SNMG120408 NS9530 Tungaloy indexable insert — ISO turning insert for finishing steel, uncoated cermet

The SNMG120408 NS9530 is an ISO‑standard turning insert designed for finishing steel, offering a sharp cutting edge, low cutting forces and a 0.8 mm corner radius for improved surface quality.

• ISO‑standard SNMG120408 form
• Uncoated cermet grade NS9530
• Sharp edge for superior surface finish
• Double‑sided chipbreaker, cylindrical hole

Consistent finishing with a low‑force cermet grade

The uncoated cermet grade NS9530 is formulated for finishing operations on steel, delivering a sharp cutting edge and reduced cutting forces. These properties result in a finer contact between tool and workpiece, which lowers vibration and improves repeatable surface finish in continuous cuts and shallow depths of cut. Cermet, a composite of ceramic and metallic binders, combines the wear resistance of ceramics with improved edge toughness, making it particularly suitable for high‑quality facing and light turning.

ISO compatibility and geometry for stable set‑ups

The SNMG120408 form is an ISO‑standard square insert with a 12 mm inscribed circle dimension, a 0.8 mm corner radius and a plate thickness of 4.76 mm; the included angle is 90° and the clearance angle is 0°. The insert features a cylindrical centre hole and a double‑sided chipbreaker, enabling two indexed cutting edges per insert. These standardised dimensions ensure straightforward compatibility with appropriately specified holders and boring bars; correct matching of holder form, clearance and tolerance class ensures secure clamping and minimises runout during turning.

Operational benefits for productive finishing

Using this indexable insert in finishing applications reduces the need for secondary passes by delivering a high‑quality first‑pass finish and consistent edge behaviour. The combination of the cermet grade and the geometry supports predictable tool wear and repeatable results across batches, which benefits cycle‑time planning and quality control. Selecting the correct chipbreaker and ensuring machine‑workpiece rigidity will extend insert life and maintain surface integrity; for unstable set‑ups, a different chipbreaker or increased support may be advised.

FAQ

What machining tasks suit this insert best?
The SNMG120408 NS9530 is optimised for finishing operations on steel, delivering a sharp cutting edge and low cutting forces for high surface quality in continuous, light cuts.

How many cutting edges are available per insert?
Due to the double‑sided chipbreaker and square plate form, the insert provides two indexable cutting edges, allowing rotation to a fresh edge when required.

Is the insert coated?
The NS9530 grade is an uncoated cermet; it is formulated to provide a fine cutting edge and superior surface finish without a coating layer.

Which holder characteristics must be checked for compatibility?
Compatibility is determined by holder form, clearance angle, tolerance class, clamping method, insert size and thickness; ensure the holder matches the SNMG120408 ISO form.

What are the key geometry values to consider during set‑up?
Important measurable values are the 12 mm inscribed circle, 4.76 mm plate thickness, 0.8 mm corner radius and the 90° included angle; these affect reach, depth of cut and insert clearance.
