TNMG 160408 AH120 – TNMG160408 AH120 Turning Insert by Tungaloy

The TNMG160408 AH120 is an ISO-standard triangular turning insert designed for external and internal turning operations in industrial machining.

• PVD-coated carbide for wear resistance
• Sharp cutting edge and process security
• ISO-standard geometry for holder compatibility
• Double-sided chipbreaker for economical use

Reliable cutting performance for continuous production

The insert delivers consistent material removal thanks to its PVD-coated carbide substrate and the AH120 grade, which combines wear resistance with high edge integrity. The sharp cutting edge and optimised chip control reduce the risk of built-up edge and unexpected breakouts, supporting predictable cycle times. For production environments where repeatability matters, this geometry contributes to stable tool life and fewer interruptions to machining sequences.

Secure clamping and straightforward holder matching

Compatibility with the clamping system is governed by the insert’s form, 0° clearance, tolerance class, fastening method, size and thickness. The ISO-standard triangular form and the cylindrical locating hole ensure reliable seating in a matching external holder or boring bar. Selecting the correct outer holder and the recommended backing/clip set with replacement screws secures the insert and maintains concentricity during turning cycles.

Material and coating engineered for longevity

Manufactured from a wear-resistant carbide grade and finished with a PVD coating (AH120), the plate is engineered to withstand abrasive and adhesive wear while preserving a fine cutting edge. The combination is particularly suited where a sharp cutting edge and process security are both required, balancing surface finish and edge life. The 0.8 mm corner radius gives a robust transition that reduces chipping risk on interrupted cuts.

Practical application guidance for process optimisation

Intended for general turning, the insert is suitable for both external and internal operations; the double-sided chipbreaker offers two usable edges, improving cost efficiency per index. Choose the chipbreaker and grade according to workpiece material and machining stability: smoother conditions benefit from smaller radii, while heavier interrupted cuts favour larger radii and stiffer setups. Integration into an ISO-based system is straightforward when holder form and thickness are matched.

FAQ

What workpiece materials are suitable for this insert?
The TNMG160408 AH120 insert is intended for a broad range of materials; the PVD-coated AH120 grade is optimised for wear resistance and is suitable when a sharp cutting edge and process security are required.

Is the insert reversible and how many cutting edges are available?
This triangular insert is double-sided with a chipbreaker on each usable face, offering multiple indexing options to extend effective tool life.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius provides a compromise between edge strength and surface finish, reducing the likelihood of chipping on interrupted cuts while still enabling good surface quality.
