CNMG120404 T6215 CNMG Turning Insert for Turning – Tungaloy, CVD‑coated carbide, 0.4 mm radius

CNMG120404 T6215 is an ISO‑standard rhombic turning insert engineered for external and internal turning of stainless steels under stable to slightly interrupted conditions.

• CVD‑coated carbide for wear resistance
• Rhombic CNMG shape, 80° cutting angle
• 0.4 mm corner radius for edge strength
• Double‑sided chipbreaker with centre hole

Durable grade for stainless‑steel applications

The insert is manufactured in a CVD‑coated carbide grade (T6215) that enhances resistance to abrasive wear and built‑up edge when machining stainless steel. The coating reduces adhesion of workpiece material and supports longer tool life under continuous production. This results in fewer indexings and more consistent component dimensions, which is particularly relevant for shops aiming at reproducible quality and reduced downtime.

Geometry that balances strength and versatility

The CNMG rhombic outline with an 80° included angle and a 0.4 mm corner radius provides a stable cutting edge suited to a wide range of turning tasks. The double‑sided chipbreaker and central hole enable secure clamping and bidirectional use, optimising economy per insert. Descriptors such as insert thickness 4.76 mm and size 12 mm contribute to mechanical stability, which helps in maintaining form tolerances on medium‑section components.

Practical system compatibility and setup guidance

As an ISO‑standard turning insert, compatibility depends on holder form, clearance angle, tolerance class, clamping method and insert size; selecting the matching toolholder or boring bar is essential. The 0° clearance setting and cylindrical centre hole require appropriate seat geometry and a correct clamping screw; choosing a chipbreaker and grade that match workpiece stability and feed conditions will improve chip control and surface finish. For less experienced staff, the combination of T6215 grade and the rhombic geometry gives a robust starting point for general stainless‑steel turning.

FAQ

What materials is this insert suitable for?
The Tungaloy CNMG120404 T6215 insert is designed primarily for stainless steel and performs best under stable to lightly interrupted turning conditions.

Is the insert reversible and how is clamping achieved?
The insert is double‑sided and reversible; clamping is achieved via the central cylindrical hole and the matching clamp/screw in the toolholder.

Which chipbreaker should be chosen for roughing or finishing?
Select the chipbreaker variant that matches the intended operation: the supplied double‑sided chipbreaker offers versatility, but choosing a coarser breaker for roughing and a finer profile for finishing improves chip control and surface quality.

How does the T6215 grade influence tool life?
The T6215 CVD‑coated grade provides improved wear resistance and reduced adhesion on stainless steel, which typically extends tool life and maintains consistent cutting performance.

Can this insert be used in interrupted cuts?
Yes; the insert is suitable for stable to slightly interrupted cuts, but heavily interrupted machining may require a different geometry or special grade for optimal performance.
