SNMG 120402 NS9530 turning insert – uncoated cermet, 0.2 mm radius (Tungaloy)

A SNMG120402 NS9530 indexable turning insert for finishing operations on steel, designed for continuous cuts and fine surface quality.

• Finishing-grade uncoated cermet
• Sharp cutting edge for fine surface finish
• 0.2 mm corner radius for precision
• Double-sided chipbreaker, square form

Precision finishing and how the grade makes the difference

The combination of an uncoated cermet cutting material and a sharp cutting edge delivers low cutting forces and superior surface quality on steel. Cermet grades like NS9530 are optimised for finishing: they maintain edge stability during continuous cuts and reduce built-up edge formation, which converts directly into fewer rework cycles and improved part aesthetics. For shops aiming to raise component finish without sacrificing cycle stability, this indexable insert provides a predictable, repeatable result.

Compatibility with ISO holders and why dimensions matter

Designed to the ISO standard SNMG120402 form, the insert’s geometry and a 4.76 mm thickness permit straightforward pairing with compatible external holders and boring bars. The square plate format and the cylindrical hole require the correct backing pad and clamp set to achieve repeatable clamping accuracy. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters reduces chatter and optimises tool life in production environments.

Practical benefits on the shop floor

A 0.2 mm corner radius balances edge strength with the ability to produce tight radii and fine profiles; it suits low‑depth finishing passes and delicate operations where surface quality is critical. The double‑sided chipbreaker aids chip control in continuous turning, reducing the risk of entanglement and improving swarf evacuation. Together, these features support higher process stability and fewer stoppages in repetitive production work.

System setup and recommended use cases

Implementing this insert within a complete system — insert, suitable external holder or boring bar, backing pad/clamp set and replacement screws — ensures consistent performance. The geometry supports both external and internal turning when mounted on appropriate tooling; selecting the chipbreaker and grade to match the workpiece material and machining stability is essential for optimal results. The 90° cutting angle and 0° clearance provide a neutral geometry for common finishing tasks, while the robust substrate supports repeatable performance under steady cutting conditions.

FAQ

What materials is this grade suited for?
The NS9530 finishing grade is formulated for steel machining; the SNMG120402 NS9530 Tungaloy insert offers low cutting forces and a sharp edge designed to produce high surface quality on steel workpieces.

Can the insert be used for both external and internal turning?
Yes, the SNMG120402 geometry is suitable for both external and internal turning when paired with the appropriate ISO‑compatible holders and boring bars.

How does the 0.2 mm corner radius affect machining?
A 0.2 mm radius provides a compromise between strength and edge definition, enabling fine finishing passes and accurate profile generation while maintaining adequate edge life.

Is a coated grade preferable for interrupted cuts?
For interrupted cutting, a more wear‑resistant or coated grade may be preferable; the uncoated NS9530 excels in continuous finishing cuts but may not offer the same robustness under heavy interruptions.

Which components complete the tooling system for reliable clamping?
A matching external holder or boring bar, a backing pad or clamp set and the correct replacement screws complete the system; compatibility depends on insert form, thickness and fastening style.
