CNMG120404 T5115 CNMG turning insert by Tungaloy — CVD-coated carbide, double-sided

CNMG120404 T5115 is an ISO‑format turning indexable insert designed for external and internal turning of cast iron, offering balanced wear resistance and stable cutting edges

• ISO CNMG120404 geometry, rhombic form
• CVD-coated carbide grade T5115 for cast iron
• Double-sided insert with 0.4 mm nose radius
• Cylindrical hole for repeatable seating and clamping

Faster, more consistent machining of cast iron

The CVD-coated carbide grade T5115 provides a balanced combination of wear resistance and edge stability, which supports productive cutting when turning cast iron. As a universal grade, it is formulated to handle varying chip loads while maintaining surface quality; the double-sided chipbreaker promotes consistent chip control, reducing interruptions and lowering rework risk. Selection of the matching chipbreaker and insert geometry ensures predictable cycle times and a smoother process flow.

Reliable fit and stable cutting conditions

The ISO CNMG geometry with a rhombic shape and an included 80° approach lends itself to versatile toolholder compatibility. The insert’s cylindrical hole and standardised dimensions allow it to be seated and clamped with repeatable accuracy; compatibility depends on the holder’s form, clearance angle, tolerance class, fastening method, size and thickness. With a 0° relief and a compact profile, the plate is suited to both external and internal turning stations where rigid clamping and minimal overhang are priorities.

Lower operating costs through efficient tool use

A double‑sided design reduces the cost per cutting edge and simplifies inventory management, while the 0.4 mm nose radius supports fine surface finishes without sacrificing edge strength. Controlled chip formation from the integrated chipbreaker minimises built‑up edge and facilitates coolant escape, improving tool life and part consistency. When combined with an appropriate holder and correct cutting parameters, predictable wear behaviour and longer intervals between indexings can be achieved.

FAQ

Which materials is this insert suited for?
The CNMG120404 T5115 insert is a universal grade primarily intended for machining cast iron, offering a balanced compromise between wear resistance and edge stability for reliable performance.

Can the indexable plate be used for both internal and external turning?
Yes, the CNMG120404 geometry and the 0° relief make the insert suitable for external and internal turning operations when paired with an appropriate ISO holder.

How does the chipbreaker affect machining results?
The double‑sided chipbreaker on this insert promotes consistent chip formation and evacuation, improving surface finish and reducing the likelihood of built‑up edge during cast‑iron turning.

What ensures secure clamping and repeatable seating?
The cylindrical hole combined with standardised dimensions allows repeatable seating; compatibility and secure fixation are achieved when the holder matches the insert’s form, tolerance and thickness.

Is this insert reversible and economical to use?
The double‑sided design provides multiple usable edges, lowering cost per edge and simplifying tool rotation strategies for extended service life.
