SNMG120408 AH8015 ISO turning insert — PVD-coated carbide, 0.8 mm radius (Tungaloy)

SNMG120408 AH8015 is an ISO‑standard square indexable insert developed for external and internal turning of heat‑resistant alloys, offering a balance of wear resistance and edge stability.

• PVD-coated carbide grade AH8015
• 0.8 mm corner radius for robust cuts
• Square SNMG form with cylindrical hole
• Double-sided insert reduces inventory

Consistent cutting performance for heat‑resistant alloys

The SNMG120408 AH8015 insert combines a PVD-coated surface with a carbide substrate to deliver a well‑balanced performance between wear resistance and cutting edge stability. The AH8015 grade is tuned as a first choice for machining heat‑resistant and high‑temperature alloys, which means fewer unscheduled tool changes and more predictable cycle times. The PVD layer improves surface hardness and thermal resistance, so the cutting edge retains geometry longer under elevated temperatures, reducing rework and improving cost per part.

Easy integration with ISO tooling and secure clamping

Designed to the ISO SNMG120408 standard, the insert fits common external holders and boring bars where compatibility depends on shape, relief angle, tolerance class, fastening, size and thickness. The cylindrical hole and square form enable reliable clamping and straightforward indexation. With a plate thickness of 4.76 mm and a compact 12 mm form size, the insert supports quick changeovers and simple stocking strategies, helping to maintain machine uptime and streamline toolroom logistics.

Predictable chip control and improved surface finish

The insert is double-sided, providing two usable cutting edges per side and lowering tooling costs per edge. The matched chipbreaker geometry allows controlled chip formation; selecting the correct breaker for the material and operation ensures stable cutting and consistent surface quality. The 0.8 mm corner radius is a compromise between edge robustness and finish: it absorbs light interruptions and vibration while still enabling fine surface results in both external and internal turning.

Operational efficiency and reliable process security

Using a standardised insert grade and form reduces variability across production runs. The combination of a stable substrate and PVD-coated surface lowers tooling expenditure through extended life and reduced change frequency, contributing to predictable machining costs. Backed by Tungaloy’s engineering focus on practical, repeatable cutting performance, the insert supports an efficient workflow and dependable component quality in batch or continuous production.
