TNMG160404 AH120 ISO turning insert for Turning — PVD-coated carbide, 0.4 mm radius (Tungaloy)

The TNMG160404 AH120 is an ISO‑standard triangular indexable insert designed for external and internal turning, offering a sharp cutting edge and enhanced process stability for general turning applications.

• ISO triangular insert TNMG 160404
• PVD-coated carbide AH120 for wear resistance
• Double-sided chipbreaker for process security
• 0.4 mm corner radius, 60° cutting angle

Consistent performance and longer tool life

The TNMG160404 AH120 insert combines a PVD‑coated carbide substrate with a wear- and fracture-resistant grade to maintain a sharp cutting edge under demanding conditions. The AH120 grade is engineered to balance flank wear resistance and edge toughness, resulting in a predictable tool life that supports batch production and short-cycle machining. Together with the double-sided chipbreaker, this construction ensures controlled chip formation and reduced rework, which helps maintain part tolerances and decreases downtime in serial turning operations.

Quick integration and predictable set‑up

As an ISO standard insert, compatibility with toolholders depends on form, relief angle, tolerance class, mounting and thickness rather than proprietary interfaces. The triangular shape with a cylindrical hole and 60° geometry enables straightforward clamping in many common external holders and boring bars. The 4.76 mm thickness provides increased rigidity for interrupted cuts, while the 0° relief angle specification supports a secure fit and consistent seating. These characteristics reduce set‑up iterations and make the insert a practical choice for workshops that require rapid tool changes and reproducible machining results.

Application fit and machining advantages

Designed primarily for turning, the insert performs well where a sharp edge and stable process are required. The 0.4 mm corner radius offers a compromise between edge strength and surface finish: it reduces the risk of edge chipping on heavy cuts while still allowing acceptable surface quality on finishing passes. The PVD coating improves resistance to adhesive and abrasive wear, increasing the interval between indexings. For operations that demand repeatability and efficient chip evacuation, this configuration supports both roughing and medium finishing tasks with reduced risk of unexpected tool failure.

FAQ

What is the primary application of this insert?
The TNMG160404 AH120 insert from Tungaloy is intended for external and internal turning operations where a sharp cutting edge and reliable process stability are required.

Which holder types are compatible with this ISO insert?
Compatibility is determined by form, relief angle, tolerance class, mounting, size and thickness; the TNMG160404 fits standard ISO triangular holders and many common boring bars with a cylindrical‑hole clamping interface.

How does the AH120 grade affect machining?
The AH120 grade offers a balanced combination of wear resistance and edge toughness, improving tool life and reducing the likelihood of edge chipping during general turning tasks.

What benefits does the PVD coating provide?
The PVD‑coated carbide surface enhances resistance to adhesive and abrasive wear, supports higher process reliability and contributes to longer intervals between indexings.

How does the 0.4 mm corner radius influence results?
A 0.4 mm corner radius increases edge strength for heavier cuts while still allowing a reasonable surface finish, offering a versatile compromise for mixed roughing and finishing applications.
