CNMG 120412 T515 ISO turning insert — CVD-coated carbide, 80° rhombic — Tungaloy

A CNMG 120412 T515 indexable insert designed for efficient external and internal turning of cast iron, offering reliable chip control and production-ready durability

• ISO rhombic insert CNMG 120412 T515
• CVD-coated carbide for cast iron machining
• Double-sided chipbreaker for reliable chips
• 0° relief, 80° included angle

Consistent material removal and measurable productivity gains

The CVD-coated T515 grade is engineered for the economic machining of cast iron and provides a reliable balance between tool life and cutting performance. The hard, wear-resistant carbide substrate with a chemical vapour deposition coating promotes stable chip formation, which reduces unplanned tool changes and helps to maintain cycle times. In practice this means fewer interruptions in production and a lower cost per finished part when the correct feed and speed parameters are applied.

ISO compatibility for straightforward system integration

Manufactured to the ISO model series for turning inserts, the geometry and tolerances ensure compatibility with matching holders. Compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness; therefore selection of a suitable holder, shim and clamping set is essential for repeatable performance. This standardisation simplifies inventory and ensures fast replacement, which supports continuous production and reduces setup time.

Geometry tailored for robustness and surface quality

The rhombic 80° geometry combined with a 0° relief angle and a 1.2 mm corner radius gives a secure cutting edge for both external and internal turning operations. A 4.76 mm plate thickness and a cylindrical centre hole enable secure, repeatable clamping and straightforward orientation in the seat. The double-sided chipbreaker extends usable life and improves chip evacuation during interrupted cuts, delivering a dependable surface finish without sacrificing process stability.

Process-focused advantages for series production

Designed for series and single-pass operations, the insert supports efficient machining strategies where stable chip control and predictable wear behaviour are required. Selecting the T515 grade according to workpiece stability and intended cutting speed yields an attractive balance between productivity and component quality. The combination of geometry, chipbreaking and coating reduces rework and contributes to a more economical, higher-throughput machining cycle.

FAQ

What materials is the insert best suited for?
The insert in the CNMG 120412 T515 grade is intended primarily for cast-iron machining; the CVD-coated carbide construction supports reliable chip control in grey and compacted graphite iron.

Can this insert be used for interrupted cuts?
Yes, the combination of the rhombic 80° geometry and the double-sided chipbreaker makes the CNMG 120412 T515 suitable for interrupted cuts when the holder and clamping are sufficiently rigid.

How does the coating affect performance?
The CVD coating on the T515 grade increases wear resistance and improves chip control, which together extend tool life and support consistent surface quality over longer runs.

Which holders are compatible with this ISO insert?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; use holders designed for CNMG 120412 inserts and ensure correct shim and clamping to achieve repeatable results.

What is the significance of the 1.2 mm corner radius?
A 1.2 mm corner radius balances edge strength and surface finish, offering robustness for heavier cuts while still allowing acceptable finish levels on turned components.
