CNMG120404 T6215 ISO turning insert — 80° rhombic, Tungaloy

A CNMG120404 T6215 indexable turning insert designed for external and internal turning of stainless steels, offering CVD-coated carbide performance and reliable chip control in stable to lightly interrupted operations.

• CNMG120404 ISO turning insert T6215
• CVD-coated carbide for stainless steel
• 80° rhombic geometry, 0° clearance angle
• Double-sided insert with cylindrical hole

High-performance coating for stainless-steel turning

The CVD-coated carbide grade T6215 provides a wear-resistant surface that extends tool life when machining stainless steel under steady or lightly interrupted cuts. The coating improves thermal and chemical stability at the cutting edge, which reduces flank wear and maintains dimensional accuracy over longer tool cycles. As a result, cycle times and rework can be reduced, contributing to predictable production throughput and lower per-part machining cost.

Geometry and dimensions that combine strength with surface finish

An 80° rhombic geometry paired with a 0° clearance angle and a corner radius 0.4 mm delivers a balance between rigidity and surface quality. The nominal plate size of 12 mm and a plate thickness of 4.76 mm provide mechanical support for heavier cuts while the small corner radius helps to achieve a consistent surface finish on external and internal profiles. The insert’s double-sided design further increases usable cutting edges, improving cost efficiency in serial machining.

System compatibility and operational benefits in the workshop

The insert conforms to ISO plate standards, so compatibility with external holders or boring bars depends on form, clearance angle, tolerance class, fastening and plate thickness. The cylindrical hole facilitates secure clamping in a wide range of ISO CNMG toolholders, and the double-sided chipbreaker enhances chip control across common stainless-steel grades. Integrating this insert into the tool system streamlines tool inventory and reduces changeover times, supporting a smoother production flow with predictable results.

FAQ

What materials is this insert suitable for?
The CNMG120404 T6215 insert is designed primarily for stainless steel turning; the T6215 CVD-coated carbide provides wear resistance for stable to lightly interrupted cutting conditions.

Which toolholders are compatible with this ISO insert?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the ISO CNMG geometry fits standard CNMG external holders and boring bars when those parameters match.

Is the insert single- or double-sided and how does that affect economy?
This is a double-sided insert with a double-sided chipbreaker, offering multiple cutting edges per plate and reducing tooling cost per edge compared with single-sided alternatives.

What are the key dimensions to check before selecting a holder?
Check plate size (12 mm), thickness (4.76 mm), corner radius (0.4 mm), included angle (80°) and the 0° clearance angle to ensure correct fit and performance.

Can this insert be used for both external and internal turning?
Yes — the ISO CNMG form and chipbreaker design make it suitable for both external and internal turning when assembled in the correct holder and under suitable cutting conditions.
