CNMG090408 GT9530 Tungaloy indexable insert — ISO turning insert for turning

A CNMG090408 GT9530 indexable insert engineered for finishing to light universal turning of steel, delivering improved surface finish and reliable wear resistance in stable machining conditions

• Coated cermet GT9530 for extended tool life
• ISO CNMG 09, rhombic 80° geometry
• Double-sided insert with cylindrical hole
• 0° relief angle and 0.8 mm corner radius

Enhanced finish and predictable tool life

The coated cermet GT9530 grade is formulated for finishing and light universal turning, combining a wear-resistant cermet substrate with a tailored coating to reduce abrasive wear and maintain edge integrity. In practice this translates into a more consistent surface finish and longer intervals between indexings when machining steel under stable conditions. Cermet inserts excel where fine surface quality matters: the hardened surface of the cermet matrix resists adhesion and maintains a keen cutting edge, while the coating further postpones flank wear. Compatibility with ISO holders is ensured by the standard CNMG geometry and specified thickness.

Stable geometry for versatile turning operations

The rhombic 80° geometry and the standard CNMG form permit both external and internal turning with effective access to shoulders and contours. The 0° relief angle suits rigid set-ups where minimal tool overhang and high stability are priorities, enabling repeatable dimensional tolerance and surface control. The double-sided design provides two cutting edges per indexed side, while the cylindrical central hole ensures secure clamping and consistent seat location. For optimum results, select the chipbreaker and grade variant that align with workpiece stability and the intended cut depth.

Practical handling that reduces downtime

A thickness of 4.76 mm and a 0.8 mm corner radius provide a good balance between edge strength and the ability to produce fine finishes; the corner radius stabilises the cut and helps avoid chatter in steady conditions. The CNMG format, combined with double-sided use, reduces tooling costs by increasing edge economy and simplifying spare-part management. Replacement is straightforward: the insert, holder, clamp and screws form the system and can be serviced without complex adjustments, which lowers machine downtime and contributes to predictable production cycles.

Brand performance and process reliability

Made by Tungaloy, the insert benefits from a manufacturing approach that emphasises consistent cutting-edge quality and modern grade development. The combination of a cermet substrate and applied coating supports reliable wear behaviour and repeatable machining performance across production runs. For operations prioritising surface quality and extended edge life in turning steel, this insert presents a processing-stable solution that complements productivity goals while maintaining cost-efficiency.

FAQ

What workpiece materials is this insert designed for? This insert is intended primarily for machining steel in finishing to light universal turning applications, utilising the GT9530 coated cermet grade for improved surface finish and wear resistance.

How many usable cutting edges does the insert provide? The double-sided construction gives multiple usable edges; each side can be indexed to provide additional cutting edges before replacement is required.

Which geometry and holder features are required for compatibility? Compatibility depends on matching the CNMG shape, 80° geometry, plate thickness, relief angle and clamping style; use a holder designed for CNMG inserts with a cylindrical-clamping arrangement.

What finish can be expected with a 0.8 mm corner radius? A 0.8 mm corner radius offers a compromise between edge strength and surface quality, delivering consistent finishes while reducing the risk of edge chipping in stable set-ups.

How is the insert secured in the toolholder? The insert uses a central cylindrical hole and standard clamp/screw fixation; proper torque and a matching clamping seat ensure repeatable location and secure fixation
