SCMT120408 NS9530 Tungaloy indexable milling insert — cermet finishing grade for milling

SCMT120408 NS9530 Tungaloy-Wendeplatte is a square indexable insert for milling, optimised for finishing steel with a sharp cutting edge and low cutting forces.

• Precise cermet finishing grade NS9530
• Sharp cutting edge for fine surfaces
• Single-sided chipbreaker for continuous cuts
• Compatible with Tungaloy milling systems

Exceptional finishing quality with cermet NS9530

The uncoated cermet NS9530 is developed as a finishing grade for steel, combining a very sharp cutting edge with reliable wear resistance. This composition reduces built-up edge and lowers cutting forces, which helps to achieve a high surface quality on machined faces and shoulders. For operations with small depth of cut and continuous cutting, the grade's edge stability leads to fewer rework cycles and predictable part tolerances, supporting efficient production runs.

Reliable seating and repeatable clamping for uptime

A secure interface between insert and tool body is essential for repeatable results; the geometry of this square insert matches Tungaloy milling systems and requires matching seat and clamp components. The square shape with a 0.8 mm corner radius and a 4.76 mm thickness ensures stable clamping and defined cutting positions. The insert's design — including a cylindrical hole with single-side countersink (40°–60°) — promotes correct orientation and reduces the risk of misassembly, contributing to shorter tool-change times and improved process reliability.

Productivity advantages and application scope

Designed for common milling tasks such as face, shoulder, slot, high-feed and contour milling depending on the tool family, this insert specialises in finishing workflows where surface quality and dimensional accuracy matter. The single-sided chipbreaker supports continuous cutting by controlling chip flow, while the sharp cermet edge minimises burr formation. When integrated into a matched milling body, the result is reduced cycle times and consistent part quality, making the component suitable for medium- to high-volume finishing where reproducibility is required.

FAQ

What materials is this insert suitable for?
The SCMT120408 NS9530 is specified as a finishing grade for steel; the uncoated NS9530 cermet is tailored to produce fine surfaces and low cutting forces in steel finishing applications.

Is this insert compatible with standard Tungaloy milling holders?
Compatibility requires matching the insert seat, geometry and clamping; the SCMT120408 is produced for Tungaloy milling systems and must be used with the corresponding tool body and clamp arrangement.

Does the insert come with a chipbreaker, and what is its function?
Yes — the insert features a single-sided chipbreaker, which controls chip formation during continuous cuts to support stable machining and reduce risk of recutting.

How does the uncoated cermet grade affect tool life and surface finish?
The uncoated cermet NS9530 offers a very sharp cutting edge for superior surface finish; it balances edge stability and wear resistance for finishing operations, helping to limit rework and maintain dimensional accuracy.

What are the key geometric values to check when replacing inserts?
Check the ISO designation 120408, the 12 mm size, 4.76 mm thickness and 0.8 mm corner radius, plus the hole and countersink style to ensure correct seating and orientation.
