CNMG 120412 AH8015 — Turning insert (PVD‑coated carbide) by Tungaloy

CNMG 120412 AH8015 is an ISO‑series rhombic turning insert designed for general machining of heat‑resistant alloys and similar demanding materials

• ISO‑compliant rhombic insert for turning
• PVD‑coated carbide for wear resistance
• Double‑sided chipbreaker for reliable swarf control

High‑performance grade for demanding turning applications

The CNMG120412 AH8015 turning insert combines a PVD‑coated surface with a wear‑resistant carbide substrate to deliver a compromise between edge stability and long life when machining heat‑resistant alloys. The ISO‑compliant geometry ensures compatibility with standard external holders and boring bars; fit is determined by form, clearance, tolerance class, attachment method, size and thickness. The rhombic shape with an 80° approach provides robust support in interrupted cuts while the corner radius 1.2 mm promotes a consistent cutting edge for medium‑to‑heavy feeds.

Predictable chip control and secure clamping for productivity gains

Built with a double‑sided chipbreaker, the insert allows use on both cutting edges, effectively doubling usable life and lowering tooling cost per component. The central cylindrical hole and matched fastening method ensure secure clamping and repeatable seating in the pocket; this reduces tool chatter and improves surface finish. For those less familiar with chipbreakers: the feature shapes and divides swarf so it evacuates reliably, reducing recutting and extending insert life. These engineering choices support higher process stability and improved throughput on production turning operations.

Practical selection advice and application scope

This indexable insert is tailored for turning operations—external and internal—where heat‑resistant or high‑temperature alloys are encountered; the AH8015 grade is a first choice for such materials due to its balanced wear resistance and edge strength. Choose the chipbreaker style and grade to match the component material and machining stability: more rigid set‑ups can use larger corner radii for improved surface quality, while unstable conditions may benefit from smaller radii and lighter cuts. Technical advisers at Metav Werkzeuge can provide cut‑data recommendations and holder compatibility checks to integrate this insert into existing tool systems.

FAQ

What materials is this insert suitable for? The CNMG 120412 AH8015 insert is specified for the general machining of heat‑resistant alloys and similar materials; the AH8015 grade balances wear resistance and edge strength for these applications.

How does the PVD coating affect performance? A PVD‑coated carbide substrate increases resistance to adhesive and abrasive wear on the cutting edge, helping the CNMG 120412 AH8015 maintain cutting performance at elevated temperatures and prolonging tool life.

Can the insert be used on both sides? Yes, the double‑sided chipbreaker design permits indexing to use both cutting edges, effectively extending the number of productive positions per insert.

Which holders are compatible with this ISO insert? Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; use holders specified for CNMG120412 geometry or consult Metav Werkzeuge for a holder match.

What benefits does the 1.2 mm corner radius provide? A 1.2 mm corner radius improves edge strength and surface finish under medium to heavy feed conditions, offering a stable cutting edge for many production turning tasks.
