ISO 5610-10:2014

Overview

ISO 5610-10:2014 defines tool holders with rectangular shank - Style N for use with indexable inserts. Style N tool holders have a straight (rectangular) shank and a side-cutting cutting edge angle κ ≈ 63°. The standard is part of the ISO 5610 series and covers dimensional specifications, designation, material and basic design requirements for tool holders intended for turning operations with indexable inserts (hard metal or other cutting materials).

Keywords: ISO 5610-10, tool holders, rectangular shank, indexable inserts, style N, cutting edge angle 63°, turning operations.

Key topics and technical requirements

• Scope and intent: Specifies style N tool holders for side cutting with indexable inserts used in turning.
• Dimensions: Provides dimension tables and pictorial representations for tool holders used with rhombic (shape D) and triangular (shape T) inserts. Dimension symbols are aligned with ISO 5610-1 and ISO/TS 13399 references.
• Cutting edge geometry: Cutting edge angle κ = 62.5° ± 1° (≈ 63°) for certain neutral holders; recommended rake and inclination angles are shown but may vary by application.
• Designation: Prescribes systematic designation format (reference to ISO 5610-10, mounting type, insert shape symbol, tool style, clearance symbol, hand, height h, width b and tool length l, and cutting-edge length l3). Example codes (from the standard): PDNNR 4032 P15, PTNNR 4032 M22.
• Material: Tool holder material should be steel with a tensile strength of at least 1 200 N/mm².
• Design details:
  • Standard mounting types per the tables; non‑standard mounting by agreement.
  • Corner radius (r) guidance and mapping to cutting-edge length (nominal r values shown; inch-derived conversions given as 0.397 mm and 0.794 mm).
  • Insert thickness (s) values apply to inserts without shims; deviations must be specified when ordering.
• Delivery & marking: Tool holders are delivered complete with clamping device but without inserts. Marking must include manufacturer symbol and the part reference ISO 5610-10:2014 on packaging.

Applications and users

• Primary users:
  • Tooling manufacturers and machine-tool designers specifying standardized tool holder geometry.
  • CNC programmers, production engineers and tooling buyers selecting holders for turning operations.
  • Quality and procurement teams ensuring interchangeability and compatibility of holders and inserts.
• Typical use cases:
  • Turning and facing operations using indexable carbide inserts mounted by clamping.
  • Environments that require standardized interchangeability between holders and insert types (rhombic D, triangular T).

Related standards

• ISO 5610-1 - general survey and dimension correlation
• ISO 5608 - designation of turning tool holders and cartridges
• ISO/TS 13399-2 / -3 - cutting tool data dictionaries
• ISO 883, ISO 3364, ISO 6987 - indexable insert dimensions and fixing features

This standard helps ensure consistent fit, safe clamping and interchangeability of rectangular-shank tool holders (Style N) for indexable inserts in turning applications.
