CNMG 090402 T6215 Turning insert — Tungaloy

The CNMG090402 T6215 is an ISO‑standard rhombic turning insert designed for external and internal turning, optimised for machining stainless steels under stable to slightly interrupted cutting conditions.

• CVD-coated carbide for high wear resistance
• Rhombic 80° geometry with 0° clearance angle
• 0.2 mm corner radius for robust cutting edges
• Cylindrical hole, ISO-compatible mounting

Consistent chip control for stainless steel turning

The CVD‑coated carbide substrate delivers reliable wear resistance when machining stainless steels, reducing flank wear and maintaining dimensional stability over longer runs. The insert’s double‑sided chipbreaker is engineered to control swarf formation under steady cutting conditions, which leads to more predictable cycle times and fewer interruptions. This precision behaviour supports improved process stability and fewer component reworks, particularly in serial production.

Geometry and mounting for secure, repeatable performance

An 80° rhombic geometry combined with a 0° clearance angle provides a balanced cutting profile that supports both external and internal operations, while the cylindrical hole enables secure fastening in ISO‑compatible holders. The 0.2 mm corner radius increases edge strength without compromising the ability to achieve close tolerances, resulting in reproducible surface finishes and reduced risk of chipping during medium‑duty turning tasks.

Substrate and coating engineered for longer tool life

The toolgrade T6215 is a CVD‑coated carbide grade formulated for wear resistance in corrosive and adhesive materials typical of stainless steels. The coating reduces adhesion tendencies and heat‑related wear, extending the interval between indexings. For manufacturers seeking economical throughput, this combination of substrate and coating contributes to lower tool consumption and consistent part quality over extended production runs.

Practical application guidance to improve process outcomes

Use the insert in stable setups with appropriate rigidity to exploit its chip control and coating properties; select the chipbreaker and grade when matching material, cut depth and machine stability. The ISO‑standard form ensures compatibility with a broad range of holders, simplifying inventory management and enabling quick changeovers between part families. For interrupted cuts, verify clamping and feed settings to maintain edge life and consistent surface integrity.

FAQ

What materials is this insert suitable for?
The Tungaloy CNMG090402 T6215 insert is specified for machining stainless steels, with the CVD coating and substrate tailored to resist adhesive wear common in these alloys.

Is the insert compatible with standard ISO holders?
Yes, the rhombic CNMG090402 form and cylindrical hole comply with ISO standards and fit matching ISO toolholders when the holder geometry and tolerances match.

How does the T6215 grade affect tool life?
The T6215 CVD‑coated carbide offers enhanced wear resistance and heat tolerance, which typically extends tool life and reduces flank wear in steady turning operations.

Can this insert be used for interrupted cuts?
The insert is designed for stable to slightly interrupted conditions; for severe interruptions, review setup rigidity and cutting parameters before use to avoid premature edge chipping.

What are the key geometric features to consider when specifying a holder?
Consider the 80° rhombic geometry, 0° clearance angle, 0.2 mm corner radius and the plate thickness (4.76 mm) to ensure correct fit and clamping in the chosen holder.
