Overview
ISO 5611-12:2015 specifies cartridges, type A, style Y, for use with indexable inserts. Style Y cartridges are designed for end cutting with a cutting edge angle κr = 85° and are primarily intended for internal turning operations. Cartridges accommodate indexable inserts made of hard metal, ceramic or other cutting materials and define dimensions, design features, material and marking requirements to ensure interchangeability and safe mounting.
Key topics and requirements
- Scope and purpose: Applies to Type A cartridges with hole(s) for fastening screw(s), style Y (κr = 85°) for internal turning.
- Dimensions: Detailed dimensional tables and figures cover cartridge heights (examples: h = 6, 8, 10, 12, 16, 20, 25 mm), insert geometries (rhombic, triangular, square), and dimensional tolerances. For certain dimensions (h, f, l) refer to ISO 5611-1 for determination.
- Designation: Standardized designation format (e.g., Cartridge ISO 5611-12 – CSYPR 12CA – 12) combining method of holding, insert shape, style (Y), normal clearance, hand (R/L), height and insert size - enabling consistent product identification.
- Material: Cartridge bodies shall be made of steel with tensile strength of at least 1 200 N/mm².
- Design features:
- Methods of holding: top clamping, hole clamping or screw clamping depending on insert clearance (α = 7°, 11°, or 0°) and letter symbols (C, S, P).
- Corner radius (r): accommodation for a range of corner radii; specific values and guidance referenced in the standard and ISO 5611-1.
- Optional adjusting screw for f-dimension adjustment.
- Extent of delivery and marking: Delivered with complete clamping device and adjusting screws; cartridges must be marked with the letter symbol and manufacturer name/trademark. Packaging shall reference the general number ISO 5611.
Applications and users
ISO 5611-12:2015 is useful for:
- Tooling and cutting-tool manufacturers designing or producing cartridges (type A) for indexable inserts.
- Machine tool builders specifying internal turning tool systems.
- Tooling engineers, procurement and quality teams who require standardized cartridge dimensions, designation and materials for interchangeability.
- Production and maintenance departments performing internal turning work using inserts of hard metal or ceramic.
Benefits include reliable interchangeability, clearer product specification, and improved compatibility between cartridges and indexable inserts.
