Overview
ISO 5610-11:2014 defines tool holders with rectangular shank - Style R for use with indexable inserts. Style R is characterized by an offset shank and a cutting-edge angle κ = 75° intended for side cutting in turning operations. The standard specifies dimensions, designation, material, design features, delivery content and marking rules for these holders, and is part of the broader ISO 5610 series covering multiple tool-holder styles.
Key topics and technical requirements
- Scope and geometry
- Tool holders with rectangular shank, style R (offset shank, κ = 75°) primarily for indexable inserts made of hard metal or other cutting materials.
- Figures and dimensional tables define heights, widths, lengths and cutting-edge lengths for standard sizes; actual dimensioning references ISO 5610-1 for correlation and determination.
- Designation and marking
- Clear designation format is required (reference to ISO 5610-11, mounting type, insert shape, tool style, clearance, hand, dimensions and cutting-edge length).
- Example: Tool holder ISO 5610-11 - PSRNR 3225 P15.
- Marking must include the letter symbol and manufacturer name/trademark; packaging should reference ISO 5610-11:2014.
- Material and delivery
- Recommended material: steel with tensile strength ≥ 1 200 N/mm².
- Tool holders are delivered complete with clamping device, but without indexable insert(s).
- Design tolerances and inserts
- Corner radii and cutting-edge lengths have nominal pairings (e.g., 9.52 mm → 0.8 mm; 12.7 / 15.88 mm → 1.2 mm; 19.05 / 25.4 mm → 2.4 mm; note: more precise converted values are provided).
- Insert thickness values in tables apply to inserts without shims; non-standard thicknesses must be specified when ordering.
- Mounting and handedness
- Supports right-hand and left-hand tool holders (figures show right-hand orientation; left-hand is laterally reversed).
- Type of mounting follows ISO 5608 conventions, with manufacturer-agreed modifications allowed.
Applications and users
- Intended for manufacturers and designers of turning tool holders, tooling engineers, toolroom managers and CAM programmers specifying tooling for lathe and turning centers.
- Typical uses: external and side turning where indexable carbide (hardmetal) inserts are clamped for efficient, repeatable cutting performance.
- Useful for procurement teams standardizing tooling and for CAD/CAM libraries that require standardized geometry and designation.
