SNGG 120408 NS9530 — Tungaloy indexable turning insert, square 12 mm, 0° clearance

The SNGG120408-01 NS9530 is an ISO-format square indexable insert for turning, designed as a finishing grade for steel that prioritises surface quality and low cutting forces.

• Square 12 mm format, robust seating
• NS9530 uncoated cermet for finishing
• 0° clearance for sharp edge action
• Cylindrical hole for secure clamping

Achieve superior surface quality with a finishing cermet

The combination of an uncoated cermet grade and a sharp cutting geometry gives a measurable advantage when finishing steel components. The NS9530 grade is formulated for continuous cuts and small depths of cut, reducing the tendency for built-up edge and enabling consistently low cutting forces. That translates into improved part finish and fewer downstream grinding or polishing steps. For shops aiming to raise first-pass quality, this finishing insert supports predictable surface integrity with minimal compromise to cycle time.

ISO compatibility and secure clamping reduce setup time

Supplied in an ISO-design format, the insert is compatible with standard indexable turning holders when form, clearance angle, tolerance class, fastening method, size and thickness match. The square 12 mm plate size, 4.76 mm thickness and 0.8 mm corner radius ensure stable seating and repeatable positioning; the cylindrical hole enables secure clamping and simple replacement. Clear identification of these dimensions helps to select the correct external holder and reduces machine downtime caused by trial-and-error fitting, improving process reliability across batches.

Predictable finishing performance and efficient machining

As a dedicated finishing grade with chipbreaker 01, the geometry is tuned to produce short, controllable chips and an even cutting load at small depths. This yields consistent part-to-part results and reduces scrap rates in serial production. The cemented carbide substrate offers robust edge support for the fine cutting edge, producing high-quality surfaces while keeping cutting forces low; the result is an efficient balance between tool life and finish quality that supports profitable batch machining of steel components.

FAQ

What steels is this finishing grade best suited to?
The NS9530 cermet grade is optimised for finishing operations on steel; the SNGG120408-01 insert is intended where low cutting forces and high surface quality are required.

How does the 0° clearance affect cutting behaviour?
A 0° clearance produces a very sharp edge action that lowers cutting forces and promotes a fine surface finish; the trade-off is that correct holder geometry and rigidity must be ensured for stable performance.

Which holders are compatible with this ISO insert?
Compatibility is determined by insert form, clearance angle, tolerance class, fastening, size and thickness; the ISO-format designation SNGG120408-01 guides selection of a matching external holder.

What is the role of chipbreaker 01 on this insert?
Chipbreaker 01 is designed for finishing conditions, producing short, controllable chips and maintaining an even cutting load under small depths of cut.

How does the uncoated cermet grade influence tool life and finish?
The uncoated cermet NS9530 supports a very sharp cutting edge and reduced built-up edge formation, improving surface finish; tool life is optimised for finishing cycles rather than heavy roughing.
