SNMG120408 AT9530 – Tungaloy indexable insert for turning, coated cermet, 0.8 mm radius

A SNMG120408 AT9530 indexable insert designed for precision external and internal turning, optimised for finishing steel components.

• ISO SNMG form for wide holder compatibility
• Coated cermet AT9530 for superior surface finish
• 0.8 mm corner radius for fine surface quality
• Cylindrical hole, double-sided chipbreaker

Consistent surface quality for finishing operations

The insert’s AT9530 grade is a coated cermet formulated for finishing and light machining of steel, delivering uniform wear and excellent microfinish. The combination of substrate and coating promotes stable cutting-edge behaviour, which helps reduce rework and downstream polishing. By selecting a fine 0.8 mm radius, the geometry supports tighter corner rounding and improved part appearance without sacrificing edge stability. For shops aiming for repeatable surface results, this geometry and grade reduce the need for secondary operations and help maintain dimensional tolerances.

Flexible compatibility and straightforward mounting

As an ISO SNMG-format insert with a cylindrical hole, the geometry ensures compatibility with a wide range of external holders and boring bars when the form, relief angle and thickness match. The insert thickness of 4.76 mm and the square plate form require a holder that accepts SNMG plates and the specified tolerance class. Correct selection of the clamping set and replacement screws is essential for secure seating and repeatable cutting performance. If holder matching or tolerance checks are required, Metav Werkzeuge offers application advice to confirm the correct tool assembly.

Effective chip control and longer tool life

The double-sided chipbreaker integrated into the plate supports predictable chip formation during finishing cuts, aiding swarf evacuation and machine cleanliness. Combined with the cemented carbide substrate and coating, the insert balances wear resistance with edge sharpness for longer productive life in low-to-medium cutting conditions. These attributes contribute to fewer index changes per part batch and a smoother production flow, improving throughput without compromising surface integrity.

Application guidance and support for process reliability

This insert is intended primarily for turning applications where surface quality and even edge wear are priorities. Typical system setup includes an SNMG plate, a compatible external holder or boring bar, and the appropriate underlay/clamping kit. Because compatibility is determined by plate form, relief angle, tolerance class, fastening method, size and thickness, it is advisable to verify holder specifics before purchase. If additional technical data or application tests are required, Metav Werkzeuge can assist with cutting parameter recommendations and tool-life expectations; contact via info@metav-werkzeuge.com or call +49 2822 7131930.
