SPMR120308 NS9530 ISO turning insert — finishing cermet by Tungaloy

A SPMR120308 NS9530 ISO turning insert engineered for finishing operations on steel, offering a sharp cutting edge for continuous cuts and fine surface finishes.

• Finishing uncoated cermet grade NS9530
• Low cutting forces for fine surface finish
• ISO SPMR120308 square 90° form, 0.8 mm radius
• Single-sided chipbreaker for continuous cuts

Delivering consistent finishing and superior surface quality

The insert is designed as a finishing grade made from cermet, optimised to produce excellent surface finishes with minimal follow-up work. The combination of a sharp cutting edge and low cutting forces reduces rubbing and smearing, which helps to maintain dimensional accuracy when performing light passes. For practical terms, cermet materials provide higher hot hardness and a more stable edge than conventional grades, making them particularly suitable for continuous turning where consistent surface quality is required.

Predictable chip control and process stability for turning

Equipped with a single-sided chipbreaker, this insert stabilises chip formation during steady cutting conditions, especially at small depths of cut. The chipbreaker geometry supports the generation of short, manageable chips in uninterrupted cuts and contributes to a reduced risk of built-up edge. As a result, the machining process benefits from improved tool life and less operator intervention, supporting higher throughput in production runs. The classification as an uncoated cermet emphasises its role in precision finishing rather than heavy roughing.

Compatibility and practical workshop advantages

Designed to the ISO specification and supplied in a square 90° form with a 0.8 mm corner radius, the insert integrates into standard ISO turning systems where form, clearance, tolerance class, fastening method, size and thickness match. The modest thickness and precise geometry allow easy seating in holders that accept SPMR120308-type plates, simplifying tooling logistics. For workshops aiming to streamline finishing processes, the insert offers a reliable option for steel machining where fine surface quality, repeatability and low cutting forces are priorities.

FAQ

What materials is this insert intended for?
The NS9530 finishing grade is formulated for machining Stahl (steel), providing a sharp edge and low cutting forces that favour high surface quality in steel turning operations.

How does the single-sided chipbreaker affect performance?
A single-sided chipbreaker on this insert promotes stable chip formation during continuous turning, reducing the risk of built-up edge and helping to maintain consistent surface finish and tool life.

Is the insert compatible with standard ISO holders?
Yes; the SPMR120308 design follows ISO specifications and requires a matching holder with the correct form, clearance angle, tolerance class, fastening method, size and thickness for secure clamping.

Which features support finishing operations specifically?
The combination of an uncoated cermet grade, a sharp cutting edge, and low cutting forces reduces rubbing and improves surface quality, making the insert particularly suitable for finishing passes and light feeds.
