ISO 5611-7:2015

Overview

ISO 5611-7:2015 specifies requirements for cartridges, type A, style R, used with indexable inserts. The standard covers cartridges with hole(s) for fastening screw(s) and a cutting edge angle κr = 75° for side cutting. These cartridges are intended for use with indexable inserts made of hard metal, ceramic or other cutting materials and are primarily mounted for internal turning operations.

Keywords: ISO 5611-7:2015, cartridges type A, style R, indexable inserts, cutting edge angle 75°, internal turning, cutting tool cartridges.

Key topics and technical requirements

• Scope and application: Cartridges type A, style R (κr = 75°) for side cutting, intended for internal turning using indexable inserts.
• Dimensions and pictorial limits: Specific dimensional tables and sectional drawings define heights (h), lengths (l), and related dimensions; cartridges need only observe the specified dimensions (pictorials are illustrative).
• Designation system: A formal designation format is provided combining ISO part reference, holding method, insert shape, style, clearance, hand, tool height, cartridge type and insert size (example: Cartridge ISO 5611–7 – CSRPR 12CA – 12).
• Materials: Cartridge bodies are specified as steel with a minimum tensile strength of 1 200 N/mm².
• Methods of holding: Defined holding/clamping methods mapped to letter symbols (top clamping, screw clamping through hole, hole clamping) and correlated to insert normal clearances (α = 7°, 11°, 0°).
• Corner radius and inserts: Guidance on allowable corner radii for compatible insert sizes; where non-standard radii are used, dimensions a, f and l shall be determined per ISO 5611-1.
• Adjustment and delivery: Manufacturer option to include an adjusting screw for f-direction adjustment; cartridges are delivered with complete clamping devices and adjusting screws where applicable.
• Marking: Cartridges must be marked with the letter symbol and manufacturer name/trademark; ISO 5611 general number should appear on packaging.

Applications and users

• Intended users:
  • Cutting tool designers and manufacturers
  • Toolroom engineers and production machining planners
  • CNC programmers and machine-shop buyers
  • Quality and compliance teams specifying tooling to standards
• Typical applications:
  • Internal turning operations requiring indexable inserts
  • Retrofit or design of tool holders that must match standardized insert geometries and clearances
  • Procurement and part interchangeability across suppliers
