CNMG 120402 AH8015 Tungaloy — ISO turning insert for general turning applications

CNMG 120402 AH8015 Tungaloy is an ISO‑normed indexable insert designed for turning, especially suited to heat‑resistant alloys and general-purpose turning operations

• ISO‑normed 80° rhombic geometry
• PVD‑coated carbide AH8015 grade
• Double‑sided with cylindrical hole
• 0.2 mm corner radius for precision
• 4.76 mm thickness for stable clamping

Reliable performance for heat‑resistant alloys

The combination of a PVD‑coated carbide substrate and the AH8015 grade provides a balanced mix of wear resistance and cutting edge stability, making the insert a dependable choice when machining heat‑resistant alloys. The coating reduces adhesive wear and improves surface finish under elevated temperatures, while the substrate maintains flank and crater wear control. For production environments this means longer tool life and greater process consistency, which reduces downtime and the need for frequent insert changes.

Secure clamping and ISO compatibility minimise setup risk

Designed as an ISO‑normed insert, compatibility with matching holders depends on form, relief angle, tolerance class, clamping method, size and thickness. The 80° rhombic geometry combined with a cylindrical hole and double‑sided design ensures a secure seat in the pocket and straightforward indexing. The standard format simplifies tool inventory and reduces set‑up errors, delivering stable cutting conditions that help maintain part tolerances and surface quality across shifts.

Precision features that improve part quality

A 0.2 mm corner radius provides a controlled transitional edge that helps achieve consistent surface finish without sacrificing dimensional control. The rake angle of 0° supports robust cutting for a range of feed and depth settings, while the 4.76 mm thickness contributes to resistance against vibration and edge chipping in heavier cuts. These characteristics translate into measurable benefits: fewer rejects, predictable tool change intervals and improved throughput in mixed‑material production.

Application guidance and practical advantages

The insert is recommended for external and internal turning operations where a general-purpose grade for difficult, heat‑resistant materials is required. The double‑sided chipbreaker design extends usable life per index and keeps stock of spares to a minimum. When selecting a holder, match form, clearance and tolerance class to secure the best performance; following these steps ensures the insert achieves its expected durability and accuracy in daily use. The product is identified as CNMG120402 within Tungaloy’s AH8015 offering and suits workshops seeking a balance of economy and stable chip formation.

FAQ

What materials is this insert suitable for?
The CNMG120402 AH8015 insert is optimised for machining heat‑resistant alloys; the AH8015 grade provides balanced wear resistance and edge stability for such materials.

How is the insert mounted in a holder?
Mounting requires a matching ISO‑style holder that fits the 80° rhombic form, thickness and the cylindrical hole; secure clamping ensures correct seating and repeatable performance.

Can the insert be indexed to use both sides?
Yes, the insert is double‑sided, allowing indexing to the unused edge to extend usable life and reduce tooling costs.

What does the 0.2 mm corner radius mean for surface finish?
A 0.2 mm corner radius gives a controlled edge transition that improves surface finish while maintaining dimensional accuracy in turning operations.

Is the AH8015 coating suitable for high‑temperature cutting?
The PVD‑coated AH8015 grade is specifically selected for elevated temperature resistance and stable wear behaviour during cutting of heat‑resistant alloys.
