• Designed for heat-resistant alloy machining
• Rhombic CNMG 80° geometry, 1.6 mm corner radius
• Double-sided insert with cylindrical hole

High productivity through a balanced carbide grade

The PVD-coated cemented carbide grade AH8015 delivers a deliberate compromise between wear resistance and edge stability, making it suitable for a wide range of operations on heat-resistant alloys. The coating enhances surface hardness and reduces built-up edge, resulting in more consistent tool life and fewer interruptions for insert changes. For production-focused environments, this combination supports predictable cycle times and reduces overall tooling consumption, improving cost-efficiency per part without sacrificing finish quality.

Reliable fit and straightforward integration into ISO systems

Based on the ISO CNMG format, the insert ensures compatibility with standard toolholders when the holder’s form, free angle, tolerance class, clamping method, size and thickness match. The rhombic geometry with an 80° included angle and a 0° clearance angle provides a clear definition of where the insert will engage the workpiece, while the cylindrical hole ensures secure clamping and repeatable seating. These attributes simplify inventory management and speed up tool changes in mixed-production settings by relying on established ISO standards.

Stable cutting performance and surface quality

The double-sided design and 1.6 mm corner radius give strength at the cutting edge, which improves resistance to impact and edge chipping during interrupted cuts or unstable setups. A plate thickness of 4.76 mm contributes to rigidity and dampens vibration, aiding in attaining consistent surface finishes during both external and internal turning. The integrated chipbreaker geometry supports manageable chip formation on materials that tend to produce stringy or serrated chips, lowering the risk of workpiece damage and enhancing operator safety.

Application guidance for process optimisation

Select the double-sided chipbreaker and the grade AH8015 when machining heat-resistant alloys under medium to high cutting parameters or when stability is moderate to good. For less rigid setups, reduce feed or opt for a smaller corner radius to avoid excessive cutting forces. The PVD coating performs particularly well where thermal stability at the edge matters; however, correct holder rigidity and mounting are equally important to achieve repeatable results. If additional process data is required, Metav Werkzeuge provides technical guidance to match insert selection with machine capability and workpiece material.

FAQ

What materials is this insert intended for?
This insert in grade AH8015 is intended primarily for machining heat-resistant alloys and other demanding materials where a balance of wear resistance and edge stability is required.

Which insert geometry and size does the CNMG120416 describe?
CNMG120416 denotes a rhombic CNMG insert with an 80° included angle, a 1.6 mm corner radius and a plate thickness of 4.76 mm, suitable for ISO-compatible holders.

Is the insert single- or double-sided and how does that affect use?
The insert is double-sided, allowing indexation to the second cutting edge; this extends useful life and reduces replacement frequency under appropriate cutting conditions.

What role does the PVD coating play for this insert?
The PVD coating increases surface hardness and thermal resistance at the cutting edge, improving wear behaviour and reducing built-up edge during turning of heat-resistant alloys.

How should the insert be mounted for best repeatability?
For repeatable performance, mount the ISO CNMG insert into a matching holder that fits form, tolerance, clamping style, size and thickness; the cylindrical hole aids secure seating and correct alignment.
