CNMG 120402 T6215 indexable insert for turning — Tungaloy, CVD-coated, 0.2 mm radius

The CNMG120402 T6215 indexable insert for turning provides a wear-resistant, CVD-coated solution optimised for stainless-steel applications under steady to lightly interrupted cuts

• CVD-coated carbide grade T6215
• ISO CNMG 120402 rhombic insert
• 0.2 mm nose radius for fine finishes
• Double-sided chipbreaker, cylindrical hole

Consistent performance for stainless-steel turning

The CVD-coated cemented carbide matrix of this insert offers high wear resistance specifically designed for machining stainless steel under stable to slightly interrupted conditions. The T6215 grade balances edge stability and toughness, which reduces flank wear and helps maintain dimensional accuracy across longer tool life. In practice, this means fewer tool changes and more predictable component quality — a direct contribution to improved cycle-time efficiency and reduced scrap rates in serial production.

Geometry and compatibility that simplify set-up

The rhombic CNMG geometry with an 80° lead angle and a 0° relief provides a versatile cutting edge suited for both external and internal turning operations. The insert’s 0.2 mm nose radius supports fine surface finishes while the 4.76 mm thickness and 12 mm size ensure mechanical stability in standard ISO toolholders. Compatibility with a holder depends on form, relief angle, tolerance class, mounting method, size and thickness; selecting the correct holder and clamping kit is essential for achieving the intended performance and repeatability in the machining process.

Practical benefits for production and process security

With a double-sided chipbreaker and a cylindrical hole for secure fastening, the insert promotes stable chip formation and reliable clamping under load. The design aims to reduce vibrations and maintain a stable cutting edge during continuous runs, which supports consistent surface quality and extended insert life. For workshop planners, this results in lower downtime and more predictable maintenance intervals, contributing to overall process security and cost-efficiency in turning operations.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The CNMG120402 T6215 insert features a CVD-coated cemented carbide grade developed for stainless-steel turning under stable to lightly interrupted conditions.

What chip control does the insert provide?
The insert is supplied with a double-sided chipbreaker, designed to promote stable chip formation and reduce the risk of troublesome swarf in turning operations.

How does one ensure compatibility with a toolholder?
Compatibility is determined by insert form, relief angle, tolerance class, mounting method, size and thickness; verifying these parameters against the chosen toolholder ensures correct seating and clamping.

Does the insert have a central hole and what is its style?
Yes. The insert is provided with a cylindrical hole to suit standard clamping and fastening arrangements in compatible holders.

What are the key geometry values to consider for set-up?
Important measurable values include the 80° lead angle, 0.2 mm nose radius, 4.76 mm thickness and 12 mm size, which together influence cutting forces, finish and mechanical stability.
