CNMG120404 T5115 – ISO turning insert for external and internal turning, Tungaloy

The CNMG120404 T5115 is an ISO‑standard rhombic turning insert designed for general‑purpose external and internal turning, featuring a cylindrical hole for secure clamping and a robust CVD‑coated carbide grade.

• CVD‑coated carbide grade T5115
• Rhombic CNMG shape, 80° cutting angle
• 0.4 mm corner radius for precision finishing
• Double‑sided chipbreaker with cylindrical hole

High productivity through a balanced carbide grade

The CVD‑coated T5115 carbide combines wear resistance and cutting‑edge stability, providing a reliable compromise between lifetime and edge strength when machining cast iron. As a universal grade, it supports a wide range of cast‑iron alloys and stabilises chip formation under varying cutting conditions. The result is fewer tool changes and predictable tool behaviour, which contributes directly to improved machining throughput and lower per‑part tooling costs.

Precise geometry for consistent surface quality

With its rhombic CNMG form and an 80° cutting angle, the insert delivers stable engagement and repeatable cutting forces for both external and internal turning. The 0.4 mm corner radius improves surface finish while still allowing controlled material removal; the double‑sided chipbreaker supports efficient chip control across moderate feeds. The cylindrical hole ensures secure clamping in ISO‑standard holders, reducing vibration and helping to maintain a consistent finish on the workpiece.

Process security and practical handling in the workshop

The insert’s ISO conformity simplifies tool selection and replacement within established tool systems, so holders and clamping sets can be chosen according to form, relief angle and tolerance class. The indexable design means two cutting edges per side are available, enhancing cost efficiency by extending usable life before replacement. For production environments seeking stable, repeatable turning of cast iron, this solution supports reduced downtime and easier inventory management while maintaining machining accuracy.

FAQ

What materials is this insert suitable for?
The CNMG120404 T5115 insert is formulated as a universal grade for machining cast iron, offering a balanced combination of wear resistance and edge stability for a wide range of cast‑iron alloys.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius provides a good compromise between strength and finish; it helps produce smoother surfaces while preserving adequate edge robustness for general turning tasks.

Is the insert compatible with standard ISO holders?
Yes, the CNMG120404 follows ISO form and dimensions; compatibility with a specific holder is determined by form, relief angle, tolerance class, clamping method, size and thickness.

What coating technology is used on this grade?
The cutting material is a CVD‑coated carbide grade (T5115), which enhances wear resistance and contributes to consistent performance in cast‑iron turning.

How many usable edges are available on the insert?
The rhombic, double‑sided design offers multiple indexed edges per insert, enabling economical use through rotation and reindexing before replacement.
