CNMG120412 AH8015 — CNMG 120412 AH8015 turning insert, Tungaloy

CNMG120412 AH8015 is an ISO‑standard indexable insert for external and internal turning, optimised for heat‑resistant alloys and general turning tasks

• PVD‑coated carbide grade AH8015
• Rhombic 80° shape with cylindrical hole
• Double-sided chipbreaker for stable cutting
• Corner radius 1.2 mm for medium finish

High‑performance grade for heat‑resistant alloys

The AH8015 grade is a PVD‑coated carbide engineered as a first choice for general machining of heat‑resistant alloys. The coating enhances wear resistance while the substrate retains edge stability, which reduces flank wear under intermittent heat loads. For operations demanding a balance between durability and a reliable cutting edge, this formulation delivers consistent cutting performance and predictable tool life, particularly in finishes where thermal stability is critical.

ISO geometry and assured system compatibility

This insert follows the ISO CNMG120412 designation and a rhombic 80° geometry, making it compatible with standard CNMG holders when form, relief angle, tolerance class, fastening, size and plate thickness match. The cylindrical hole and 4.76 mm plate thickness simplify mechanical clamping, while the 0° relief angle and 80° insert angle influence approach strategy and cutting forces. Specifying the correct holder and clamping set ensures repeatable seating and accurate tool offsets, reducing set‑up time and measuring effort.

Productivity gains through chip control and indexing

Featuring a double‑sided chipbreaker, this insert provides controlled chip formation across a range of feeds, which improves surface finish and reduces risk of chip entanglement. Being double‑sided makes it economical in use: once one edge is worn, the insert can be indexed to present a fresh cutting edge. The combination of the PVD coating and the chosen substrate minimises unplanned tool changes and supports higher machining uptime, contributing to a more efficient production flow in serial turning operations.

Practical guidance for selection and use

With a corner radius of 1.2 mm, this insert suits medium‑finishing passes where a balance between strength and surface quality is required; larger radii favour strength, smaller radii favour sharpness. Choose the chipbreaker and grade according to workpiece material and machine stability — AH8015 performs well on heat‑resistant alloys but can be used broadly across alloyed steels with adapted cutting data. If unsure whether the geometry or grade fits a specific job, Metav Werkzeuge provides specification support and can advise on compatible holders and clamping kits.

FAQ

Which materials is this insert suited for?
The CNMG120412 AH8015 insert is primarily designed for heat‑resistant alloys; the AH8015 PVD‑coated carbide also performs well in a broad range of alloyed steels when cutting data are adjusted.

How does the double‑sided chipbreaker affect productivity?
A double‑sided chipbreaker on this Tungaloy turning insert enables consistent chip control and provides two usable cutting edges per insert, reducing changeover frequency and improving overall machining uptime.

What does the 1.2 mm corner radius mean for surface finish?
A 1.2 mm corner radius balances edge strength and surface quality: it supports medium finishing passes and offers greater resistance to edge chipping compared with smaller radii.

How to confirm holder compatibility for CNMG120412 inserts?
Compatibility depends on the insert form, relief angle, tolerance class, fastening method, size and thickness; check the holder's specification to match the ISO CNMG120412 geometry and the 4.76 mm plate thickness.

Is the insert reversible and how many edges are available?
The CNMG120412 AH8015 is double‑sided and indexable, providing multiple cutting edges; edges can be indexed according to wear pattern and machining requirements.
