CNMG 120404 AH8015 Wendeplatten - Tungaloy

Reliable performance for turning of heat‑resistant alloys is achieved through the combination of a PVD‑coated carbide grade and a precise ISO CNMG120404 geometry, delivering stable cutting edges and consistent chip control; order the CNMG120404 AH8015 indexable insert directly via Metav Werkzeuge or consult our specialists for holder compatibility.

CNMG 120404 AH8015 ISO turning insert — PVD‑coated carbide for turning by Tungaloy

The CNMG120404 AH8015 is an ISO‑standard rhombic indexable insert designed for general turning; it is optimised for machining heat‑resistant alloys with emphasis on edge stability and reproducible performance.

• ISO CNMG120404 geometry, rhombic 80° angle
• PVD‑coated carbide AH8015 for heat‑resistant alloys
• Double‑sided chipbreaker for consistent chip control
• Cylindrical hole for standard clamping compatibility

High process reliability through balanced grade and coating

The combination of a PVD‑coated carbide substrate and the AH8015 grade provides a balance between wear resistance and cutting‑edge stability, making the insert suited to continuous and interrupted turning of demanding materials. The coating reduces adhesion and thermal softening at the cutting zone, which in turn extends usable edge life and maintains component tolerances during longer production runs. This results in predictable tool life and fewer unscheduled tool changes, supporting efficient shopfloor planning.

Compatibility and secure clamping for repeatable accuracy

The insert’s rhombic shape with an 80° lead angle and a cylindrical hole fits common ISO external holders when the holder form, clearance angles, tolerance class, fixation and size are matched. The standardised geometry enables interchangeability between holders from different suppliers, while the defined thickness of 4.76 mm and corner radius 0.4 mm ensure repeatable cutting positions. Where repeatability is required, pairing the insert with the recommended rigid holder and correct clamp torque preserves dimensional stability across batches.

Controlled chips and consistent surface quality

A double‑sided chipbreaker provides reliable chip control for both external and internal turning operations, reducing the risk of entanglement and protecting the workpiece surface. The insert’s edge preparation, together with the PVD layer, contributes to improved surface finish and lower built‑up edge formation when machining high‑temperature alloys. Selecting the appropriate feed and depth of cut for the grade minimises vibration and helps achieve consistent part appearance with reduced secondary finishing.

Practical selection advice for tooling managers and engineers

For general turning tasks in heat‑resistant alloys choose the CNMG120404 AH8015 when a compromise between edge robustness and wear performance is needed. Where higher abrasive resistance or extended life is required, consider complementary grades or coatings; where maximum edge stability is paramount, reduce cutting parameters slightly to protect the cutting edge. The insert forms part of a system: indexable insert, compatible external holder or boring bar, clamping pad and replacement screws—ensuring the full system is specified avoids unexpected fit or tolerance issues.

FAQ

What materials is this insert intended for?

The CNMG120404 AH8015 insert is intended primarily for the turning of heat‑resistant alloys, where the PVD‑coated carbide grade balances wear resistance and edge stability.

Is the insert compatible with standard ISO holders?

Compatibility depends on holder form, clearance, tolerance class and clamping method; the insert’s rhombic ISO CNMG120404 geometry and cylindrical hole are designed for standard external holders when matched correctly.

What is the corner radius and how does it affect machining?

The corner radius is 0.4 mm, which offers a compromise between edge strength and surface finish; a larger radius increases edge robustness while a smaller radius can improve fine surface appearance.

How does the chipbreaker influence production?

The double‑sided chipbreaker provides consistent chip control in a variety of turning operations, reducing chip entanglement and improving process security for longer unmanned cycles.
