CNMG120412 T515 Tungaloy insert for Turning — rhombic ISO‑form, CVD‑coated carbide

CNMG120412 T515 Tungaloy-Wendeplatte is an ISO‑standard indexable turning insert designed for efficient external and internal turning of cast iron and similar materials

• CVD‑coated carbide for cast iron machining
• ISO CNMG form with 80° geometry
• Double‑sided chipbreaker for stable cutting
• Rhombic insert, 1.2 mm nose radius

Efficient cast‑iron turning through optimised grade and geometry

The combination of a CVD‑coated carbide substrate and the T515 grade provides a balance of wear resistance and toughness that suits economical machining of cast iron. The coating reduces flank wear at elevated temperatures, which translates into longer effective tool life and more consistent component quality. Engineers benefit from predictable tool behaviour: selecting this insert reduces machine idle time and supports higher material removal rates where the workpiece and setup stability allow. This paragraph focuses on measurable performance advantages and directly supports decision‑making for production planning.

Stable chip control and dimensional reliability for turning operations

With the CNMG rhombic outline and an 80° approach angle, the insert delivers a favourable combination of cutting edge strength and accessibility for shoulder and facing cuts. The double‑sided chipbreaker promotes regular chip formation, which lowers the risk of built‑up edge and improves surface finish in interrupted and continuous cuts. The 1.2 mm nose radius contributes to dimensional stability while allowing finish passes without excessive tool deflection. This section explains how geometry and chip control translate into consistent part tolerances and reduced rework.

Practical compatibility and selection guidance for workshop integration

Compatibility with standard toolholders is governed by the insert form, relief angle, tolerance class, mounting method, size and thickness; the ISO designation ensures interchangeability across established toolholder systems. The insert comes with a cylindrical locating hole and a thickness of 4.76 mm, making it suitable for typical CNMG clamping systems. When integrating the insert into an existing tooling inventory, consider machine rigidity and cutting conditions to match the T515 grade to the chosen cutting speed and feed. This paragraph provides clear, actionable guidance for procurement and setup.

FAQ

What materials is this insert suitable for?
The insert is intended primarily for the economic machining of cast iron; the T515 CVD‑coated carbide grade is selected to balance wear resistance and toughness for such materials.

How does the CNMG geometry affect machining?
The rhombic CNMG shape with an 80° approach angle gives a robust cutting edge for shoulder and general turning work while offering good access for internal and external operations.

Is the insert reversible?
Yes, the insert is double‑sided with a chipbreaker on both sides, allowing indexable reversal to extend tool life and reduce tooling costs.

Which toolholder features must be checked for compatibility?
Compatibility depends on insert form, relief angle, tolerance class, mounting method, size and thickness; use ISO‑compliant holders sized for CNMG120412 inserts.

How does the T515 grade influence cutting parameters?
The T515 grade supports productive cutting speeds in cast iron while offering stable edge life; adjust speeds conservatively for interrupted cuts and increase where setup rigidity permits.
