CNMG120404 T515 ISO turning insert — CVD‑coated carbide for cast iron, 0.4 mm radius (Tungaloy)

The CNMG120404 T515 indexable insert is an ISO‑standard rhombic insert designed for external and internal turning, combining a stable geometry with a CVD‑coated hard metal grade for economic cast iron machining.

• ISO‑standard CNMG120404 geometry
• CVD‑coated carbide grade T515
• Optimised for cast iron machining
• Double-sided chipbreaker, 0.4 mm radius

Consistent productivity for cast iron components

The CVD‑coated T515 grade delivers enhanced surface endurance and stable chip formation, which together reduce the frequency of tool changes and interruptions. The coating provides a thin, wear‑resistant layer that protects the substrate during high contact temperatures; this translates into predictable tool life and improved productivity in long production runs. Selection of the correct chipbreaker and grade is recommended for machining stability and the desired feed and cutting speed combination.

Interchangeable geometry for secure clamping and repeatability

Designed as an ISO‑conforming insert, the rhombic CNMG shape with an 80° lead angle and 0° clearance ensures compatibility with common external holders. The standardised dimensions — 12 mm inscribed circle and 4.76 mm thickness — simplify tool inventory and holder matching. A cylindrical hole and tolerance class determine secure retention; consistent fit reduces vibration and supports repeatable part tolerances, making setup times shorter and process behaviour more predictable.

Process security and economical operation

The double-sided chipbreaker enables two effective cutting edges per indexation, increasing usable life and lowering cost per part. The substrate of carbide combined with the CVD coating offers resistance against abrasive wear typical of cast iron workpieces, while the 0.4 mm corner radius balances edge strength with surface finish. For interrupted cuts or variable stability conditions, the choice of chipbreaker and grade prioritises both tool life and component quality. Integration into a system of insert, holder, clamping set and spare screws supports efficient tool management.
