TNMG160408 AH120 TNMG turning insert – PVD-coated carbide, 60° triangle, Tungaloy

TNMG160408 AH120 Tungaloy turning insert for external and internal turning in standard ISO holders, designed for stable chip formation and secure clamping

• PVD-coated carbide for high process reliability
• Sharp cutting edge and wear-resistant AH120
• Double-sided triangular geometry with cylindrical hole
• 0.8 mm corner radius, 60° included angle

Proven performance and measurable efficiency for turning operations

The combination of a PVD-coated carbide substrate and the AH120 grade gives a balance of wear resistance and fracture toughness that improves tool life under varied cutting conditions. The coating reduces adhesion and enhances thermal stability, which translates into fewer tool changes and steadier cycle times. With a sharp cutting edge and optimised chip control, the insert supports higher metal removal rates while maintaining dimensional consistency, so production runs remain predictable and economical.

Simple integration with ISO systems and clear mounting requirements

As an ISO-compliant, triangular indexable insert, the TNMG160408 is compatible with standard holders when form, relief angle, tolerance class, clamping method, size and thickness match. The cylindrical hole and precise tolerances facilitate secure clamping and repeatable positioning in the holder. Thickness of 4.76 mm and a plate size of 16 mm provide rigidity for a wide range of external and internal turning tasks; the double-sided design enables reindexing to a fresh cutting edge, improving cost efficiency per edge.

Geometry tuned for surface quality and edge stability

The 0.8 mm corner radius and 60° included angle deliver a good compromise between edge strength and surface finish: the radius absorbs occasional cutting shocks, while the acute geometry allows accurate profiling and finishing passes. The double-sided triangular layout yields multiple usable edges, reducing downtime for insert changes. For operations where a fine surface and consistent tolerance are priorities, this geometry supports stable cutting forces and improved repeatability.

Select chipbreaker and grade to match workpiece and process stability

Intended for turning (external and internal), the insert performs best when the doppelseitig chipbreaker and the AH120 grade are chosen according to the workpiece material, cutting method and machine stability. The system comprises the ISO turning insert, a matching external holder or boring bar, and the required clamp or shim set plus fastening screws. For less familiar applications, consultation on chipbreaker selection and cutting parameters ensures the right compromise between surface finish and tool life.

FAQ

What applications suit this insert best?
This insert is intended for turning applications — both external and internal — where ISO-standard inserts are used; the AH120 grade and PVD coating support stable, productive machining.

How is the TNMG160408 mounted in the holder?
The TNMG160408 uses a cylindrical hole and standard clamp or screw systems; compatibility depends on the holder’s form, relief angle and tolerance class to ensure secure and repeatable clamping.

Can the insert be reindexed and how many edges are usable?
The triangular, double-sided design allows multiple reindexes; each side provides fresh cutting edges, improving per-edge economy and reducing tool changes.

Which advantages does the AH120 grade provide?
AH120 offers a wear- and breakage-resistant performance with a sharp cutting edge and good process reliability, making it suitable where edge integrity and consistent results are required.

Does the geometry affect surface finish?
Yes — the 0.8 mm corner radius and 60° included angle balance edge strength with surface quality, supporting fine finishing and steady cutting forces.
