SPGM 090304 NS9530 Wendeplatten - Tungaloy

Take advantage of a precise finishing solution that combines an uncoated cermet cutting material with a low cutting force geometry and a secure clamping design. The result is consistent surface quality and longer edge life in continuous turning of Stahl. Order the SPGM090304 NS9530 insert directly via Metav Werkzeuge or ask our consultants if needed.

SPGM 090304 NS9530 Tungaloy indexable insert for turning — square, 11° relief

The SPGM090304 NS9530 is a square ISO indexable turning insert designed for fine finishing of Stahl in external and internal turning operations.

• Uncoated cermet for fine finishing
• Square insert, 09 size, 0.4 mm corner radius
• 11° relief angle for stable cutting
• 3.18 mm plate thickness for rigidity
• Cylindrical hole for secure clamping

Precise finishing performance for continuous turning

The uncoated cermet grade NS9530 is engineered for finishing cuts on Stahl, offering a sharp cutting edge with low cutting forces and excellent surface quality. The fine-grain cermet substrate reduces built-up edge formation during continuous, light-depth passes, which leads to more consistent part surfaces and fewer rework cycles. In practice, this means the insert supports higher reproducibility on finishing operations and helps maintain dimensional tolerances with minimal thermal influence.

Stable clamping and geometry for predictable tool life

A combination of a square plate form, a 0.4 mm corner radius and a 3.18 mm plate thickness delivers mechanical stiffness and predictable edge behaviour. The 11° relief angle reduces flank contact, lowering friction and heat generation at the cutting edge. The centre cylindrical hole provides secure location in standard ISO turning holders, while the single-sided chipbreaker is configured for controlled chip formation in finishing regimes. These attributes reduce vibration and support repeatable cutting conditions across batches.

Application guidance and productivity benefits

Intended primarily for external and internal turning of Stahl, the insert suits finishing and light-precision machining where surface integrity is critical. Select the chipbreaker and grade to match the workpiece material, machining stability and feed rates — this will optimise chip control and maximise edge life. Practical advantages include shorter inspection times due to improved surface finishes, and reduced downtime from fewer insert changes during continuous runs. If further specification advice is required, technical details and process recommendations are available to aid integration into existing turning cycles.

FAQ

What machining operations is this insert intended for?
The SPGM090304 NS9530 insert is intended for external and internal turning, primarily for finishing operations on Stahl.

How does the NS9530 grade affect surface finish?
The NS9530 uncoated cermet provides a sharp cutting edge with low cutting forces, which improves surface quality and reduces the risk of built-up edge during continuous finishing passes.

Which holder features are required for correct fitment?
Compatibility is determined by insert form, relief angle, tolerance class, clamping method, size and thickness; the square SPGM090304 locates via its cylindrical hole in ISO turning holders designed for 09-sized plates.
