CCMT09T308 NS9530 CCMT ISO Turning Insert for Finishing by Tungaloy

The CCMT09T308 NS9530 is an ISO rhombic turning insert designed for precision finishing of steel in continuous-turning operations, providing a sharp cutting edge and stable chip control.

• Finishing-grade uncoated cermet NS9530
• Sharp cutting edge for low cutting forces
• 0.8 mm nose radius for high surface finish
• ISO CCMT rhombic insert with 7° clearance

Consistent finishing performance for steel components

The uncoated cermet NS9530 grade is developed for finishing applications on steel, offering a notably sharp cutting edge and reduced cutting forces that translate into a better surface quality and lower power draw. Cermet combines ceramic hardness with metallic toughness; this means the cutting edge resists wear while delivering a fine surface without the need for aggressive feeds. For continuous cuts and small depths of cut the geometry supports stable engagement, reducing vibration and repeatable part-to-part results. The result is improved process stability and fewer rework cycles.

ISO compatibility and mounting considerations for reliable set-up

Being an ISO-designated CCMT rhombic insert, compatibility with the toolholder is governed by form, relief angle, tolerance class, fastening, size and thickness. The insert features a 0.8 mm nose radius and a 7° relief angle; matching these values with the holder and correct clamping components ensures correct seat and repeatable positioning. The plate thickness of 3.97 mm and the cylindrical hole with one-sided countersink (40°–60°) are intended for standard ISO clamping systems. Selecting the correct top clamp or screw set and verifying the holder’s tolerance will preserve insert life and prevent movement under load.

Process reliability and practical recommendations for greater productivity

For high-quality finishes and consistent chip control, pair the insert’s single-sided chipbreaker and NS9530 grade with modest feed rates and continuous cutting conditions. The rhombic CCMT geometry supports both external and internal turning when combined with the appropriate holder or boring bar, and the smooth edge of the cermet grade reduces built-up edge tendencies on steel. These characteristics favour long service intervals in finishing operations and contribute to predictable tool-life. For best results, adapt cutting parameters to machine rigidity and part clamping, and choose a chipbreaker suited to the workpiece and depth of cut.

FAQ

What steels is this grade intended for?
The CCMT09T308 NS9530 Tungaloy turning insert is a finishing-grade, uncoated cermet developed for steels and provides a sharp edge for low cutting forces and excellent surface finish.

Can this insert be used for both external and internal turning?
Yes, the rhombic CCMT geometry and the specified dimensions allow use in both external and internal turning when mounted in a compatible holder or boring bar.

How does the 0.8 mm nose radius affect surface quality?
A 0.8 mm nose radius on the insert supports improved surface finish while maintaining acceptable edge strength for finishing feeds and shallow depths of cut.

What clamping features are required for correct installation?
The insert has a cylindrical hole with a one-sided countersink (40°–60°) and a 3.97 mm thickness; a matching ISO CCMT clamp and appropriate screws or underlay are required for secure seating.

Is this insert suitable for interrupted cuts?
This grade is optimised for continuous cutting and small depths of cut; interrupted machining may reduce edge life and should be evaluated against specific application conditions.
