SNGG120408-01 NS9530 ISO indexable turning insert by Tungaloy — finishing grade for turning

The SNGG120408-01 NS9530 is a square ISO-format indexable insert designed for turning operations, optimised as a finishing grade for steel with a sharp edge, low cutting forces and excellent surface finish.

• ISO square insert SNGG120408-01
• Uncoated cermet NS9530 finishing grade
• Sharp edge for low cutting forces
• 0.8 mm corner radius, 4.76 mm thickness

Precision finishing tailored for steel turning

The finishing-grade NS9530 composition delivers consistently low cutting forces and a sharp cutting edge, making it ideal for applications where surface integrity is critical. As an ISO-format indexable insert, the component supports controlled, continuous cuts and small depths of cut, which in turn reduces vibration and improves repeatability. The resulting benefit is fewer rework cycles and a predictable surface finish, measured in improved Ra values when compared with generic grades. The square geometry with a defined 90° cutting face contributes to dimensional control on external and internal turning operations.

Clear compatibility and straightforward mounting

Compatibility with toolholders depends on form, clearance, tolerance class, fastening method, size and thickness; the insert matches standard ISO turning holders when these parameters are observed. The design includes a cylindrical hole for secure clamping and a standard thickness of 4.76 mm, which simplifies inventory management across ISO systems. Technical clarity around these parameters reduces setup time at the machine and helps maintain stable tool projection, which is essential for finishing tasks where minimal deflection is required.

Productivity gains through predictable tool behaviour

By selecting a finishing-grade, uncoated cermet insert with 0.8 mm corner radius, the process benefits from low heat generation and consistent chip formation in steel applications, while the defined chipbreaker designation 01 supports manageable swarf control in continuous cuts. The combination of a sharp edge and the material characteristics of the grade reduces feed sensitivity and enables higher part-to-part consistency. For production environments aiming to raise first-pass yield and lower manual finishing effort, this insert provides a demonstrable improvement in throughput without compromising surface quality.

FAQ

Which materials is this insert intended for?

The grade NS9530 is an uncoated cermet finishing grade intended primarily for steel; the SNGG120408-01 insert is optimised for continuous cutting and small depths of cut where high surface finish is required.

How is holder compatibility determined for this insert?

Compatibility is determined by form, clearance (freiwinkel), tolerance class, fastening, size and thickness; the insert fits standard ISO turning holders that accept the SNGG120408-01 format and a 4.76 mm plate thickness.

What chipbreaker and cutting style suit this insert?

The insert carries chipbreaker designation 01 and is intended for finishing operations with continuous chips and small depths of cut to achieve stable chip flow and a fine surface finish.

What are the key dimensional values to check before mounting?

Key values are a 12 mm plate size, 4.76 mm thickness, 0.8 mm corner radius and a 90° plate angle; the hole is cylindrical for secure clamping.

Is this insert suitable for roughing operations?

No; the SNGG120408-01 NS9530 is a finishing-grade insert designed for low cutting forces and high surface quality rather than the heavy material removal typical of roughing.
