CNGG 090308 NS9530 indexable turning insert by Tungaloy — rhombic ISO finishing grade

A CNGG090308 NS9530 indexable insert engineered for external and internal turning, offering a sharp cermet grade for fine finishing and continuous cut conditions

• ISO rhombic insert CNGG 090308
• Uncoated cermet grade NS9530
• Sharp edge for superior surface finish
• Double-sided chipbreaker with central hole

High-precision finishing with a cermet edge

The uncoated cermet NS9530 is designed for low cutting forces and excellent surface quality when machining steel in finishing passes. Its finely honed cutting edge reduces built-up edge and promotes a stable cutting action during continuous cuts and small depths of cut. This results in consistent part finish and reduced need for secondary operations, making the insert particularly suitable for demanding finishing tasks where dimensional accuracy and surface integrity matter.

ISO compatibility simplifies tool selection and set-up

The insert follows ISO dimensions and a rhombic form that match standard external holders when the form, free clearance, tolerance class, mounting and size correspond. Because holders and clamping sets are selected according to these parameters, the standardisation shortens tool-change planning and ensures repeatable seating and orientation. Clear information on size 09, thickness and hole style allows quick cross-referencing with existing toolholders, reducing set-up time on the shop floor.

Robust edge stability and economical indexing

As an uncoated carbide/cermet finishing grade, this insert offers a stable edge for many finishing cycles while maintaining an attractive cost-to-life ratio. The double-sided chipbreaker extends available cutting edges per index and the central cylindrical hole enables secure, repeatable clamping. Together, these features reduce tool-change frequency and inventory complexity, supporting productive machining sequences and controlled operating costs.

Practical applications and machining guidance

Recommended for external and internal turning, the insert excels on continuous cut applications and small depth-of-cut finishing. Key geometry data support correct application: corner radius 0.8 mm, cutting angle 80°, clearance 0° and thickness 3.18 mm. These parameters favour steady contact with the workpiece and a fine surface outcome; match the insert to a suitable finishing holder and select cutting parameters that emphasise stability and low feed to exploit the grade’s strength.

FAQ

Is this insert suitable for finishing steel?
Yes. The CNGG090308 NS9530 Tungaloy insert is a finishing-grade cermet developed for steel, providing a sharp cutting edge and low cutting forces for high-quality surfaces.

Can the insert be used for internal turning as well as external turning?
Yes. The geometry and double-sided indexing make the insert suitable for both external and internal turning applications when matched with an appropriate ISO-compatible holder.

How is the insert fixed to the toolholder?
The insert features a central cylindrical hole for screw mounting and is compatible with ISO-style clamping systems; the design supports secure, repeatable seating.

What advantages does the double-sided chipbreaker offer?
A double-sided chipbreaker provides two usable cutting edges per index and helps control chip formation during finishing cuts, extending effective edge life and reducing downtime.

Which geometry values are most relevant when choosing a holder?
Key values are the insert designation, size 09, thickness 3.18 mm, corner radius 0.8 mm, and 80° cutting angle; holders must match these dimensions and the tolerance class for correct fit.
