TNMG160408 NS9530 ISO triangular turning insert for turning – Tungaloy

TNMG160408 NS9530 is a 60° ISO triangular indexable insert designed for precision external and internal turning, optimised for fine finishing on steel with a low cutting-force approach

• ISO-standard 60° triangular geometry
• NS9530 uncoated cermet for fine finishing
• Double-sided chipbreaker for stable chip control
• 0.8 mm corner radius for superior surface finish

Achieve consistent fine finishes with low cutting forces

The grade NS9530, an uncoated cermet, is developed for finishing operations where a sharp cutting edge and low cutting forces matter. This insert combines a small 0.8 mm corner radius with a 60° geometry to deliver reproducible surface quality on steel during continuous cuts and small depth-of-cut operations. The result is less rework, fewer passes to tolerance and a measurable improvement in component appearance and dimensional consistency. The material behaviour of cermet supports stable cutting at finishing speeds, reducing burr formation and improving dimensional control.

Stable chip control and predictable tool life

Equipped with a double-sided chipbreaker, the insert supports predictable chip formation across a range of finishing feeds. The 0° rake and optimised chipformer promote tight chips and reduce the risk of built-up edge, which in turn prolongs effective cutting time and reduces quality variation. The double-sided design also offers economical indexability: two usable cutting edges per side extend the usable life before replacement is required. For production environments seeking repeatable cycles and reduced tool change frequency, this geometry offers a reliable balance between performance and economy.

ISO compatibility for quick integration into existing toolholders

As an ISO-standardised triangular insert, the plate is compatible with holders that match the plate’s form, clearance angle, tolerance class, fastening and thickness. The system typically comprises an ISO turning insert, a matching external holder or boring bar, a clamping pad or clamp set and replacement screws. Because the insert follows ISO norms, setup time is reduced and inventory management is simplified: holders and spares are interchangeable within the same ISO family, helping to streamline spindle changeovers and reduce downtime in mixed production runs.

Targeted use: finishing steel in external and internal turning

This insert is intended primarily for finishing tasks on steel where surface quality and dimensional control are priorities. Its NS9530 cermet composition and fine edge geometry support continuous cutting and small feed operations typical of final-pass machining. In practice, the insert performs well on turned components requiring tight surface finish specifications, such as shafts, bushes and precision mating surfaces. Select the appropriate holder stability and feed strategy to exploit the insert’s strengths and avoid excessive overhang to maintain edge life and part quality.

FAQ

Which materials is this insert best suited for?
The TNMG160408 NS9530 is formulated as a finishing grade primarily for steel; its NS9530 cermet composition delivers low cutting forces and excellent surface quality on steel workpieces.

Can the insert be indexed and reused on both sides?
Yes. The insert features a double-sided chipbreaker and a triangular form that allow multiple indexing positions, offering economical edge usage before replacement.

What holder characteristics are needed for correct use?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and plate thickness; use a suitably rigid external holder or boring bar matched to the ISO plate family for best results.

How does the NS9530 cermet compare to conventional carbide for finishing?
NS9530 cermet provides a sharper edge and improved surface finish in finishing cuts, often with lower cutting forces than some cemented carbides; it is particularly effective in continuous cutting and small depth-of-cut scenarios.

What are the key dimensions and geometry to note when ordering?
Key specifications include the ISO code 160408, 16 mm size, 4.76 mm thickness, 0.8 mm corner radius and 60° triangular geometry, as listed in the technical data.
