CNMG160612 T515 insert for turning — Tungaloy

The CNMG160612 T515 is an ISO‑standard rhombic, CVD‑coated carbide turning insert designed for economical and productive machining of cast iron in external and internal turning applications

• ISO rhombic insert CNMG 160612
• CVD‑coated carbide T515 for cast iron
• Double‑sided chipbreaker, cylindrical hole
• 80° cutting angle, 1.2 mm corner radius

Consistent chip control for cast‑iron production

The combination of a double‑sided chipbreaker and the T515 CVD‑coated carbide grade provides reliable chip formation and evacuation, which reduces cycle variability and improves process stability during turning of cast iron. The chipbreaker geometry is matched to the insert form and promotes short, controllable chips even under interrupted cuts; this feature lowers the risk of tool nose damage and minimises secondary operations related to swarf handling. Such controlled chip behaviour supports higher effective utilisation of machining centres and enhances overall shop throughput.

Precise fit and simple mounting to existing holders

Designed as an ISO‑standard indexable insert, the rhombic shape with a cylindrical hole and standard fixation details makes the component compatible with a wide range of ISO holders and boring bars when the holder’s form, relief angle, tolerance class, fastening method, size and thickness match. The insert’s geometry and the 80° cutting angle result in a good compromise between radial strength and access to workpiece features, while the 1.2 mm corner radius increases edge robustness for medium‑depth cuts. Clear compatibility criteria help planning and reduce setup times in production environments.

Coating and grade explained for dependable tool life

The CVD‑coated carbide substrate offers a wear‑resistant surface that stands up to the abrasive nature of many cast‑iron grades. The T515 grade is tuned for economical machining: it balances tool life, stable flank wear progression and acceptable edge strength so that longer tool life is achievable without sacrificing productivity. For users less familiar with coating technology, CVD (chemical vapour deposition) produces a uniform, adherent coating that improves heat resistance and reduces adhesive wear, which translates into more predictable replacement intervals and less unplanned downtime.

Productivity benefits for job shops and production lines

Using an indexable insert with clearly defined specifications — CNMG160612, 6.35 mm plate thickness and standard ISO sizing — simplifies inventory management and reduces the need for frequent regrinds or special tooling. The rhombic form and the chosen corner radius make the insert versatile across facing, profiling and medium roughing tasks; this versatility supports faster setup changes and fewer tool types per machine. In short, the insert helps maintain a steady machining flow, reduces handling complexity and contributes to repeatable component quality.

FAQ

Is this insert suitable for cast‑iron machining?
Yes. The CNMG160612 T515 insert is specified for economical machining of cast iron; the T515 grade and CVD coating support stable chip formation and wear resistance in such applications.

Which holders fit the CNMG160612 geometry?
Compatibility requires a holder matching the ISO rhombic form, relief angle, tolerance class, fastening and plate thickness; selecting a matching ISO holder ensures secure clamping of the CNMG160612 insert.

Can the insert be used for internal turning as well as external turning?
Yes. The insert’s rhombic form and 80° cutting angle make it suitable for both external and internal turning tasks, provided an appropriate boring bar or internal holder is used.

What does the double‑sided chipbreaker mean in practice?
A double‑sided chipbreaker provides chip control on both usable faces of the insert, allowing rotation to a fresh edge and extending the effective service life compared with single‑sided variants.

What are the key dimensions to check before purchase?
Check the insert designation (CNMG160612), plate size (16 mm), plate thickness (6.35 mm), corner radius (1.2 mm) and whether the holder accepts a cylindrical hole for proper fixation.
