ISO 5611-6:2015

Overview

ISO 5611-6:2015 is an international standard developed by ISO that specifies requirements for cartridges, type A, style L, designed for indexable inserts used in metal cutting tools. These cartridges feature holes for fastening screws and a cutting-edge angle κr of 95° optimized for both side and end cutting. Primarily, these cartridges are intended for internal turning operations and are compatible with indexable inserts made from hard metal, ceramics, or other advanced cutting materials.

This 2015 edition is part 6 of the ISO 5611 series and provides precise dimensions, designations, materials, and design specifications specifically for style L cartridges. It supports manufacturers, tool designers, and end-users by ensuring interchangeability, consistent performance, and compatibility with a wide range of tool holders and inserts.

Key Topics

• Scope and Application
  ISO 5611-6 focuses on style L cartridges with a cutting edge angle of 95°, incorporating one or more holes for fastening screws. It applies specifically to type A cartridges used with indexable inserts for internal turning.

• Dimensions and Design
  The standard rigorously defines all critical dimensions (height, width, length, and mounting hole parameters) to maintain compatibility across manufacturers and tooling systems. It specifies tolerances and methods for measuring with master inserts and shims for precision. Dimensions such as cutting edge length and corner radius are also standardized.

• Material Requirements
  Cartridges must be constructed from steel with a minimum tensile strength of 1200 N/mm², ensuring durability under high machining loads.

• Designation System
  The document outlines a systematic alphanumeric code to identify the cartridge type, style, insert shape, method of holding, clearance angle, hand orientation, height, length, and indexable insert size. This uniform designation facilitates clear communication between suppliers and users.

• Design Features
  The cartridge design includes methods of holding inserts through screw clamping or hole clamping, with options for normal clearance angles of 0°, 7°, or 11°. It also allows for optional adjusting screws to fine-tune cartridge positioning.

• Marking and Delivery
  Each cartridge must be marked clearly with the manufacturer’s trademark and the corresponding ISO 5611 reference. Complete clamping devices and adjusting screws are included in the delivery scope.

Applications

• Internal Turning Operations
  ISO 5611-6 style L cartridges are primarily designed for internal turning processes, where precision and reliability in holding indexable inserts are critical.

• Manufacturing and Toolmaking
  Tool manufacturers use this standard to design and produce cartridges that meet stringent international criteria, facilitating global interoperability and quality assurance.

• Metal Cutting Industry
  Industries utilizing CNC turning centers, especially those machining internal diameters, benefit from standardized cartridges that ensure optimal cutting performance and tool life with various insert materials including carbide and ceramics.

Related Standards

• ISO 5611-1 – General survey and determination of dimensions for cartridges, providing fundamental measurement principles referenced by part 6.
• ISO 5608 – Designation system for turning and copying tool holders and cartridges, used for standardized coding in ISO 5611-6.
• ISO 1832 – Designation of indexable inserts for cutting tools, which pairs with ISO 5611-6 to identify compatible inserts by shape, clearance, and size.

Together, these standards form a comprehensive framework for the design, manufacturing, and application of indexable insert cartridges, ensuring consistent quality, interchangeability, and performance in precision machining.

By adhering to ISO 5611-6:2015, manufacturers and users of type A cartridges for style L indexable inserts can improve tool compatibility, machining accuracy, and operational efficiency in internal turning processes across various industrial sectors.
