TNMG 160404 NS9530 Turning insert (ISO) by Tungaloy — uncoated cermet, 0° clearance

TNMG 160404 NS9530 is a triangular ISO turning insert designed for finishing operations in steel, offering a sharp cutting edge and a double-sided chipbreaker for improved chip control.

• Uncoated cermet grade NS9530
• Sharp edge for fine finishing
• Triangular 16 mm inscribed circle
• 0° clearance angle, cylindrical hole

Precision finishing for steel components

The combination of an uncoated cermet cutting material and a finely honed geometry makes this insert particularly effective where surface quality matters. The chosen grade, NS9530, maintains a sharp cutting edge under continuous cutting conditions, which reduces cutting forces and helps achieve tighter surface tolerances. For finishing passes with small depths of cut, the lower cutting resistance contributes directly to reduced vibration and improved dimensional stability, translating into fewer rework steps and a more predictable process.

Seamless integration with ISO turning systems

This indexable plate conforms to ISO dimensions and is intended for installation in ISO-compatible external holders or boring bars; compatibility is governed by form, clearance angle, tolerance class, fastening method, size and thickness. The insert’s triangular shape with a cylindrical hole and standard thickness simplifies changeover and reduces inventory complexity. Using a correctly matched holder and clamping set ensures secure seating and repeatable positioning, which shortens setup time and supports consistent part-to-part accuracy on batch runs.

Durable edge performance and efficient chip control

For fine finishing of steel, the uncoated cermet offers excellent edge retention and dependable wear resistance, leading to stable machining over longer tool life in finishing applications. The double-sided chipbreaker provides reliable chip control in both orientations, helping to maintain a steady material flow and minimising the risk of surface damage. These characteristics support higher overall productivity by extending the usable life of each indexed position and reducing unscheduled tool changes.

Practical guidance for best results

Use the insert primarily for continuous turning operations with modest feed and depth of cut to exploit its strengths in surface quality. The 0° clearance in combination with the 60° included angle suits precision finishing profiles, while the 0.4 mm corner radius provides a balance between an unobtrusive tool mark and adequate edge strength for fine passes. When selecting the chipbreaker and grade, match the NS9530 to steel workpieces and choose cutting data that favour steady, continuous cuts rather than aggressive material removal to preserve surface integrity.

FAQ

What materials is this insert best suited for?
The TNMG 160404 NS9530 Tungaloy turning insert (SKU 6997704-Tungaloy) is optimised for finishing operations in steel, where the uncoated cermet grade provides a sharp edge and low cutting forces for improved surface finish.

How does the insert mount in a tool system?
Mounting requires an ISO-compatible external holder or boring bar; compatibility for the TNMG 160404 NS9530 is determined by form, clearance angle, tolerance class, fastening method, size and thickness.

Is the chip control suitable for finishing applications?
Yes — the double-sided chipbreaker on the TNMG 160404 NS9530 insert ensures consistent chip control in both orientations, aiding stable material flow and protecting surface quality during fine cuts.

Can this insert be used for interrupted cutting?
The NS9530 grade and geometry are optimised for continuous finishing cuts; while occasional interrupted cuts are possible, frequent interruptions may shorten edge life and affect surface quality.
