CNMG 090408 NS9530 indexable insert for turning – Tungaloy, rhombic form, 0.8 mm nose radius

CNMG090408 NS9530 Tungaloy indexable insert for precision turning, designed as an ISO-standard rhombic insert for finishing steel components with continuous cuts and fine surface requirements

• Uncoated cermet NS9530 for finishing
• Sharp cutting edge and low cutting forces
• Double-sided chipbreaker for stable machining
• Rhombic CNMG form with cylindrical hole

Consistent finishing performance for steel turning

The uncoated cermet grade NS9530 is optimised for finishing operations on steel, delivering a sharp cutting edge and low cutting forces that together reduce vibration and improve surface quality. As a finishing grade, the material composition promotes a fine, consistent microfinish under continuous cutting conditions and small depths of cut. The combination of the grade and the insert geometry reduces the likelihood of built-up edge and supports longer intervals between tool changes, which improves process stability on medium- and high-speed lathes.

Geometry and chip control that support productivity

The insert’s rhombic CNMG outline and double-sided chipbreaker provide reliable chip control and allow economical indexable use. The 0.8 mm nose radius balances edge strength with the ability to achieve tight surface tolerances, while the cylindrical hole simplifies accurate clamping in compatible holders. Compatibility with a holder depends on form, clearance angle, tolerance class, fastening method, size and plate thickness; correct matching ensures the insert sits precisely and transmits cutting forces efficiently, thereby reducing chatter and wear.

Application guidance and process advantages

Designed for external and internal turning, this grade is particularly suitable for continuous cuts and small feed rates where surface finish is critical. The NS9530 composition and sharp edge reduce required cutting forces, which benefits thin-walled parts and delicate components by lowering distortion risk. Where a fine surface is the priority, select this finishing insert and adjust cutting parameters to moderate speeds and reduced feed to exploit the grade’s strengths while maintaining tool life.

System integration and operational considerations

The insert is part of an ISO insert system that comprises the indexable plate, a matching external holder or boring bar, and a clamping/shim set with replacement screws. When planning tool setups, ensure the holder accommodates the CNMG form and plate thickness (4.76 mm) and that the fastening method matches the insert’s hole style to maintain repeatable seating. Regular inspection of the clamping torque and replacement screws preserves positional accuracy; maintaining correct assembly supports consistent part quality and predictable tool change intervals.

FAQ

What materials is this insert suited for?
The CNMG090408 NS9530 Tungaloy insert is specified as a finishing grade for steel, delivering low cutting forces and excellent surface finish for continuous turning operations.

How does the 0.8 mm nose radius affect results?
A 0.8 mm nose radius on the CNMG090408 provides a compromise between edge strength and surface finish, enabling tighter tolerances while maintaining sufficient robustness for finishing applications.

Is the insert compatible with my holder?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; Metav Werkzeuge can assist in confirming whether a specific holder matches the CNMG090408 dimensions and the cylindrical hole clamping.

What advantages does the uncoated cermet NS9530 offer?
The uncoated cermet NS9530 offers a sharp cutting edge and low cutting forces, which improve surface quality and reduce the tendency for built-up edge in finishing steel workpieces.

Can the insert be rotated or indexed to use the opposite edge?
The double-sided chipbreaker and CNMG geometry permit indexing to the opposing cutting edge, enabling economical use of both sides for consistent finishing performance.
