CNGG120408 NS9530 Tungaloy ISO indexable turning insert, rhombic, 80° for turning

The CNGG120408 NS9530 is an ISO indexable turning insert designed for finishing operations on steel, offering a sharp cutting edge and a geometry optimised for continuous cuts

• ISO indexable turning insert, 80° geometry
• Uncoated cermet grade NS9530
• 0.8 mm corner radius for high surface finish
• Cylindrical hole, double-sided chipbreakers

Consistent finishing and reduced cutting forces

The NS9530 grade is an uncoated cermet engineered for fine finishing on steel, delivering a sharp cutting edge that reduces ploughing and results in low cutting forces. This behaviour leads directly to improved surface quality and repeatable cylindricity when performing light, continuous cuts. For users unfamiliar with cermet, it is a ceramic–metal composite that prioritises edge sharpness and wear resistance at finishing speeds; this means better part appearance and less need for secondary polishing when compared with coarser grades.

Reliable fit and stable mounting for predictable machining

Manufactured to ISO dimensions, the insert matches standard holders when form, relief angle, tolerance class, fastening method, size and thickness align. The combination of 80° geometry and a 0° relief angle gives robustness in radial engagement while the cylindrical hole and secure fastening reduce micro-movement during cuts. The double-sided design with double-sided chipbreakers allows indexable use on both faces, extending tool life per cutting edge and simplifying inventory management for production environments.

Practical guidance for application and process optimisation

Designed primarily for external and internal turning, the indexable plate excels with small depths of cut and continuous feed conditions. Select the appropriate chipbreaker and the NS9530 grade when the priority is surface finish rather than heavy interrupted cuts. For process planners, the benefits are straightforward: consistent chip formation, lower rework rates and predictable tool-change intervals. If finishing stainless or other alloys, verify feed and speed windows for cermet grades to maintain edge life and avoid thermal shock.
