ISO 5610-3:2014

Overview

ISO 5610-3:2014 - "Tool holders with rectangular shank for indexable inserts - Part 3: Style B" defines the geometry, designation and basic requirements for straight rectangular-shank tool holders (style B) with a cutting edge angle κ = 75° for side cutting. The standard targets holders intended for indexable inserts (typically hardmetal/carbide or similar cutting materials) mounted by clamping and used in turning operations.

Key topics and technical requirements

• Scope and application: Tool holders with straight rectangular shank for side cutting in turning operations; intended for indexable inserts mounted by clamping.
• Dimensions and figures: Detailed dimensional tables and pictorial representations for two insert shapes:
  • Rhombic (shape C)
  • Square (shape S) Only the tabulated dimensions are mandatory; pictorials are illustrative.
• Cutting geometry: Cutting edge angle κ = 75°; recommended rake and inclination angles are shown but may vary by application.
• Designation system: Prescribes a structured designation code (tool holder ISO 5610-3 - [type][insert shape][style][clearance][hand][hxb][length][cutting edge length]) - examples are provided in the standard.
• Material: Recommends steel with a tensile strength of at least 1 200 N/mm² for the tool holder body.
• Mounting and delivery: Standard mounting types are listed in the dimensional tables; tool holders are delivered complete with clamping device but without inserts. Alternative mounting styles are allowed by agreement.
• Corner radii and insert compatibility: Specifies nominal corner radius values for standard cutting edge lengths (e.g., l = 6.4 mm → r ≈ 0.4 mm; l = 12.7/15.88 mm → r ≈ 1.2 mm); other radii require dimension determination per ISO 5610-1.
• Tolerances and measurement: Tolerances for key dimensions are referenced to measurements made with master inserts and shims where applicable.
• Marking: Holders must be marked with manufacturer’s symbol and packaging must reference ISO 5610-3:2014.

Applications and users

• Practical for manufacturers and suppliers of turning tool holders, machine-tool engineers, tooling buyers, and CAM/tooling data engineers.
• Typical uses: external and side turning operations where a rectangular-shank holder with a 75° side-cutting geometry is required, and where compatibility with standard indexable inserts and clamping systems is needed.
• Useful for quality control, procurement specifications, toolroom design and CAD/CAM tool libraries.
