SNMG 120408 AH8015 turning insert — PVD-coated cemented carbide — Tungaloy

SNMG120408 AH8015 is an ISO-format, square indexable insert for general turning applications, optimised for heat‑resistant alloys and stable, repeatable machining.

• SNMG120408 format, 90° square insert
• PVD-coated carbide grade AH8015 for alloys
• 0.8 mm corner radius, 0° clearance angle
• Double-sided with cylindrical hole for secure clamping

Reliable performance for challenging alloys

The PVD-coated AH8015 grade provides a balanced combination of wear resistance and edge stability, making it suited to the machining of heat‑resistant alloys where flank wear and thermal loads are critical. As a cemented carbide insert with a robust coating, it sustains cutting forces and thermal cycles better than uncoated grades, leading to longer effective tool life and more consistent component quality. The result is predictable cycle times and fewer unexpected tool changes, which supports higher productivity in production turning.

Economical clamping and rapid indexability

The square, double‑sided design with a cylindrical hole enables secure clamping in standard ISO toolholders and allows rotation to a fresh cutting edge without immediate replacement. The reversible geometry reduces tooling cost per cutting edge and simplifies inventory management. The insert’s compatibility with holders is determined by its form, free angle, tolerance class, fixation method, size and thickness, so selecting the correct clamp and setting prevents runout and ensures stable cutting conditions.

Clear specification for fast setup and safe results

Marked as ISO SNMG120408, the insert features a 0.8 mm corner radius and a thickness of 4.76 mm, with an effective inscribed circle size of 12 mm and a 90° cutting angle. The 0° clearance angle suits a range of external and internal turning tasks where rigid setups are available. These measurable parameters support straightforward programming and reproducible setups, helping to reduce setup time and ensure dimensional consistency across batches.

Practical benefits for daily workshop use

The combination of PVD coating and the AH8015 substrate gives a good compromise between toughness and hardness, suitable when both wear resistance and edge security are required. In practice this means fewer interrupted operations, improved surface finish stability and a lower overall cost per component when machining demanding materials. The standard ISO form also eases replacement and cross‑compatibility with existing holder systems, allowing integration into established production chains with minimal adjustment.
