SNMG120408 AH8015 Tungaloy insert — ISO turning insert, PVD‑coated carbide, 90° square

A SNMG120408 AH8015 Tungaloy insert designed for external and internal turning where a balance of wear resistance and cutting edge stability is required

• ISO‑standard square insert, 90° geometry
• PVD‑coated carbide AH8015 grade
• 0.8 mm corner radius for robust edges
• Double‑sided chipbreaker with centred hole

Reliable cutting performance for heat‑resistant alloys

The SNMG120408 AH8015 insert is engineered as an ISO‑standard turning insert for consistent machining of heat‑resistant alloys. The PVD‑coating on the carbide substrate improves wear resistance while maintaining edge strength, which supports longer tool life under elevated temperatures. The square, 90° geometry enables stable cutting forces for both facing and longitudinal turning, and the 0.8 mm corner radius helps to distribute loads at the cutting edge, reducing incidence of premature chipping. For those new to indexable tooling, the PVD finish is a thin, hard layer applied by physical vapour deposition to increase surface hardness without compromising toughness.

Simple integration into ISO toolholder systems

Compatibility is ensured by ISO conformity: form, relief angle, tolerance class, fastening method, size and thickness determine fitment. The insert’s dimensions (12 mm size, 4.76 mm thickness) and centre hole with cylindrical style allow straightforward mounting in standard external holders or boring bars. The double‑sided chipbreaker provides two usable cutting edges per index, improving economy and reducing changeover frequency. In practice this means quicker re‑indexing and predictable set‑up times, which supports efficient machine timetable planning and reduces operator downtime.

Predictable edge life and process stability

Choosing the AH8015 grade delivers a compromise between wear resistance and edge stability, aimed at productive turning of tough alloys. The geometry and chip control features are tuned for stable chip formation under varied cutting conditions; this reduces vibration and improves surface finish in one operation. For production environments, this predictability translates to fewer interruptions, more consistent part tolerances and better first‑pass yield. Where higher thermal loads are expected, the PVD layer contributes to performance retention, making this insert a reliable option for mixed‑material batches.
