CNMG 090402 T6215 Tungaloy turning insert — ISO rhombic, 80° geometry for turning

A CNMG090402 T6215 indexable insert designed for external and internal turning, offering wear-resistant CVD-coated carbide for stable to lightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• ISO rhombic CNMG 09, 80° geometry
• 0.2 mm nose radius for improved surface finish
• Cylindrical hole and double-sided chipbreaker

Maximum process stability through advanced coating and grade

The CVD-coated carbide composition of this insert delivers consistent wear resistance and prolonged edge life under standard and slightly interrupted cuts, which reduces changeover frequency and tool inventory. The T6215 grade is tailored for turning stainless steels where adhesion and built-up edge are common concerns; the coating limits surface diffusion and abrasive wear. In practical terms, this means fewer rejects and longer uninterrupted machining cycles, supporting a predictable production cadence and lower unit cost over time.

Precise geometry for secure clamping and fine surface quality

The ISO CNMG rhombic form with an 80° cutting angle and a 0.2 mm nose radius enables a balance between robustness and surface finish. The cylindrical hole provides reliable mechanical location in compatible holders, while the double-sided chipbreaker permits indexing to a fresh edge and maintains controlled chip formation. For users less familiar with tooling language: an indexable insert such as this is designed to be clamped into a matching holder; the specified form, clearance and thickness determine compatibility and performance, so matching holder geometry and tolerance class is essential for achieving the stated benefits.

Designed for efficient turning workflows and flexible applications

Configured for conventional turning tasks, the insert supports both external and internal operations when combined with the appropriate holder and clamping set. The double-sided design effectively halves tooling cost per usable edge compared with single-sided alternatives, while the CVD coating and substrate combination ensure stable edge life in repetitive production runs. Choosing the right chipbreaker and grade for the workpiece material and machining stability will result in predictable surface quality and fewer tool-indexing events, helping to keep cycle times tight and throughput high.

FAQ

Is this insert suitable for stainless steel machining?
Yes. The T6215 CVD-coated grade in this CNMG090402 insert is formulated for turning stainless steels under stable to lightly interrupted conditions, providing improved wear resistance and surface quality.

How does the CNMG 09 geometry affect holder selection?
Holder compatibility depends on the insert form, clearance, tolerance class, fastening method, size and thickness; the CNMG 09 rhombic geometry and 80° angle require a matching ISO CNMG external or internal holder.

Can the insert be indexed to use both cutting edges?
Yes. This is a double-sided indexable insert with a cylindrical hole and a double-sided chipbreaker, allowing rotation to a fresh edge to extend tool life and reduce tooling cost per edge.

What surface finish can be expected with a 0.2 mm nose radius?
A 0.2 mm nose radius supports finer surface finishes and lower cutting forces compared with larger radii, making it suitable for operations where improved part appearance and tighter tolerances are desired.

Which components are required for a complete turning setup with this insert?
A complete system includes the ISO indexable insert, a compatible external or internal holder or boring bar, a backing/locking set and replacement screws; correct holder matching ensures repeatable positioning and cutting performance.
