Overview
ISO 5610-2:2014 - "Tool holders with rectangular shank for indexable inserts - Part 2: Style A" defines the geometry, designation and basic requirements for rectangular-shank tool holders with a straight shank and a 90° cutting edge angle (κ = 90°) used for side cutting in turning operations. The standard covers holders intended for indexable inserts (carbide or other cutting materials) mounted by clamping (screw or bore clamping). It is part of the ISO 5610 series that standardizes multiple tool-holder styles.

Key topics and technical requirements
- Scope and purpose: Specifies tool holder style A (straight shank, κ = 90°) primarily for turning with indexable inserts.
- Dimensions: Detailed dimension tables (Tables 1 and 2) for rhombic (shape C) and triangular (shape T) inserts; selection rules for height (h), width (b), length (l) and cutting edge length (l3).
- Designation system: Prescribes how to designate holders (reference to ISO 5610-2, mounting type, insert shape, style, clearance, hand, dimensions and cutting edge length). Example: Tool holder ISO 5610-2 – SCACR 1010 E06.
- Material: Recommends steel tool-holder material with tensile strength ≥ 1 200 N/mm².
- Mounting and clamping: Standard mounting types defined in the tables; custom mounting allowed by agreement (designation symbol adjusted according to ISO 5608).
- Corner radius and insert thickness: Guidance on compatible corner radii (nominal values listed) and insert thickness values (s) for standard designs; deviations must be specified at order.
- Tolerance and measurements: Tolerances for h, f and l measured with master insert and master shim as applicable.
- Delivery and marking: Holders delivered complete with clamping device but without inserts; marking must include manufacturer symbol and ISO 5610-2 reference on packaging.

Applications and users
- Practical for manufacturers and designers of lathe tooling and turning tool holders.
- Used by CNC programmers, tooling engineers, procurement and quality assurance teams specifying compatible holders and indexable inserts.
- Helps ensure interchangeability across suppliers for side-cutting turning operations using rhombic and triangular indexable inserts.
