TNMG160404 NS9530 TNMG turning insert for finishing of steel — Tungaloy

A TNMG160404 NS9530 insert designed to ISO standards for precision turning; optimised for fine finishing of steel components in continuous cuts.

• ISO TNMG triangular insert, 16 mm size
• Uncoated cermet grade NS9530
• Sharp edge for superior surface finish
• Double-sided chipbreaker, cylindrical hole

High-quality finishing with reduced cutting forces

The uncoated cermet NS9530 delivers a sharp cutting edge and inherently low cutting forces, which translates into a measurable improvement in machined surface quality. As a finishing grade, this insert is engineered for continuous cuts and small depths of cut, so waviness and workpiece distortion are minimised. The result is fewer rework cycles and a predictable surface roughness—advantages that support tighter tolerances and more efficient downstream processing.

Stable geometry for reliable indexable performance

The triangular geometry with a 16 mm inscribed circle and a corner radius of 0.4 mm provides a stable seating and predictable engagement with the workpiece. The insert features a double-sided chipbreaker and a cylindrical hole for positive clamping; the 60° included angle ensures familiar toolpath geometry for standard TNMG holders. Because the compatibility with a holder depends on form, relief angle, tolerance class, clamping type, size and thickness, the ISO-standard dimensions simplify the selection process and reduce setup time while enabling quick index changes to restore cutting performance.

Practical application notes and material match

Designed primarily for external and internal turning, the grade excels in finishing operations on steel thanks to its combination of a finely honed edge and low cutting forces. Match the NS9530 grade and the double-sided chipbreaker to the workpiece stability and the intended feed to avoid edge chipping during interrupted cuts. For mixed production or variable stability, select an appropriate holder and clamping set to maintain repeatable results; Metav Werkzeuge can supply the correct seating pads and screws to complete the system. The engineering behind the insert supports consistent batch-to-batch performance and facilitates predictable tool changes.

FAQ

Which materials is this insert intended for? The NS9530 grade is formulated for finishing on steel; the TNMG160404 NS9530 insert from Tungaloy is optimised to deliver high surface quality on continuous steel cuts.

Is this insert suitable for both external and internal turning? Yes, the ISO TNMG shape and the insert geometry make it appropriate for both external and internal turning applications when paired with the correct holder.

How does the double-sided chipbreaker affect performance? The double-sided chipbreaker allows two indexings per insert edge arrangement, improving cost efficiency and ensuring consistent chip control with the NS9530 finishing grade.

What should be checked to ensure holder compatibility? Verify the holder matches form, relief (0° in this case), tolerance class, clamping type, insert size and thickness to ensure correct seating of the TNMG160404 NS9530 insert.

Can the insert be re-indexed to restore cutting performance? Yes, the triangular geometry and double-sided design permit re-indexing to present a fresh cutting edge and maintain productivity.
