CPMT 09T304 NS9530 Tungaloy – Indexable turning insert (rhombic 09, 80°)

The CPMT09T304 NS9530 Tungaloy is an ISO-standard indexable insert designed for fine finishing of steel components in turning applications.

• Fine finishing for steel with sharp cutting edge
• Uncoated cermet grade NS9530 for superior surface
• Rhombic 09 geometry with 80° cutting angle
• Cylindrical hole with single-sided countersink

High-quality finishing with reduced cutting forces

The insert is produced as a finishing grade and uses the NS9530 composition, an uncoated cermet developed for low cutting forces and a high surface finish on steel. This composition creates a naturally sharp cutting edge that excels in continuous feeds and small depths of cut, reducing the need for secondary finishing. The result is consistent part quality with fewer rejects and less rework, which supports stable throughput in mixed production runs while maintaining dimensional and surface tolerances.

Predictable mounting and dimensional stability for repeatable setups

Built to the ISO-standard CPMT09T304, the geometry and tolerancing simplify selection of a compatible holder: form, 11° clearance angle, tolerance class, fastening method, size and 3.97 mm thickness are decisive factors. The insert features a 0.4 mm radius, rhombic 09 shape and an 80° included angle, with a cylindrical hole and a single-sided countersink (40°–60°) to ensure secure clamping. These attributes support repeatable tool indexing and predictable tool life under comparable cutting conditions.

Application focus: efficient turning and controlled chip formation

Intended for turning, the insert is particularly suitable for external and internal finishing cuts where surface integrity matters. The single-sided chipbreaker concept helps maintain consistent chip control when matched to the workpiece material and machining stability. Selecting this finishing insert enables shorter cycle times for final passes and supports efficient production of turned components with a premium surface appearance and dimensional fidelity.

FAQ

What materials is this insert intended for?
The CPMT09T304 NS9530 Tungaloy insert is specified as a finishing grade for steel and is optimised to give a high-quality surface finish on continuous cuts.

Is the insert compatible with standard ISO holders?
Yes, the insert follows the ISO designation CPMT09T304; compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness.

What makes NS9530 different from coated grades?
NS9530 is an uncoated cermet designed to provide a naturally sharp edge and low cutting forces, prioritising surface quality for finishing over the wear resistance provided by coated grades.

Can this insert be used for both external and internal turning?
The insert is suitable for both external and internal turning operations when the holder and setup match the insert geometry and clamping requirements.

How does the chipbreaker design affect performance?
The one-sided chipbreaker supports reliable chip control during finishing passes when matched to material, feed and stability, helping maintain surface quality and process consistency.
