VNMG 120408 NS9530 — VNMG120408E-TF finishing turning insert (ISO 120408) by Tungaloy

VNMG120408E-TF NS9530 is a rhombic ISO turning insert designed for finishing operations on Stahl, offering a sharp cutting edge and low cutting forces for continuous cuts and small depths of cut

• Uncoated cermet NS9530 for fine finishing
• Rhombic ISO VNMG 120408 form, 35° angle
• 0.8 mm corner radius for superior surface finish
• Cylindrical hole, 4.76 mm thickness for secure clamping

Superior surface quality with low cutting forces

The insert combines an uncoated cermet grade (NS9530) with a finely honed cutting edge to deliver consistently high surface finishes on Stahl components. The low built-up edge tendency of the grade reduces friction at the tool–workpiece interface, which in turn lowers cutting forces and dampens vibration. For finishing cycles with small depths and continuous cuts, this behaviour yields repeatable dimensional accuracy and minimises rework, making the solution particularly efficient for serial production where surface integrity matters.

Robust ISO compatibility and secure clamping

Built to the ISO 120408 specification in a rhombic form, the insert ensures reliable fitment in standard VNMG holders; compatibility is dictated by form, free clearance angle (0°), tolerance class, fastening method, plate size 12 and thickness 4.76 mm. The cylindrical hole and standard fixing geometry provide stable seating under moderate cutting forces, which supports consistent tool life and predictable process windows. Specifying the correct holder geometry and torque for the clamping screw is recommended to preserve cutting-edge life and machining accuracy.

Improved productivity through optimised chip control

The TF chipbreaker is tailored for finishing on Stahl, producing short, controllable chips at low feeds and small depths of cut. This chip form reduces the risk of surface damage and eases chip evacuation in close-tolerance setups. The insert’s 0.8 mm corner radius balances edge strength with the need for fine surface finishes; the combination reduces the likelihood of micro-chipping while maintaining a refined profile on turned parts. For operations prioritising throughput and quality, this configuration supports longer uninterrupted cycles and fewer tool changes.

Practical handling and integration in workshop workflows

The insert is supplied as part of a simple system: ISO turning insert, matching external holder or boring bar, and standard clamping hardware. The carbide substrate delivers the rigidity required for finishing applications, while the compact geometry facilitates quick index rotations and replacements. When integrating the insert into a production cell, select a holder that matches the form and tolerance class, and pair the grade with stable workholding to exploit the low cutting-force behaviour. If additional machining data or holder recommendations are required, technical advice is available to ensure seamless adoption.

FAQ

What is the primary application of this insert?
The VNMG120408E-TF NS9530 is intended for finishing turning operations, particularly continuous cuts and small depths on Stahl.

Which holder type matches this insert?
Compatibility depends on the ISO VNMG form, 0° free clearance and thickness; use a matching VNMG external holder or boring bar specified for ISO 120408.

How does the TF chipbreaker affect machining?
The TF chipbreaker on this Tungaloy insert generates short, controllable chips at low feeds, improving surface quality and chip evacuation during finishing.

Is this insert suitable for interrupted cuts or heavy roughing?
The NS9530 grade and 0.8 mm radius are optimised for finishing; heavy roughing and highly interrupted cuts are outside the recommended application range.

What makes NS9530 different from coated grades?
NS9530 is an uncoated cermet designed for sharp edges and low cutting forces, prioritising surface finish over the wear resistance typically offered by coated grades.
