ISO 5611-11:2015

Overview

ISO 5611-11:2015 defines the geometric, material and marking requirements for cartridges, type A, style W used with indexable inserts. Style W cartridges are specified for end cutting with a cutting edge angle κr = 60° and are primarily intended for internal turning operations. The cartridges accept indexable inserts made of hard metal, ceramic or other cutting materials and are intended to be mounted in standard tool holders for turning.

Key topics and technical requirements

• Scope and purpose: Applies to type A cartridges with hole(s) for fastening screw(s), style W (κr = 60°) for end cutting.
• Dimensions and tolerance: Dimension tables and figures specify heights (examples: h = 6, 8, 10, 12, 16, 20, 25 mm), lengths and related key dimensions. Only the numerical dimensions must be respected - graphical depictions are illustrative.
• Material: Cartridges are required to be manufactured from steel with a specified minimum tensile strength (as shown in the standard).
• Design features:
  • Methods of insert retention (central screw, clamp, central hole) and related designation letters.
  • Provision for adjustment screws to correct the f dimension at manufacturer's option.
  • Compatibility with a range of insert corner radii (r) and insert edge lengths (l) as referenced in the tables; if an insert radius differs from the table, dimensions for f and l are to be determined according to ISO 5611-1.
• Designation rules: Standardized naming convention combining ISO reference, retention method, insert form, cartridge form (W), clearance, cutting direction, height, cartridge type (CA), length and insert size. Example: “Cartouche ISO 5611-11 – STWCR 12CA – 16”.
• Delivery and marking: Cartridges must be delivered complete with fastening hardware and any adjustment screws; marking must include characteristic letter(s) and manufacturer identification. The ISO 5611 number must appear on the packaging.

Applications and users

• Primary application: internal turning in metalcutting and machining centers where indexable inserts are used for efficient tool changes and edge replacement.
• Typical users:
  • Tool manufacturers and designers specifying cartridge geometry and retention modes.
  • Production engineers and machinists selecting cartridges for boring/internal turning operations.
  • Purchasing and quality teams ensuring compliance with standardized tooling components.
• Benefits: Ensures interchangeability, predictable tool geometry for process planning, and compatibility with a range of insert materials (hard metal, ceramics).
