ISO 5610-6:2014

Overview

ISO 5610-6:2014 defines the geometry, designation and basic requirements for tool holders with rectangular shank - Style G. Style G tool holders have an offset shank and a cutting-edge angle κ = 90° for side cutting. The standard applies to holders intended for indexable inserts (typically hard‑metal/carbide or other cutting materials) mounted by clamping and used in turning operations. ISO 5610-6 is one part of the ISO 5610 series covering multiple holder styles and cross-references ISO 5610-1 for general dimension rules.

Key Topics

• Scope and purpose: Standardizes tooling form and designation for Style G rectangular-shank holders used with indexable inserts for turning.
• Dimensions and profiles: Specifies dimensions for holders that accept rhombic (shape C) and triangular (shape T) inserts. (Detailed tables in the standard list height, width, cutting-edge length and other key dimensions.)
• Mounting types: Defines standard mounting/clamping types (e.g., screw-clamped, bore-clamped) and notes manufacturer or agreement-based variants.
• Designation rules: Specifies how to code a tool holder designation (reference to ISO 5610-6, mounting type, insert shape, style, clearance, hand, h × b × l and cutting-edge length). Example designations are given (e.g., SCGCR 1010 E06).
• Material and mechanical requirements: Recommends steel with minimum tensile strength (≥ 1 200 N/mm²) for tool holder material.
• Corner radius and insert thickness: Provides nominal corner‑radius guidance (tabled r values tied to cutting-edge lengths - e.g., nominal r 0.4, 0.8, 1.2 mm with inch conversions) and required insert thickness values for standard designs.
• Marking and delivery: Tool holders are delivered with clamping devices but without inserts; marking must include manufacturer symbol and packaging shall reference ISO 5610-6:2014.

Applications

• Manufacturers and designers of turning tool holders and tool‑holding systems.
• Tooling suppliers and distributors who specify, stock or label standard tool holders for CNC and manual lathes.
• Machining engineers and CAM programmers selecting holder/inserts combinations for side‑cutting turning operations.
• Purchasing and quality teams ensuring interchangeability, correct designation and compliance with international tooling practices.
