SNMG120412 AH8015 turning insert (ISO 120412) — Tungaloy, PVD-coated carbide, 90°

The SNMG120412 AH8015 is an ISO-form turning insert designed for general external and internal turning of heat-resistant alloys, offering balanced wear resistance and edge stability.

• ISO SNMG120412 format, square 90° insert
• PVD-coated AH8015 carbide grade
• Double-sided chipbreaker, cylindrical hole
• Compatible with standard ISO holders

Predictable geometry for repeatable turning results

The ISO square, 90° SNMG geometry ensures a defined cutting edge and predictable cutting direction, which simplifies tool selection for both external and internal turning. The standardised format supports repeatable clamping and offers a reliable seating interface in compatible holders, reducing setup variation and downtime. With a corner radius of 1.2 mm the insert delivers a compromise between edge strength and achievable surface finish, making it suitable for medium- to heavy-cut operations where consistent form and tolerance retention are priorities.

Durable PVD-coated carbide for heat-resistant alloys

The AH8015 grade is a PVD-coated carbide optimised for the general machining of heat-resistant alloys; the coating improves wear resistance while the substrate maintains edge stability under thermal and mechanical loads. This combination lowers flank wear rates and extends tool life compared with uncoated grades, which leads to fewer insert changes and more stable process windows. The result is a cost-effective solution for shops that prioritise uninterrupted production and constant part quality when working with demanding materials.

Practical system compatibility and handling advantages

Designed as part of an ISO insert system, the plate works with standard external holders or boring bars and requires the usual clamping sets and screws for mounting. The insert is double-sided with a cylindrical hole, enabling indexable use and efficient stock rotation; the plate thickness of 4.76 mm contributes to rigidity while the square form provides four indexable edges. These features reduce tooling inventory complexity and support fast changeovers, which is especially advantageous in batch production or mixed-operation environments where adaptability and predictable tool life improve overall workflow.
