CPMT 09T304 NS9530 ISO rhombic turning insert for finishing – Tungaloy

A CPMT09T304 NS9530 insert designed for precision external and internal turning, optimised for finishing steel with continuous cuts and small depths of cut

• ISO rhombic insert for finishing
• Uncoated cermet NS9530 for steel
• 0.4 mm nose radius, 80° rhombic form
• Cylindrical hole with single countersink

Achieve consistent high-quality finishes with a finishing-grade cermet

The uncoated cermet NS9530 is formulated as a finish-grade cutting material, providing a very sharp cutting edge that reduces cutting forces and promotes stable chip flow during continuous cuts. This results in a high surface finish on steel components and lowers the tendency for built-up edge at small feeds and light depths of cut. For operations where steady surface quality is critical, the grade’s geometry and edge form support predictable outcomes and reduced rework rates.

Stable seating and repeatable clamping for reliable tool life

The rhombic 80° included angle, combined with a 0.4 mm nose radius and a 11° clearance angle, gives a balance between edge strength and fine-detail capability. The insert’s cylindrical hole with a single-sided countersink (40°–60°) ensures accurate seating and repeatable positioning in an ISO-compatible holder; this stability reduces vibration and optimises tool life. The single-sided chipbreaker is tuned for finishing conditions so that chip control is maintained without compromising the finished surface.

Straightforward integration into ISO turning systems

Being part of an ISO indexable insert series, compatibility with holders depends on the insert’s form, clearance angle, tolerance class, clamping method, size and thickness. Select a matching external holder or boring bar, and confirm the clamping set and screw sizes for secure assembly. The carbide substrate and cermet cutting material combination supports predictable tool behaviour in finishing cycles, allowing process engineers to plan feeds and speeds conservatively and then optimise for throughput while keeping surface quality consistent.

FAQ

Which materials is this insert intended for?
The NS9530 grade of the CPMT09T304 insert is a finish-grade uncoated cermet optimised for machining steel, particularly where low cutting forces and excellent surface finish are required.

How does the 0.4 mm nose radius affect surface quality?
A 0.4 mm nose radius on the CPMT09T304 provides a compromise between fine-detail forming and edge strength, improving surface finish while maintaining resistance to minor edge wear during finishing passes.

Can this insert be used for internal turning as well as external turning?
Yes; the insert’s rhombic 80° form and ISO compatibility make it suitable for both external and internal turning when paired with the appropriate holder and secure clamping arrangement.

What does the hole style mean for clamping reliability?
The cylindrical hole with a single-sided countersink (40°–60°) ensures accurate seating and repeatable positioning in ISO-standard clamping systems, enhancing stability and reducing vibration during finishing operations.

Is the insert coated?
No; the NS9530 cutting material is supplied as an uncoated cermet, chosen to provide a sharp edge and superior finish on steel in continuous cutting conditions.
