CNMG 120404 T6215 – Turning insert (ISO CNMG120404) by Tungaloy

CNMG120404 T6215 Tungaloy insert is a rhombic ISO turning insert designed for secure mounting and robust performance in medium to stable cutting conditions.

• CVD-coated carbide grade T6215
• Optimised for turning rostfreier Stahl
• Rhombic CNMG120404, 80° cutting geometry
• Double-sided chipbreaker for stable chips

Longer edge life for rostfreier Stahl turning

The combination of a CVD-coated carbide base and the T6215 wear-resistant grade provides a measurable increase in lifetime under continuous and slightly interrupted cuts. The coating reduces flank and crater wear, which translates into fewer indexings and longer production runs. With this specification, the insert is particularly suited where consistent component quality and reduced tool handling improve throughput.

Predictable fit and straightforward interchangeability

Built to the ISO CNMG120404 standard, the insert’s 80° rhombic geometry and defined thickness ensure compatibility with a wide range of external holders and boring bars when the holder matches form, relief angle, tolerance class, fixing method, size and thickness. This predictability shortens set-up time and reduces the risk of incorrect seating, delivering repeatable positioning and consistent cutting performance in serial production.

Improved productivity through chip control and stability

The double-sided chipbreaker and the cylindrical hole secure a firm clamp and effective chip formation, reducing vibration and improving surface finish. Better chip control also lowers the chance of built-up edge and minimizes rework. In practice, these features support higher material removal rates and stable machining of rostfreier Stahl while maintaining dimensional accuracy.

Where this insert performs best and how to apply it

Designed for external and internal turning operations, the indexable plate performs well in workshops seeking balanced productivity and tool life. Select the T6215 grade and the appropriate chipbreaker depending on workpiece rigidity and cutting mode; a more stable set-up often allows more aggressive feeds while preserving surface quality. For tailored cutting parameters and holder recommendations, technical consultation is advised to match insert choice to the specific turning task.

FAQ

Which materials is this insert suitable for?
The CNMG120404 T6215 insert is optimised for rostfreier Stahl and offers high wear resistance when machining this material.

Can the insert handle interrupted cuts?
Yes, the T6215 grade is designed to tolerate stable to slightly interrupted cutting conditions; more severe interruptions may require specific grades or edge preparations.

What determines compatibility with a toolholder?
Compatibility depends on form, relief angle, tolerance class, fixing method, size and thickness; the ISO CNMG120404 format ensures wide holder availability.

What surface finish can be expected with this geometry?
The 80° rhombic geometry combined with the double-sided chipbreaker promotes controlled chip formation and consistent surface quality when the cutting data match workpiece rigidity.

How is the insert secured in the holder?
The plate uses a cylindrical central hole for positive locating and is clamped with the appropriate screw and clamp system specified by the holder manufacturer.
