SCMT 070204 NS9530 Tungaloy turning insert — finishing grade, uncoated cermet

The SCMT070204-24 NS9530 is an ISO‑indexable turning insert for finishing of steel, designed for external and internal turning where a sharp cutting edge and low cutting forces are required.

• ISO-indexable square insert 07 size
• Uncoated cermet for high surface finish
• 0.4 mm corner radius for precise finishing
• Cylindrical hole with single-sided countersink

Achieve consistently superior surface finish with a finishing cermet

This insert uses an uncoated cermet grade NS9530, optimised for finishing operations on steel. The material combines ceramic hardness with metallic toughness, which gives a sharp cutting edge and reduced adhesion tendency; the outcome is a high surface finish with low cutting forces under continuous cutting and small depths of cut. For process planners this means lower spindle loads and more predictable part quality when a smooth finish is the key criterion.

Secure mounting and ISO compatibility for predictable tool changeovers

The insert is ISO-indexable in a square form with size 07 and an insert thickness of 2.38 mm, ensuring compatibility with standard clamping systems when the holder matches the form, 7° clearance angle, tolerance class, fastening method, size and thickness. The centre hole is cylindrical with a single-sided countersink (40°–60°) to ensure reliable seating and repeatable indexing. Specifying holders and clamp sets that match these geometric parameters shortens setup time and reduces variability across tool changes.

Small corner radius and geometry tailored for finishing efficiency

A 0.4 mm corner radius provides the balance between edge strength and fine contour definition, making the insert suitable for fine passes and detail work. The geometry, together with the finishing grade, supports continuous cuts and modest depths of cut where surface quality and dimensional control are priorities. Choosing the matching chipbreaker and the 24 chipbreaker variant allows for controlled chip formation when machining stable setups; the overall package improves process stability and contributes to predictable tool life and part consistency.

FAQ

Is this insert suitable for finishing steel?
The SCMT070204-24 NS9530 Tungaloy insert is a finishing grade developed for steel; its uncoated cermet NS9530 provides a sharp edge and low cutting forces for superior surface quality.

Which toolholders fit this insert?
Compatibility depends on the holder matching the square form, 7° clearance angle, tolerance class, fastening method, size (07) and thickness (2.38 mm); selecting holders designed for ISO‑indexable SCMT inserts ensures secure mounting.

What is the hole and countersink configuration?
The insert has a cylindrical hole with a single‑sided countersink (40°–60°), which provides stable seating and repeatable indexing in standard clamp systems.

For which cutting conditions is this grade recommended?
This finishing grade is intended for continuous cutting and small depths of cut, where low cutting forces and a fine surface finish are required.

How does the corner radius affect the finish?
A 0.4 mm corner radius offers a balance between edge strength and fine contouring, promoting precise finishes and controlled contact stress on the workpiece.
