CNMG 120404 T5115 — ISO turning insert (rhombic, CVD‑coated carbide) by Tungaloy

The CNMG120404 T5115 is an ISO‑standard rhombic indexable insert engineered for external and internal turning, optimised as a universal grade for cast iron machining.

• CVD‑coated carbide for wear resistance
• Double‑sided chipbreaker for consistent chip control
• Rhombic 80° geometry for versatile turning
• Cylindrical hole for secure clamping

Durable, wear‑resistant grade for dependable productivity

The insert’s CVD‑coated carbide construction and grade T5115 deliver a balanced combination of wear resistance and edge stability, designed specifically for machining cast iron. The CVD coating forms a hard, heat‑resistant layer that reduces flank and crater wear during heavy cuts; this translates into longer tool life and fewer indexings or insert changes. For production environments where tool change frequency impacts throughput, the result is a measurable improvement in process continuity and reduced downtime. The double‑sided chipbreaker further aids repeatable chip formation, supporting consistent surface quality even under varying feed conditions.

Geometry and clamping that ensure predictable surface quality

The rhombic plate shape with an 80° included angle and a 0.4 mm corner radius combines strength at the cutting edge with the option for finer surface finishes. A larger corner radius increases edge robustness for roughing passes, while the specified radius supports a controlled contact zone for finishing. The insert’s 4.76 mm thickness and cylindrical hole enable secure seating in ISO‑compatible holders, improving repeatability and minimising vibration. Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; selecting the correct holder and clamp ensures the mechanical stability required for predictable component tolerances.

System benefits: integration, handling and process guidance

Delivered as part of a classic ISO insert system — insert, appropriate external holder or boring bar, shim/clip and fixing screw — this solution simplifies tool inventory and reduces setup complexity. The reversible, indexable design offers multiple cutting edges per insert, lowering cost per cutting edge and supporting leaner tool logistics. For customers seeking quick integration into existing toolrooms, Metav Werkzeuge can advise on matching holders, clamping sets and replacement screws. The overall effect is improved process reliability and easier standardisation across turning applications.

FAQ

What materials is this insert intended for?
The CNMG120404 T5115 insert is a universal grade optimised for cast iron; the T5115 composition balances wear resistance and edge stability for typical grey and nodular cast‑iron turning tasks.

Is the insert compatible with standard ISO holders?
Compatibility is ISO‑based: form, relief angle (0°), tolerance class, fastening method, size (12 mm) and thickness (4.76 mm) determine fit — choose an ISO‑compatible holder that matches these parameters for secure clamping.

How does the chipbreaker affect machining?
The double‑sided chipbreaker promotes consistent chip formation and evacuation, improving surface finish and reducing the risk of chip‑related interruptions during long turning cycles.

Can both sides of the insert be used?
Yes. The indexable, reversible design and double‑sided chipbreaker allow multiple cutting edges per insert, which reduces tooling costs and extends usable life before replacement.

Where to get holder and cutting‑data recommendations?
For holder selection and cutting‑data tailored to specific machines and cast‑iron grades, Metav Werkzeuge can provide application guidance and compatible clamping solutions.
