TNMG160408 AH120 turning insert – Tungaloy

TNMG160408 AH120 is a triangular, ISO‑standard indexable insert designed for robust external and internal turning in industrial applications.

• ISO TNMG geometry, triangular insert
• PVD-coated carbide, grade AH120
• Double-sided chipbreaker for consistent chips
• 0.8 mm corner radius, 60° included angle

Consistent edge quality for secure machining

The triangular indexable insert delivers a stable cutting edge that supports reliable chip control and repeatable results in series production. The PVD coating on the carbide substrate provides wear resistance and helps maintain a sharp edge, which reduces the risk of built-up edge and unexpected edge chipping. With a 0.8 mm corner radius and a 60° included angle, this geometry balances edge strength and cutting performance, making it suitable for operations that require a clean surface finish while maintaining robust tool life. The combination of coating and substrate ensures consistent removal rates and predictable regrind cycles.

Optimised process stability and longer tool life

The AH120 grade is engineered for a compromise between toughness and wear resistance, giving improved resistance to flank wear and occasional interruptions in the cut. The double-sided chipbreaker design supports controlled chip formation on both orientations, extending usable life by enabling indexable re-use of the opposite cutting edge. These characteristics contribute directly to higher process stability: fewer tool changes, less downtime, and more predictable cycle times. For production environments where reproducibility and low variation matter, the insert’s specification reduces machining risk and supports cost-efficient throughput.

Straightforward fitment and broad ISO compatibility

Fitting into standard ISO turning systems, the insert features a cylindrical hole for secure clamping and a plate thickness of 4.76 mm, ensuring correct seating and repeatable clamping forces in compatible holders. The insert’s 16 mm size and ISO designation simplify tooling choices across many holders and boring bars, limiting the need for bespoke adapters. Technical teams benefit from clear interchangeability: the insert matches common external and internal turning set-ups and integrates into a system comprising suitable holders, clamping sets and replacement screws for quick reconditioning on the shop floor.

FAQ

What machining tasks is this insert intended for?
The TNMG160408 AH120 insert is designed for external and internal turning, offering a balance of edge strength and surface quality for routine turning operations.

How does the AH120 grade affect performance?
The AH120 grade combines wear resistance and toughness; in the TNMG160408 it supports a sharp cutting edge while delivering consistent tool life under varying turning conditions.

Can the insert be indexed to use multiple cutting edges?
Yes, the triangular geometry and double-sided chipbreaker allow indexing of unused edges, increasing the number of available cutting edges per insert and improving overall economy.

What are the key dimensions to check when selecting a holder?
Verify the ISO designation 160408, 16 mm size, 4.76 mm thickness and the 60° included angle to ensure correct fitment and clamping with compatible holders.
