CNMG090412 T515 indexable insert for turning by Tungaloy

CNMG090412 T515 is an ISO‑standard indexable insert optimised for economical machining of cast iron in external and internal turning applications

• CVD‑coated carbide T515 for cast iron
• Optimised chip formation for stable cutting
• 80° rhombic geometry for versatile profiling
• 1.2 mm corner radius for durable edges
• Double‑sided insert with cylindrical hole

High economy through optimised carbide and coating

The CNMG090412 T515 insert combines a CVD coating with a robust carbide substrate to deliver consistent performance when machining cast iron. The T515 grade is selected for economical cutting: it promotes stable chip formation and reduces wear rates under typical interrupted and continuous cuts. For production environments seeking lower tooling cost per component, the combination of a wear‑resistant surface treatment and a resilient substrate translates into longer effective tool life and fewer indexings. The result is a tangible efficiency gain without sacrificing workpiece quality.

Geometry that ensures repeatable accuracy and holder compatibility

The insert’s 80° rhombic geometry and 0° clearance angle provide a secure seating position and good access for profiling and facing operations, while the 1.2 mm corner radius balances edge strength with achievable surface finish. The cylindrical hole enables firm clamping in compatible ISO holders; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness. In practice, this means straightforward retrofitting into standard external holders or boring bars, with predictable runout and repeatability for batch production.

Productivity gains from a double‑sided design and robust thickness

A double‑sided construction and a plate thickness of 4.76 mm allow two usable cutting edges per index, lowering cost per edge and simplifying inventory management. The size 09 form factor offers a compact footprint suitable for medium‑duty turning where stiffness and access are required. Together, these features support higher uptime: fewer tool changes, reliable edge geometry and consistent surface quality during longer production cycles.

System integration and practical selection guidance

The insert is supplied as part of an ISO‑based system that includes the insert, a matching external holder or boring bar, and the required clamp set and spare screws. Selection of the correct chipbreaker and grade should be made according to workpiece stability, machining type and desired cutting speed; the T515 grade is especially suited to cast‑iron tasks where stable chips and economical tool life are priorities. For shops consolidating tooling families, the standardised format simplifies procurement and reduces the need for specialised holders.
