SNMG 090308 NS9530 – Tungaloy indexable turning insert (ISO 090308) for turning

The SNMG090308-TM NS9530 is an ISO-standard indexable turning insert designed for finishing operations on steel, delivering a sharp cutting edge and low cutting forces.

ISO‑standard square insert, 90° cutting geometry
Uncoated cermet NS9530 for high surface finish
TM chipbreaker, suited to continuous cuts

Precision finishing for external and internal turning

The SNMG090308-TM from Tungaloy is engineered as a finishing grade for steel, optimised for continuous cuts and small depths of cut to deliver a superior surface finish. The uncoated cermet substrate NS9530 provides a sharp, wear-resistant cutting edge that reduces friction and cutting forces, which in turn helps to minimise tool vibration and improves dimensional consistency. Compatibility with the clamping system is ensured by standardised form, clearance angle, tolerance class, fastening method, size and thickness, so the insert integrates smoothly into existing turning tool systems.

Key geometry and material benefits explained

This indexable insert is a square 09 format with a 90° included angle, a 0.8 mm corner radius and a plate thickness of 3.18 mm; the insert is supplied with a cylindrical hole and a 0° clearance angle, forming a robust seating for positive clamping. The NS9530 cermet grade is uncoated and intended specifically for finishing: it combines edge sharpness with thermal stability to maintain profile accuracy during fine feeds. The TM chipbreaker geometry promotes controlled chip formation for steady evacuation in continuous turning, reducing the risk of built-up edge and improving process repeatability.

Production gains and recommended application scope

In precision turning operations the insert contributes to higher throughput by shortening post-process finishing and limiting rework, thanks to consistent surface quality and stable wear behaviour. The combination of low cutting forces and effective chip control often permits more predictable cycle times on automated lathes and turning centres. The insert is suitable for both external and internal turning tasks where fine surface integrity is required; selection of the correct holder and clamp set is advised to match the insert form, tolerance class and thickness for optimal performance. Shops focused on finishing, high repeatability and long tool life will find the combination of geometry and NS9530 material advantageous.
