, etc.) follow tables in the document; manufacturers may provide variations by agreement. Corner radius (r) and allowable insert radii mapping are specified; insert thickness (s) and compatibility considerations are addressed.
• Delivery and marking: Extent of delivery and marking requirements ensure traceability and correct identification.

Practical applications

• Selecting or specifying compatible tool holders for CNC turning and lathe operations where side cutting with a 45° approach angle is required.
• Ensuring interchangeability between suppliers by using ISO-compliant dimensioning and designation codes.
• Tooling design and CAD/CAM libraries for tool path programming and tooling assembly.
• Procurement and quality control: unambiguous part identification, acceptance criteria and compatibility checks.

Who should use this standard

• Tooling manufacturers and designers
• CNC programmers and process engineers
• Machine shop buyers and tooling procurement teams
• Quality/inspection engineers and standards managers
• CAD/CAM library maintainers and tooling system integrators

Related standards

• ISO 5608:2012 - designation for turning and copying tool holders
• ISO 5610-1:2014 - general survey, correlation and determination of dimensions for rectangular-shank tool holders
• ISO/TS 13399 series - digital representation and preferred symbols for cutting-tool data

Using ISO 5610-12 helps ensure consistent tooling selection, reliable mounting and clear identification of rectangular-shank tool holders for indexable inserts in turning applications.
