Cross-brand geometric interchange
Under ISO 1832, every insert carrying the core designation RCKX060400 shares identical geometry — shape, inscribed circle, thickness and nose radius — regardless of manufacturer. Letters after a dash (chipbreaker patterns, grade numbers) affect chip control and application band, not the pocket geometry, and are marked PARTIAL.

Grade cross-reference (ISO 513)
Geometry swaps are safe; grade swaps need review. Grades are mapped only within the same ISO 513 workpiece group and application band, and every mapping is cited. Verified catalog mappings for this geometry are added row by row.

Typical operations
- profile turning
- high-feed turning
- hard turning
Small inscribed circle — typically finishing, small parts and precision operations.
Workpiece materials
All ISO 513 workpiece material groups (P/M/K/N/S/H) depending on the selected carbide grade.
CVD-coated grades are typical for steel (P) and cast iron (K) general turning; PVD-coated grades are typical for stainless (M), superalloys (S) and finishing cuts. Always apply the manufacturer's cutting-data recommendation for the chosen grade.
Selection notes
- ▸Geometry first, grade second. The same ISO core code is a drop-in pocket fit across brands; the chipbreaker suffix and grade decide performance and must be matched to the cut.
- ▸Nose radius is a trade-off. A larger rε strengthens the edge and allows higher feeds but raises radial cutting forces and vibration risk; smaller radii suit finishing, fine detail and slender setups.
- ▸Match clearance to the holder. Positive-clearance codes (B/C/P…) require the matching positive toolholder; 0° N inserts seat on negative holders and offer twice the edges.
- ▸Tolerance class for the job. G and tighter classes suit precision and finishing; M-class moulded inserts are the economical default for general turning.
- ▸Pick the chipbreaker for your feed band. Roughing and finishing geometries are not interchangeable in practice even when the core code is identical.
- ▸Toughness vs wear resistance. Tough grades resist interrupted cuts and scale; hard, wear-resistant grades suit stable, high-speed finishing — choose within the same ISO 513 group.
