CNMG 120402 NS9530 turning insert by Tungaloy — finishing cermet, 0.2 mm radius

A CNMG 120402 NS9530 indexable insert designed for precision turning of steel, offering a finishing-grade uncoated cermet for low cutting forces and excellent surface quality.

• Cermet finishing grade NS9530
• Sharp cutting edge for fine surface finish
• 0.2 mm corner radius, 80° insert geometry
• Double-sided chipbreaker, cylindrical hole

Deliver consistently improved surface finish with a cermet finishing grade

The uncoated cermet grade NS9530 is formulated for finishing operations on steel, delivering a finishing edge that keeps cutting forces low and reduces vibration. This results in measurable improvement in surface integrity and dimensional stability when making continuous passes with small depths of cut. For shops seeking predictable, high-quality finishes, the combination of a sharp cutting edge and a robust substrate supports longer intervals between regrinds and less rework.

Predictable geometry for reliable process planning

Manufactured to ISO dimensions, the insert features an included angle of 80° and a clearance angle of 0°, which together stabilise cutting forces and direction of chip flow. The modest 0.2 mm corner radius balances edge strength and the ability to achieve fine surface textures. Because compatibility with the holder is determined by form, clearance, tolerance class, fastening, size and thickness, using ISO-standardised inserts simplifies fixture selection and inventory management while enabling repeatable cycle-time planning.

Application advantages and recommended cutting conditions

This indexable solution is optimised for external and internal turning where continuous cuts and small depths of cut are common. The continuous cuts recommendation aligns with the uncoated cermet’s strengths: a sharp edge for excellent finish and low built-up edge tendency on steels. The double-sided chipbreaker and the rhombic plate form with a cylindrical hole allow cost-effective indexing and simple clamping arrangements, which supports higher productivity in finishing operations without sacrificing component quality.

Practical integration into the production cell

As part of a system comprising an ISO insert, a matching external holder or boring bar, shims and clamping sets, the insert is straightforward to install and index. The rhombic plate shape and the cylindrical hole facilitate stable location and secure fastening. For teams planning tool lists or retrofitting turning centres, this insert reduces set-up variability thanks to standardised dimensions and well-understood handling procedures, aiding faster process qualification and drift-free production runs.

FAQ

What materials is this insert intended for? This Tungaloy CNMG 120402 NS9530 insert is intended primarily for turning steel, offering a finishing-grade solution that performs best in continuous cutting on steels.

Is the cutting edge coated? The grade NS9530 is an uncoated cermet, providing a sharp edge for superior surface finish rather than a coating-based wear layer.

How is compatibility with a toolholder ensured? Compatibility is determined by insert form, clearance angle, tolerance class, fastening, size and thickness; check holder specifications against the ISO dimensions of the insert before fitting.

Can both sides of the insert be used? The double-sided chipbreaker and rhombic plate form allow the insert to be indexed and used on both faces before replacement.

For which operations is this insert recommended? The insert is recommended for external and internal turning where fine surface quality and small depths of cut are required, particularly in continuous cutting applications.
