ISO 5611-2:2015

Overview

ISO 5611-2:2015 is an international standard developed by ISO that specifies the requirements for cartridges, Type A, Style F, designed for use with indexable inserts. These cartridges feature one or more holes for fastening screws and possess a cutting edge angle κr of 90°, which is ideal for end cutting applications. Primarily, these cartridges are intended for internal turning operations using indexable inserts made from hard metal, ceramic, or other advanced cutting materials. ISO 5611-2:2015 defines their dimensions, design, materials, and marking to ensure interchangeability and consistent performance in precision machining.

Key Topics

• Scope and Application
  Applies specifically to Type A cartridges with screw holes for fastening, Style F, with a 90° cutting edge angle suited to end cutting during internal turning. Used with a variety of cutting inserts such as hard metal and ceramics.

• Dimensions and Design
  The standard provides detailed dimensional guidelines including height (h), width, length (l), and other critical geometric parameters. Tolerances are specified for precision compatibility with inserts and tool holders. The design includes a recommended material strength of at least 1200 N/mm² tensile strength steel to withstand rigorous machining forces.

• Retention Methods
  Covers methods for insert retention, primarily central screw hole fixation, ensuring secure mounting of indexable inserts for stability during cutting.

• Cutting Edge Radius
  Cartridge compatible insert cutting edge radii are defined with nominal values and their corresponding dimensions for precise tooling requirements.

• Adjustment and Fastening
  Provision for adjustment screws is recommended, allowing manufacturers to equip cartridges for fine-tuning cutting insert positioning.

• Delivery and Marking
  Cartridges must be delivered complete with fastening devices and adjustment screws. Clear marking including manufacturer's name or trademark and characteristic letters per ISO 5608 ensures traceability and conformity.

Applications

ISO 5611-2:2015 cartridges are fundamental in the manufacturing sector for high-precision internal turning operations. Their strict dimensional requirements and standardized design enable efficient use with indexable inserts in diverse materials such as:

• Hard metals and cemented carbides
• Ceramics and advanced cutting composites

Industries leveraging this standard include automotive, aerospace, heavy machinery, and tool manufacturing, where trustworthy, repeatable internal turning tools are essential for productivity and product quality. The standard facilitates machine tool setup, predictable tool wear, and optimized cutting performance in demanding machining environments.
