TNGG110304-01 NS9530 triangular ISO turning insert by Tungaloy — uncoated cermet, 60° cutting angle

A TNGG110304-01 NS9530 indexable turning insert engineered for finishing operations on steel, offering a sharp cutting edge and low cutting forces for superior surface quality.

• Uncoated cermet for high surface finish
• Triangular ISO insert, 60° cutting angle
• 0° relief for continuous finishing cuts
• Suitable for external and internal turning

Enhanced surface quality for finishing cuts

The uncoated cermet grade NS9530 is formulated for finishing operations on steel, delivering a sharp cutting edge and reduced friction at the tool–workpiece interface. This results in lower cutting forces, which helps to limit workpiece distortion and to achieve consistent surface roughness even on sensitive geometries. For shops seeking predictable part quality, the finishing grade reduces secondary operations and supports tighter tolerances.

Clear guidance on compatibility and clamping

As an ISO-format triangular insert, compatibility with a toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness. The insert is a triangular shape with a 60° included angle, 0° relief, and a 0.4 mm nose radius, with a cylindrical locating hole for positive locating. In a standard system the insert is used together with a matching external holder or boring bar, an underlay/clamping set and replacement screws; this modular approach simplifies inventory management and reduces setup time.

Improve process stability and predictability

The uncoated cermet chemistry and the fine edge geometry make the grade particularly suitable for continuous cuts and small depths of cut, where a clean shear and steady chip formation are key. Selecting the correct chipbreaker (type 01 in this case) and adapting the holder rigidity to the application stabilises the cutting process and prolongs tool life. The combination of a stable cutting edge and low cutting forces contributes directly to higher first-pass yields and reduced rework.

Practical selection and application recommendations

For external and internal turning of steel components, choose this insert when surface finish and dimensional control are priorities. Match the chipbreaker and grade to the stock material, machining method and machine-tool rigidity for best results. Where interrupted cuts or heavy roughing are required, prefer more robust grades; for final passes and finishing, this insert delivers an efficient compromise between surface quality and tool economy.

FAQ

What machining operations is this insert intended for?
This insert is designed for turning operations; the NS9530 grade and triangular ISO form suit finishing passes on steel, for both external and internal turning.

How does the NS9530 cermet grade affect surface finish?
The NS9530 uncoated cermet provides a sharp cutting edge and reduced cutting forces, which together produce a finer surface finish and more consistent part quality when used for finishing cuts.

What holder features are required for correct fitment?
Fitment depends on holder form, clearance angle, tolerance class, fastening type, size and thickness; the insert uses a cylindrical locating hole and requires a clamping set compatible with ISO triangular inserts.

Can this insert be used for interrupted cutting?
This grade is optimised for continuous finishing and small depths of cut; for frequent interrupted cuts a tougher grade or alternative geometry is generally recommended.

Which manufacturers produce compatible holders and accessories?
Compatible holders and accessories are available from standard tooling suppliers; Metav Werkzeuge can advise on specific holder models that match the insert dimensions and clamping requirements.
