SNMG120404 AH8015 SNMG turning insert (Tungaloy) — PVD-coated carbide, 0.4 mm radius

The SNMG120404 AH8015 is an ISO-standard indexable turning insert designed for general-purpose external and internal turning of heat-resistant alloys.

• ISO-compliant indexable insert
• PVD-coated carbide grade AH8015
• 0.4 mm corner radius for precision
• Double-sided design with cylindrical hole

Consistent cutting performance for demanding alloys

The combination of a PVD-coated carbide substrate and the AH8015 grade delivers a balanced mix of wear resistance and edge stability, making this insert well suited for machining heat-resistant alloys. The coating reduces adhesive wear and thermal damage during high-temperature cuts, while the carbide core maintains form stability. As a result, the insert supports longer uninterrupted production runs and fewer insert changes, which contributes to higher productivity and lower downtime in batch and serial manufacturing.

Smooth integration into ISO tool systems

Designed to the ISO indexable insert dimensions, the insert ensures compatibility with standard square holders and boring bars when form, clearance angle and clamping specifications match. The indexable insert is supplied with a central cylindrical hole for secure fastening and its square shape provides four usable cutting edges when indexed. Clear specifications for thickness, size and tolerance assist in selecting the correct holder and clamping set, reducing setup time and helping to maintain repeatable machining accuracy across tool changes.

Practical benefits for process reliability and surface finish

A 0.4 mm corner radius provides a balance between strength and finish: it improves edge robustness during interrupted cuts while enabling good surface quality on general turning operations. The double-sided design doubles the number of edges available per insert, improving cost-efficiency per cutting edge. When combined with the appropriate chipbreaker option for the chosen material and cutting conditions, the insert helps to control chip formation, decrease rework and deliver consistent part quality in production environments.

FAQ

Which materials are best machined with this insert? The SNMG120404 AH8015 insert from Tungaloy is specified as a first choice for machining heat-resistant alloys, offering a balance of wear resistance and edge stability suitable for such materials.

Is this an indexable, reusable cutting edge? Yes, the SNMG120404 AH8015 is an indexable, double-sided insert; each side provides cutting edges that can be rotated or indexed to expose a fresh edge.

What does the 0.4 mm radius mean for finishing and strength? A 0.4 mm corner radius gives enhanced edge strength for interrupted cuts while maintaining the ability to achieve good surface finish in typical turning operations with the AH8015 grade.

How does holder compatibility work for this insert? Compatibility depends on the insert form, relief angle, tolerance class, clamping method, size and thickness; the ISO designation 120404 helps identify matching square holders and boring bars.

Can this insert be used for both external and internal turning? Yes, the insert is intended for both external and internal turning applications, provided the correct holder and chipbreaker combination is selected for the specific workpiece material and machining stability.
