Overview
ISO 5610-13:2014 defines tool holders with rectangular shank - Style T for use with indexable inserts. It covers holders with an offset (offset) shank and a cutting edge angle κ = 60° intended primarily for side cutting in turning operations. The standard specifies dimensional data, designation rules, material and basic design requirements, mounting types, and marking and delivery conditions for these tool holders.
Key topics and technical requirements
- Scope and geometry
- Style T is for triangular indexable inserts (shape T) used for turning with a 60° cutting-edge angle.
- Figures and tabulated dimensions define nominal sizes (height h, width b, cutting-edge length l, etc.) and typical tool profiles.
- Dimensions and tolerances
- Dimensional tables give recommended nominal sizes and the symbols used; conformity to specified dimensions is required even if pictorial representations are illustrative.
- For certain dimensions (h, f, l) ISO 5610-1:2014 is referenced for determination and tolerances.
- Designation
- A standardized designation format is required (example: Tool holder ISO 5610-13 - PTTNR 3225 P16) including mounting type, insert shape, style, clearance, hand, height/width, and length.
- Material
- Recommended material: steel with tensile strength ≥ 1 200 N/mm².
- Design & mounting
- Standard mounting types and clamping arrangements are specified; modified mountings are possible by agreement with corresponding changes noted in designation.
- Tool holders are delivered with clamping device but without inserts.
- Corner radius and insert thickness
- Specified corner radii for common cutting-edge lengths (example: l = 11 → r = 0.4 mm; l = 16.5 → r = 0.8 mm; l = 22 → r = 1.2 mm); other radii require dimensional adjustment per ISO 5610-1.
- Insert thickness values in tables apply to inserts without a shim; deviations must be indicated at ordering.
- Marking
- Tool holders must be marked with the letter symbol and manufacturer name/trademark; packaging must reference ISO 5610-13:2014.
Applications and users
- Primary users:
- Cutting tool manufacturers designing and producing rectangular-shank holders.
- CNC toolroom engineers and manufacturing engineers specifying tooling for turning operations.
- Procurement and quality personnel ensuring compatibility, interchangeability and adherence to international tooling specs.
- Practical uses:
- Standardized selection and ordering of tool holders for lathe turning operations using triangular indexable inserts.
- Ensuring interchangeability between suppliers and compatibility with data-exchange systems for tooling (CAD/CAM, tool libraries).
