CNMG120408 AT9530 — ISO indexable turning insert, coated cermet, 80° by Tungaloy

The CNMG120408 AT9530 is an ISO‑standard rhombic indexable insert for turning, optimised for finishing and light machining of steel where surface quality and predictable wear are required

• Rhombic CNMG geometry, 80° cutting angle
• Coated cermet grade AT9530 for fine finishing
• 0.8 mm corner radius for consistent edge strength
• Cylindrical hole for secure clamping

Higher-quality finishes with predictable wear

The combination of a coated cermet grade and the rhombic geometry enables stable cutting behaviour during finishing operations. The AT9530 composition is designed for low and uniform wear, which translates into longer intervals between indexing and a consistently improved surface finish. Where tight tolerances and repeatable quality are needed, this insert provides a measurable increase in process reliability without complex parameter changes.

Easy integration into ISO tooling systems

Designed to conform to ISO dimensions, the insert integrates with standard external holders and boring bars; compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness. The cylindrical hole and standard shank geometry simplify clamping, while the 0° relief specification is suitable for many finishing set-ups. This reduces machine downtime for changeovers and supports efficient workshop logistics.

Better chip control and application versatility

A double-sided chipbreaker and the insert’s geometry promote orderly chip formation during light cutting, helping to avoid rework and tool-related stoppages. The grade is aimed at finishing and light machining of steel, favouring applications that prioritise surface integrity over heavy metal removal. Selecting the appropriate chipbreaker and cutting parameters will enable both improved throughput and consistent part quality.

FAQ

What materials is this insert suitable for?
The CNMG120408 AT9530 Tungaloy insert is intended primarily for finishing and light machining of steel; the AT9530 grade offers uniform wear for improved surface integrity.

Is the insert reversible or indexable?
Yes, the insert is double‑sided and indexable, providing multiple usable cutting edges before replacement or regrinding is necessary.

Which holder types are compatible with this geometry?
Compatibility requires a holder that accepts ISO CNMG plates and matches the form, clamping method, thickness (4.76 mm) and tolerance class of the CNMG120408 insert.

How does the chipbreaker affect performance?
The double‑sided chipbreaker promotes controlled chip formation in finishing operations, aiding surface quality and reducing the likelihood of chip-related interruptions when using the CNMG120408 AT9530.

Are there recommended cutting data for finishing steel?
Cutting data depend on machine rigidity and workpiece setup; the CNMG120408 AT9530 performs best at moderate feeds and speeds typical for finishing cuts—select parameters to favour surface finish over material removal.
