CNMG 090408 T6215 – Indexable insert for turning by Tungaloy

The CNMG090408 T6215 is an ISO-standard indexable turning insert designed for reliable machining of stainless steels under stable to lightly interrupted cutting conditions

• ISO-standard CNMG shape, 80° cutting angle
• CVD-coated carbide grade T6215 for stainless steel
• Double-sided chipbreaker for consistent chip control
• Rhombic insert with 0.8 mm corner radius

Outstanding wear resistance for turning stainless steel

The CVD-coated carbide grade T6215 provides a durable cutting edge with improved resistance to abrasive and adhesive wear, which is particularly beneficial when machining stainless steel. The chemical and mechanical stability of the coating reduces built-up edge formation and helps maintain consistent surface finish over longer tool life. As a result, material removal rates can remain steady while downtime for tool changes is reduced, supporting efficient production cycles and predictable tool-change intervals.

Stable machining through geometry and chip control

Built as an ISO-standard CNMG insert with a double-sided chipbreaker, the geometry promotes reliable chip formation and evacuation. The cylindrical hole and standard ISO form enable secure clamping and quick indexability on compatible holders, allowing two usable cutting edges per face. These features together translate into reduced vibration, fewer interruptions for regrinding and a more uniform process window for turning operations, which is advantageous in batch production and repeatable series work.

Geometry tuned for precision and flexibility

The rhombic plate form delivers an effective compromise between accessibility and edge strength: the 80° cutting angle supports versatile engagement for both external and internal turning, while the 0.8 mm corner radius helps achieve balanced edge strength and surface quality. With a plate thickness of 4.76 mm, the insert provides stability in the tool pocket and resistance to mechanical distortion under moderate cutting forces. These dimensional features aid in achieving repeatable tolerances and improved surface integrity during finishing and light roughing passes.

Practical guidance for selection and integration

Compatibility with a toolholder depends on insert form, clearance angle (0°), tolerance class, fastening method, size and thickness; matching these parameters ensures correct seat fit and clamping stability. The insert is suitable for applications that demand good surface finish and consistent chip control; for more heavily interrupted cuts a different grade or geometry may be preferable.

FAQ

What materials is this insert best suited for?
The CNMG090408 T6215 insert is intended primarily for machining stainless steel; the CVD-coated carbide grade T6215 improves wear resistance and reduces built-up edge during turning

How does the double-sided chipbreaker benefit production?
A double-sided chipbreaker extends usable edges per insert and ensures consistent chip formation, which maintains process stability and reduces the frequency of insert changes for turning operations

Which holder characteristics must be checked for correct fit?
Ensure the holder matches the ISO CNMG form, the 0° clearance, the plate thickness of 4.76 mm, the plate size and the fastening method; correct fitment secures clamping stability and repeatable performance

Can this insert be used for interrupted cuts?
The T6215 grade is engineered for stable to slightly interrupted cuts; for heavy interruptions alternative grades or geometries may be recommended to improve edge robustness

Is the CNMG090408 T6215 reversible and indexable?
Yes, the rhombic CNMG form with double-sided chipbreaker provides multiple usable cutting edges and enables simple indexing to restore a fresh edge
