SCMT 120408 NS9530 indexable milling insert — cermet finishing grade, 0.8 mm corner radius (Tungaloy)

A SCMT 120408 NS9530 indexable insert engineered for finishing operations in milling, designed to fit Tungaloy milling systems where insert seat, geometry and cutter body are matched.

• Cermet finishing grade NS9530
• Sharp cutting edge for fine surfaces
• Square 90° geometry for shoulder milling
• Single-sided chipbreaker, with hole

Consistent finishing performance with reduced cutting forces

The uncoated cermet grade NS9530 is formulated for finishing steel, combining a sharp cutting edge with reduced cutting forces to produce superior surface quality. In continuous-cut scenarios and small depths of cut, the material’s edge stability and low cutting resistance help to lower vibration and improve the reproducibility of the machining result. This performance benefit translates into fewer rework cycles and a reliable surface finish when precision is required.

Secure clamping for stable machining and repeatability

Designed as part of a matched milling system, the insert’s square 90° geometry and cylindrical hole with single-side countersink (40°–60°) ensure correct seat location and clamp engagement. Correct mating between insert seat, geometry and cutter body is essential: it provides a repeatable reference, minimises micro‑movement under load and supports longer consistent life of the cutting edge. The result is predictable behaviour in batch production and improved process stability.

Practical application range and productivity benefits

This grade is intended primarily for finishing tasks such as face, shoulder and slot milling, as well as contour work when used in the appropriate cutter family. The combination of low cutting forces and a 0.8 mm corner radius supports delicate edge transitions and fine surface finishes while maintaining adequate robustness for medium-duty runs. For operations where dimensional accuracy and surface integrity influence downstream processes, the insert helps to increase first-pass yield.

System considerations and economical use

Supplied as part of the Tungaloy insert system, the component integrates with clamping screws, shims and cutter bodies to form a complete tooling solution. Because an insert’s performance depends on the whole assembly, selecting the correct cutter body and clamp torque is crucial for maximising tool life and achieving consistent part quality. Where tool families offer different geometries, choosing the matching combination reduces the risk of accelerated wear and supports repeatable production outcomes.

FAQ

What applications is this insert best suited for?
The SCMT 120408 NS9530 indexable insert is optimised for finishing steel in face, shoulder and slot milling where a fine surface finish and low cutting forces are required.

Is the insert coated?
No, the NS9530 is supplied as an uncoated cermet; this enhances edge sharpness for finishing on steel while offering consistent surface quality.

How does the 0.8 mm corner radius affect results?
A 0.8 mm corner radius balances edge strength with the ability to produce fine surface transitions; the radius helps avoid premature chipping while maintaining good finish quality.

Can this insert be used in non‑Tungaloy cutter bodies?
The insert will perform only when the insert seat, geometry and cutter body are technically compatible; the SCMT 120408 must be used in suitably designed milling systems that match its dimensions and clamping style.

Which SKU identifies this item for ordering?
Order reference: SKU 6998492-Tungaloy (Manufacturer SKU: TUN6998492) for the SCMT 120408 NS9530 indexable insert.
