SNGG 120408 NS9530 indexable turning insert for turning by Tungaloy

the SNGG120408-01 NS9530 indexable turning insert designed for finishing steel in external and internal turning, featuring a square geometry and a cylindrical hole for secure clamping

• ISO‑standard square insert
• NS9530 cermet for superior surface finish
• Sharp edge for low cutting forces
• Suitable for continuous cutting and small depths

Precision geometry for stable, repeatable clamping

The ISO‑standard square geometry with a cylindrical hole provides a secure and repeatable seating in compatible toolholders. The design conforms to ISO series requirements, so compatibility depends on holder form, clearance angle, tolerance class, fixing method, size and thickness; this ensures predictable positioning and minimal movement under cutting forces. The 4.76 mm thickness and the square form give the insert rigidity during finishing cuts, reducing vibration and improving dimensional consistency.

NS9530 cermet grade delivers high surface quality

The NS9530 uncoated cermet grade is optimised for finishing operations in steel, combining a sharp cutting edge with excellent wear resistance to produce a high surface finish. The material composition offers low cutting forces and reliable edge integrity during continuous cutting and small depths of cut, which reduces the need for secondary finishing. For applications where a fine surface and minimal burr formation are priorities, this grade provides tangible productivity benefits.

Application guidance and tooling choices for best results

Selection of the correct chipbreaker and holder is essential: the insert is supplied with chipbreaker 01 and a corner radius of 0.8 mm, attributes that support smooth chip formation in finishing passes. The listed 0° clearance angle suits specific holder geometries and should be matched by the external or boring bar assembly to ensure the intended effective rake and contact conditions. Where stability is limited, prioritise rigid clamping and minimal overhang to maintain the sharp edge and consistent performance.

Production advantages and process reliability

Incorporating this insert into finishing operations results in lower rework rates and predictable tool life, translating into fewer stoppages and better throughput. The ISO coding and standard dimensions make stock management straightforward, while the combination of the NS9530 cermet and the square form supports consistent surface quality across batches. For machining centres and turning shops seeking repeatable finishing performance, the component contributes to stable, economic production.

FAQ

Is this insert suitable for finishing steel components?
The SNGG120408-01 NS9530 insert is a finishing grade specifically formulated for steel; the NS9530 cermet provides a sharp edge and low cutting forces to achieve a high surface finish.

Which holder details must be matched for correct fitment?
Compatibility is determined by holder form, clearance angle, tolerance class, fixing method, insert size and thickness; ensure the toolholder accepts the SNGG120408-01 ISO geometry and accommodates a 12 mm square insert with a cylindrical hole.

Can the insert be used for internal turning as well as external turning?
Yes, the insert is intended for both external and internal turning applications, provided a suitable boring bar or internal holder that matches the 0° clearance and square geometry is used.

What cutting conditions is the insert optimised for?
The NS9530 cermet grade and chipbreaker 01 are optimised for continuous cutting and small depths of cut typical of finishing operations, where surface quality and low cutting forces are required.

Which product identifiers should be referenced when ordering or specifying the insert?
Reference the ISO designation SNGG120408-01, manufacturer article number 6997815 and SKU 6997815-Tungaloy when ordering or specifying this Tungaloy indexable turning insert.
