CNMG 120408 AH8015 indexable turning insert by Tungaloy — PVD‑coated carbide, rhombic 80°

CNMG 120408 AH8015 is an ISO‑standard indexable turning insert for external and internal turning, optimised for heat‑resistant alloys.

• ISO‑standard CNMG120408 geometry
• PVD‑coated carbide AH8015 for heat‑resistant alloys
• Rhombic 80° form with 0.8 mm corner radius
• Double‑sided chipbreaker, cylindrical through‑hole

High‑productivity machining of heat‑resistant alloys

The PVD‑coated AH8015 grade provides a balanced combination of wear resistance and cutting‑edge stability, making it a first choice for machining temperature‑resistant alloys. In practice this means longer effective tool life under higher cutting temperatures and fewer unscheduled insert changes, which supports steady production rates and reduced tooling costs. The PVD coating helps resist abrasive conditions and contributes to consistent surface quality during extended runs.

Geometry designed for repeatable, accurate results

The rhombic insert shape with an 80° approach angle and a 0.8 mm corner radius delivers a dependable compromise between strength and finish. The 80° geometry gives good support to the cutting edge for robust cuts, while the modest corner radius helps maintain surface integrity without excessive cutting forces. With an insert thickness of 4.76 mm and size 12 mm, the component suits a wide range of ISO holders and set‑ups where stability and repeatability are required.

Controlled chips and fewer process interruptions

A double‑sided chipbreaker and the insert’s optimised land geometry promote predictable chip formation when turning difficult alloys. Predictable chips reduce the risk of re‑work and tool interference, enabling more reliable cycle times. The cylindrical through‑hole ensures secure clamping and simple indexing, allowing both faces of the insert to be used and thus lowering per‑cutting‑edge cost.

System compatibility and handling advantages

Compatibility with the clamping system is governed by form, free angle, tolerance class, fastening method, size and thickness; this ISO‑classified insert integrates into standard toolholder systems when specifications match. The insert is supplied as an ISO‑standard component and can be used with the appropriate insert seat, clamp and screw. For workshops prioritising fast tool changes and consistent results, the combination of ISO conformity, PVD‑coated carbide and practical geometry offers clear process advantages.
