TNMG 160408 NS9530 – Indexable turning insert for finishing, Tungaloy

TNMG 160408 NS9530 is an ISO-standard triangular indexable insert optimised for finishing operations in steel, offering a sharp cutting edge and a low cutting-force geometry for continuous cuts.

• Triangular ISO insert TNMG 160408
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge and low cutting forces
• Double-sided chipbreaker, 0° rake, cylindrical hole

Deliver consistent, high-quality surface finish in steel turning

The uncoated cermet grade NS9530 combines high hardness and thermal stability to deliver a sharp cutting edge that reduces built-up edge and lowers cutting forces. This results in consistently improved surface finish on turned steel components, especially in finishing passes with small depths of cut and continuous chip flow. Compared with conventional carbide grades, a cermet finishing grade often yields longer intervals between rework and less dependence on aggressive cutting fluids, which supports process efficiency.

Designed geometry and clamping for stable, repeatable machining

The triangular shape with a 60° included angle and the 16 mm inscribed circle place the insert within common ISO holder families, enabling straightforward integration into standard turning systems. A thickness of 4.76 mm, a corner radius of 0.8 mm, and a cylindrical hole ensure secure clamping and repeatable indexability. The double-sided chipbreaker offers two usable cutting edges per side, increasing economy per index and allowing simple rotation for renewed geometry. Compatibility with external holders or boring bars depends on holder form, clearance angle, tolerance class, fastening and insert size.

Practical process advantages and recommended applications

Engineered for external and internal turning in steel, this finishing insert excels in continuous cuts and light feed, producing dimensionally accurate and smooth parts with reduced power draw and vibration. The composition and geometry make it particularly suitable for fine finishing where a low cutting force and sharp edge are required. For system assembly, pair the insert with a matching ISO external holder or boring bar, a suitable shim/clamp set and replacement screws to maintain clamping integrity and repeatable results across production batches.

FAQ

What materials is this insert suited to?
The TNMG160408 NS9530 is designed as a finishing grade for steel; the uncoated cermet NS9530 performs best in continuous turning of steel components.

Can the insert be used on both external and internal turning operations?
Yes, the ISO-format triangular insert is suitable for both external and internal turning when mounted in a compatible external holder or boring bar.

How does the double-sided chipbreaker affect tool economy?
The double-sided chipbreaker on this insert allows multiple usable edges per index, improving economy per insert and simplifying edge rotation for renewed cutting geometry.

What clamping and holder considerations are important?
Secure clamping relies on matching holder form, tolerance class, fastening method and insert thickness (4.76 mm); the cylindrical hole supports reliable repeatability when assembled correctly.
