SNMG120404 AH8015 Tungaloy indexable turning insert — ISO standard, PVD‑coated

The SNMG120404 AH8015 is an ISO‑standard indexable turning insert designed for external and internal turning, offering a balanced combination of wear resistance and cutting‑edge stability for demanding alloys.

• ISO SNMG120404 standard insert
• PVD‑coated carbide AH8015
• Double‑sided chipbreaker design
• Cylindrical hole with secure seating

Reliable cutting performance for heat‑resistant alloys

The AH8015 grade is a PVD‑coated carbide developed as a first choice for general machining of heat‑resistant alloys, delivering a compromise between wear resistance and edge stability. In continuous turning operations this translates into steadier cutting forces and more predictable tool life, which reduces unplanned tool changes and improves throughput. The insert’s double‑sided chipbreaker supports controlled chip formation, lowering the risk of chip entanglement and contributing to consistent surface finish on workpieces.

Predictable compatibility and secure clamping for efficient setup

The ISO designation SNMG120404 guarantees dimensional compatibility with ISO holders when matching form, tolerance class, fastening and thickness. The insert is supplied in a square 12 mm size with a thickness of 4.76 mm, a corner radius of 0.4 mm and a 0° clearance angle; the cylindrical hole ensures reliable seating and repeatable location in the pocket. Together these attributes shorten set‑up time, maintain axial and radial position under load and simplify regrind or replacement procedures, supporting higher machine uptime and repeatable part quality.

Optimise process stability and tool life with a system approach

Made from carbide and finished with a PVD layer, this insert is intended for productive turning in systems that include a matching holder, underlay and clamping set. Selecting the correct chipbreaker and grade for the workpiece material helps to reduce cutting temperatures and wear, while the robust cutting edge promotes stable cutting at higher feed rates. For medium‑ to long‑run production, the combination of coating, geometry and secure fastening supports cost‑effective operation through fewer interventions and consistent dimensional results.

FAQ

What materials is this insert best suited for?
The SNMG120404 AH8015 insert is optimised for heat‑resistant alloys; the AH8015 grade balances wear resistance and edge stability for typical high‑temperature materials.

Can the insert be used for both external and internal turning?
Yes, the ISO‑format indexable insert is designed for both external and internal turning applications when mounted in a compatible holder.

How does the double‑sided chipbreaker improve machining?
The double‑sided chipbreaker on the SNMG120404 promotes consistent chip control, reducing the risk of chip entanglement and improving surface finish stability.

What dimensions are important when checking holder compatibility?
Key dimensions are the ISO designation, size (12 mm), thickness (4.76 mm), corner radius (0.4 mm) and the presence of the cylindrical hole for correct seating.

Is the AH8015 coating suitable for interrupted cuts?
The PVD‑coated AH8015 grade offers a good balance of toughness and wear resistance; it can be applied for interrupted cuts depending on workpiece material and cutting parameters.
