CNMG 120408 T5115 CNMG turning insert for turning by Tungaloy

The CNMG120408 T5115 is an ISO‑standard rhombic turning insert designed for external and internal turning, optimised for cast iron machining.

• CVD-coated carbide grade T5115
• Rhombic CNMG 120408 geometry
• Double-sided chipbreaker, cylindrical hole
• Optimised for cast iron machining

Consistent cutting performance for cast iron

The combination of CVD‑coated carbide and the T5115 grade delivers a reliable balance between wear resistance and cutting edge stability, especially in cast iron applications. The CVD coating reduces flank wear and extends effective cutting life, while the substrate carbide maintains toughness under interrupted cuts. For production environments where process stability matters, this insert offers reproducible performance and reduced tool change frequency, helping to maintain cycle times and surface finish consistency.

Geometry and ISO compatibility that save set‑up time

The CNMG 120408 rhombic shape with an 80° lead angle provides a versatile cutting geometry suited to both external and internal turning. The insert is ISO‑standard, so compatibility with holders is determined by form, relief angle, tolerance class, fastening, size and thickness, enabling straightforward interchangeability in established toolholders. The 0° clearance characteristic and the central cylindrical hole ensure secure seating and reliable clamping, which reduces the need for repeated re‑adjustment and supports steady cutting conditions.

Robust edge control and predictable tool life

With a 0.8 mm corner radius and an insert thickness of 4.76 mm, the design prioritises edge strength and resistance to chipping during moderate to heavy cuts. The double‑sided chipbreaker improves chip control and evacuation in common cast iron grades, reducing the risk of built‑up edge and enhancing surface quality. Together, these features yield a cost‑effective, repeatable tool life that supports higher machine utilisation and consistent component quality.

FAQ

What material is the CNMG120408 T5115 intended for?
The CNMG120408 T5115 is formulated as a universal grade optimised for cast iron, providing balanced wear resistance and edge stability for reliable turning results.

Which holder compatibility aspects must be checked?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, insert size and thickness; the ISO‑standard geometry of this insert simplifies selection for compatible external and internal turning holders.

How does the CVD coating benefit tool life?
The CVD coating on the carbide substrate reduces abrasive wear and improves flank wear resistance, which extends effective cutting life and supports consistent surface finish in serial production.

Is the insert single or double sided?
This insert features a double‑sided chipbreaker, allowing both faces to be used and extending the usable life per insert.
