SNMG 120404 AH8015 Wendeplatten - Tungaloy

The PVD‑coated AH8015 cemented carbide insert pairs wear resistance with cutting‑edge stability and a 0.4 mm corner radius for steady surface finish and extended tool life; order via Metav Werkzeuge or contact our consultants for holder compatibility.

SNMG 120404 AH8015 – ISO turning insert, PVD‑coated carbide (Tungaloy)

SNMG120404 AH8015 is an ISO‑normed square indexable turning insert designed for external and internal turning, optimised for the general machining of heat‑resistant alloys.

• PVD-coated cemented carbide grade AH8015
• 0.4 mm corner radius for consistent surface finish
• Suitable for heat‑resistant alloys and general turning
• Double-sided chipbreaker with cylindrical hole

High‑temperature performance with balanced wear and edge stability

The SNMG120404 AH8015 insert uses a PVD coating paired with cemented carbide to achieve a balance between wear resistance and cutting‑edge stability. This composition makes the insert particularly suitable for machining heat‑resistant alloys, where temperature resistance and predictable flank wear are decisive for process security. In practice, the coated grade sustains cutting forces longer and reduces the frequency of insert changes, supporting a smoother production flow and more consistent part quality.

Geometry that secures finish and clamping reliability

The square form with a 0.4 mm corner radius and a nominal 90° principal cutting angle delivers a controlled cutting edge for repeatable surface quality. The double‑sided chipbreaker contributes to stable chip formation and allows economical use of the insert by providing usable faces on both sides. A cylindrical hole and standardised geometry ensure secure clamping in ISO‑compatible holders; the zero‑degree relief angle promotes full‑face engagement where required. For less experienced users, a larger corner radius generally improves finish at higher feeds, while a smaller radius favours sharper detail and lighter cutting forces.

Productivity and economy through reduced downtime

With its balanced grade and robust coating, this insert aims to lengthen service intervals and reduce scrap caused by unpredictable wear. The AH8015 chemistry and PVD surface treatment combine to lower adhesive and abrasive wear mechanisms when machining demanding materials, which in turn reduces machine idle time and tooling costs per part. Selecting the correct chipbreaker and matching holder geometry maximises productivity gains; the standardised ISO form simplifies stock management and replacement, delivering measurable cost‑benefit in continuous production environments.

ISO compatibility and practical integration into existing toolsets

As an ISO‑normed indexable plate, the insert is compatible with holders that match the ISO 120404 geometry by form, free clearance, tolerance class, fastening method, size and thickness. The system comprises the ISO plate, a suitable external holder or boring bar, and the necessary backing and clamping sets. If holder matching or process parameters require clarification, Metav Werkzeuge provides technical consultation and can advise on optimal holder selection, clamping sets and cutting data to suit the specific material and machining strategy.

FAQ

What materials is this insert suited for?
The SNMG120404 AH8015 insert is designed as a first choice for the general machining of heat‑resistant alloys and covers a broad range of steels and alloyed materials when the AH8015 grade is appropriately matched to the workpiece.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius offers a compromise between surface finish and edge strength; it reduces the risk of edge chipping compared with finer radii while preserving good surface integrity at typical turning feeds.

Is the insert compatible with standard ISO holders?
Yes; the plate follows ISO geometry and is compatible with holders that match ISO 120404 by form, free clearance, tolerance class, fastening and thickness — verify holder dimensions before assembly.

What advantages does the PVD coating provide?
The PVD coating on the cemented carbide substrate enhances wear resistance and heat resistance, improving tool life and process stability during higher temperature cutting operations.

Does the cylindrical hole affect clamping reliability?
The cylindrical hole facilitates secure clamping and consistent seating in compatible clamping sets, which supports repeatable positioning and reliable cutting performance.
