SNMG120408 AH8015 Tungaloy insert — ISO SNMG square turning insert, 90° geometry, 0.8 mm radius

The SNMG120408 AH8015 is an ISO‑standard square turning insert designed for external and internal turning applications on heat‑resistant alloys and similar materials.

• ISO‑standard SNMG geometry
• PVD‑coated carbide AH8015 grade
• 0.8 mm nose radius for stable cutting
• Double‑sided with cylindrical hole

High‑performance grade for heat‑resistant alloys

The combination of a PVD‑coated surface and the AH8015 carbide formulation gives a measured balance between wear resistance and edge stability, making the insert suited to continuous and interrupted turning of heat‑resistant alloys. The coating improves resistance to abrasive and adhesive wear at elevated temperatures, which translates into longer productive cutting lengths and more predictable tool life. This performance advantage supports higher metal removal rates without compromising component surface quality.

ISO compatibility and geometry for straightforward integration

The SNMG form is an established, ISO‑standard geometry that fits a broad range of external holders and boring bars when matching shape, relief, tolerance class, fastening, size and thickness. The SNMG120408 designation denotes the square outline with a 12 mm nominal size and a plate thickness of 4.76 mm, while the insert features a cylindrical hole and a 0° relief angle, enabling secure clamping and consistent seating. When selecting a holder, confirm these parameters to ensure repeatable clamping and optimal cutting geometry.

Productivity gains through stable chip control and indexing

A double‑sided insert reduces tooling cost per cutting edge and supports quick indexing to present a fresh edge. The integrated chipbreaker should be matched to workpiece material and cutting conditions; the correct chipformer reduces cutting forces, improves chip evacuation and enhances the resulting surface finish. The balanced character of this grade helps deliver consistent machining results, increased productivity and less frequent tool changes in medium‑to‑heavy turning operations.

Practical system considerations and handling

This insert forms part of a complete turning system comprising the ISO‑standard insert, a suitable external holder or boring bar, a shim/clamping set and replacement screws. The 0.8 mm radius produces a robust cutting edge suited to general turning tasks where edge strength and finish are both priorities. For best results, select the appropriate chipbreaker and match the AH8015 grade to the workpiece alloy and operational stability; the combination ensures reliable performance in both continuous and interrupted cuts.

FAQ

What materials is this insert suitable for?
The SNMG120408 AH8015 insert is optimised for heat‑resistant alloys and similar materials; the AH8015 grade balances wear resistance and edge robustness for reliable turning results.

Is the insert indexable and economical to use?
Yes — the insert is double‑sided, allowing rotation to fresh cutting edges and reducing tooling cost per effective edge.

What is the nose radius and how does it affect machining?
The nose radius is 0.8 mm, offering a strong edge that improves tool life and supports a good balance between surface finish and edge stability.

Which holders are compatible with this SNMG insert?
Compatibility is determined by matching the insert form, relief angle, tolerance class, fastening, size and thickness; ISO‑standard SNMG holders designed for the listed dimensions will accept this insert.

How does the AH8015 grade perform compared with other grades?
AH8015 is a PVD‑coated carbide grade intended as a first choice for general machining of heat‑resistant alloys, providing an even compromise between wear resistance and cutting‑edge stability.
