SNMG120408 AH8015 Tungaloy turning insert — PVD‑coated carbide, 90° square

A SNMG120408 AH8015 indexable turning insert engineered for external and internal turning operations, compatible with ISO‑standard holders and intended for heat‑resistant alloys.

• ISO SNMG shape for standard holders
• PVD‑coated carbide grade AH8015
• Double‑sided with cylindrical hole
• 0.8 mm corner radius, 90° included angle

Consistent edge life for heat‑resistant alloys

The SNMG120408 insert combines a PVD‑coated carbide substrate with the AH8015 grade to balance wear resistance and edge stability in the machining of heat‑resistant alloys. The coating and substrate chemistry reduce flank wear at elevated temperatures and permit sustained cutting speeds, which leads to longer tool life and fewer indexings. Where surface finish and repeatability matter, the insert’s geometry and stable cutting edge support consistent dimensional results and predictable tool change intervals.

Designed for straightforward holder compatibility and clamping

Compatibility with the chosen holder depends on the insert’s form, clearance angle, tolerance class, fastening, size and thickness; the SNMG120408 follows ISO provisions to ensure interchangeability with common external holders and boring bars. The square plate and cylindrical hole enable secure clamping with standard screws and underlays; the 4.76 mm thickness and 12 mm plate size give the rigidity needed for stable turning. This pragmatic design reduces set‑up time and minimises vibration, improving process stability and the quality of the finished component.

Practical chip control and economical use

The double‑sided chipbreaker layout and reversible configuration make the insert cost‑effective in high‑volume production: two usable cutting edges per side increase the number of indexings before replacement. For general turning, the balanced geometry of the chipformer supports controlled chip flow and reduces the risk of built‑up edge when machining difficult alloys. Selecting AH8015 allows a broad coverage of materials while keeping tool inventory simple — a pragmatic choice for job shops and production lines seeking predictable performance.

FAQ

What materials is this insert suitable for?
The SNMG120408 AH8015 insert is optimised for heat‑resistant alloys; the AH8015 PVD coating gives a balance of wear resistance and edge stability for a wide material range.

Is the insert reversible and how many cutting edges are available?
The SNMG120408 is double‑sided and reversible, providing multiple usable cutting edges per insert to improve economy in production.

Which holders are compatible with this ISO insert?
ISO‑standard holders that match the SNMG form, size (12 mm), thickness (4.76 mm), hole style (cylindrical) and fastening type are compatible; ensure matching tolerance class and relief angle.

What is the purpose of the 0.8 mm corner radius?
A 0.8 mm corner radius offers a compromise between edge strength and fine profile control, improving resistance to chipping while maintaining acceptable surface finish in turning.

Can the SNMG120408 be used for internal turning?
Yes, the geometry and hole style support use in suitable boring bars for internal turning as long as the holder and setup provide adequate rigidity.
