ISO 5610-9:2014

Overview

ISO 5610-9:2014 - Tool holders with rectangular shank for indexable inserts - Part 9: Style L defines the geometric, material and marking requirements for tool holders with rectangular shank, style L. Style L is characterized by an offset shank and a cutting edge angle κ = 95° for side and end cutting. The standard is intended primarily for tool holders that accept indexable inserts (typically carbide or other cutting materials) mounted by clamping for turning operations.

Key topics and technical requirements

• Scope and application: Tool holders for indexable inserts used in turning; illustrations and dimension tables for both rhombic (shape C) and hexagonal (shape W) inserts.
• Dimensions: Detailed dimension tables (Tables 1 and 2) for common tool sizes and cutting-edge lengths; reference to ISO 5610-1 for determining h, f, l and for additional length options.
• Cutting geometry: Style L defined by offset shank and 95° cutting-edge angle (end and side cutting).
• Designation rules: Standardized naming format (reference to ISO 5608) including mounting type, insert shape, tool style, clearance, hand (R/L), and h×b×l and cutting-edge length. Example codes provided (e.g., PCLNR 3225 P12).
• Material: Recommended tool-holder material is steel with tensile strength ≥ 1 200 N/mm².
• Mounting and clamping: Standard mounting types in the tables; clamping device included in delivery, indexable inserts are not included.
• Corner radius and insert thickness: Nominal corner radii and the corresponding cutting-edge lengths (Table 3); specified insert thicknesses apply to inserts without shims; deviations must be declared.
• Marking and delivery: Tool holders to be marked with manufacturer symbol and letter symbol; packaging should reference ISO 5610-9:2014.

Practical applications and users

ISO 5610-9:2014 is useful for:

• Tool manufacturers and designers - to design and produce interchangeable, compliant style L tool holders.
• CNC programmers and machinists - to select the correct holder for turning operations and ensure correct cutting geometry.
• Purchasing and quality assurance - to specify and verify incoming tool holders (designation codes, dimensions, material).
• Tooling engineers and machine shops - for standardized tooling inventory, compatibility across machines, and consistent performance when using indexable inserts (carbide or similar).

Practical benefits include improved interchangeability, predictable tool performance, simplified procurement, and reduced setup errors.
