CNMG090412 AH8015 CNMG ISO turning insert for turning — PVD‑coated cemented carbide by Tungaloy

The CNMG090412 AH8015 is an ISO‑standard rhombic turning insert designed for general turning of heat‑resistant alloys, offering a balanced combination of wear resistance and edge stability.

• PVD-coated cemented carbide AH8015
• 80° rhombic insert, 1.2 mm corner radius
• Double-sided chipbreaker, indexable design
• Cylindrical centre hole, 4.76 mm plate thickness

Consistent performance for heat‑resistant alloys

The grade AH8015 is a PVD-coated cemented carbide developed as a first choice for the general machining of heat‑resistant alloys. Its balanced chemistry provides improved wear resistance while maintaining cutting edge stability, which translates into fewer insert changes and steadier component quality. For operations where thermal loads are moderate to high, this insert gives a consistent tool life and helps sustain cycle‑time predictability on both external and internal turning applications.

Stable chip control and predictable indexability

With a double-sided chipbreaker and an indexable two‑edge design, chip formation is controlled across a range of feeds and depths of cut. The cylindrical centre hole and the ISO‑conforming geometry ensure secure clamping in compatible holders, reducing the risk of vibration and displacement during cutting. The result is improved process security, reduced rework, and more predictable maintenance intervals for production lines that demand repeatable output.

Design dimensions that simplify tooling choices

The 80° included angle and 1.2 mm corner radius paired with a 4.76 mm plate thickness make this rhombic insert a versatile option for semi‑finishing and medium turning tasks. ISO compatibility means selection of a matching external holder or boring bar hinges on form, clearance angle, tolerance class, fastening and size — all standard factors when matching inserts to toolholders. Choosing the correct combination minimises set‑up time and helps achieve the desired surface finish with straightforward parameters.

Operational benefits and economical machining

This indexable insert supports efficient machining by balancing durability and edge life, which can lower overall tooling costs through reduced consumption. The combination of PVD coating, robust substrate and a well‑designed chipbreaker contributes to stable cutting conditions, better surface integrity and consistent dimensional accuracy. For workshops focused on productivity, the insert’s characteristics support higher uptime and dependable performance when working with challenging alloy families.
