SNGG120402-01 NS9530 – Square ISO turning insert for fine finishing, Tungaloy

The SNGG120402-01 is an ISO‑format square turning insert designed for external and internal turning, optimised for fine finishing of steels with continuous cuts and small depths of cut.

• ISO square turning insert, 12 mm size
• Uncoated cermet grade NS9530 for fine finishes
• 0° clearance angle for steady engagement
• 0.2 mm corner radius for controlled chip formation

Consistent fine finishing from a cermet grade built for low forces

The uncoated NS9530 cermet is engineered as a finishing grade for steel, combining a sharp cutting edge with reduced friction and low cutting forces. This results in improved part surface finish and reduced tendency for built-up edge during continuous turning. Cermet, a ceramic‑metal composite, maintains hardness at elevated temperatures while delivering a more stable cutting edge than many traditional grades; this makes the insert particularly suited to small depths of cut where surface quality and edge integrity are decisive. The concise geometry and sharp edge ensure reliable, repeatable finishes across batches.

Predictable fit and handling with ISO‑compliant geometry

The insert follows ISO guidance for indexable turning plates, offering a square insert form with a 12 mm size and 4.76 mm thickness, and a 0.2 mm corner radius that helps to control cutting forces and edge strength. The 0° clearance specification and a cylindrical hole facilitate secure clamping in appropriately matched holders. Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters gives a stable setup and consistent tool life. Selecting the correct chipbreaker and grade according to workpiece stability and machining strategy is essential to exploit the geometry fully.

Process efficiency and application guidance for turning operations

As a finishing insert for turning, the plate excels in external and internal turning where a sharp edge and steady chip control are required. The supplied chipbreaker style (01) is intended to suit continuous cutting where chips must be reliably managed to avoid surface damage. Integrating this insert into a workflow typically reduces rework due to improved first‑pass surface quality and predictable tool behaviour. For best results, pair the plate with a rigid holder and set cutting parameters consistent with finishing cuts; this approach promotes longer intervals between indexing and maintains component tolerances.

FAQ

Which materials are suitable for this insert?
The SNGG120402-01 in NS9530 is specified as a finishing grade for steel and is optimised for continuous cuts where a sharp edge and high surface quality are required.

How does the 0.2 mm corner radius affect machining?
A 0.2 mm radius provides a balance between edge strength and surface finish; the modest radius reduces cutting stress while still supporting fine external and internal finishing operations.

Is this insert compatible with standard ISO holders?
The plate follows ISO geometry conventions, but compatibility depends on holder form, clearance angle, tolerance class, fastening and thickness; matching these parameters ensures correct fit and clamping stability.

What role does the chipbreaker type 01 play?
Chipbreaker 01 is intended for controlled chip formation during continuous finishing cuts, improving chip flow and reducing the risk of surface damage on the workpiece.

Can this insert be used for roughing applications?
No; the NS9530 cermet is a finishing grade designed for low cutting forces and high surface quality rather than heavy material removal.
