TNMG 160404 AH905 Tungaloy turning insert — PVD‑coated carbide, 60° geometry

The TNMG160404 AH905 is a triangular ISO turning insert designed for reliable external and internal turning where a sharp edge and process security are required

• PVD-coated carbide grade AH905
• Triangular ISO insert, 16 mm size
• 0.4 mm corner radius for precise turning
• Double-sided chipbreaker with cylindrical hole

Consistent cutting performance for general turning

The PVD coating applied to the AH905 grade enhances wear resistance and helps maintain a sharp cutting edge over extended running times. This combination of carbide substrate and thin PVD layer is especially suited to operations that demand both edge robustness and a consistent surface finish. For general turning tasks, the reduced flank wear provided by the coating translates into fewer indexings and more parts machined per insert, which supports higher productivity and predictable cycle times.

Secure clamping and economical indexing

As an ISO‑standard insert with a cylindrical hole and triangular geometry, the component is compatible with common external holders and boring bars when form, clearance angle, tolerance class, clamping method, size and thickness match. The double‑sided chipbreaker and the 16 mm size allow the insert to be indexed for four usable cutting edges, enabling cost‑effective use and reduced tool change frequency. The 4.76 mm plate thickness provides stable engagement in the pocket, promoting repeatable seating and improved vibration control during heavy cuts.

Geometry and grade tuned to practical machining needs

The 60° included angle together with a 0.4 mm radius produces a balance between cutting‑edge strength and surface quality: a small radius supports fine finishing, while still resisting chipping under moderate depth of cut. The 0° relief specification is part of the ISO geometry family and must be matched to the chosen holder; correct seat and clamp settings ensure the expected process security. The AH905 grade has been developed for high reliability in turning, offering stable chip control and resistance to edge breakout where a sharp edge is required.

FAQ

What materials is this insert designed for? The TNMG160404 AH905 insert, a PVD‑coated carbide solution from Tungaloy, is intended for general turning applications; material selection for best results should consider the workpiece and cutting data.

How many cutting edges are available per insert? With its triangular form and double‑sided chipbreaker, the insert offers multiple indexable cutting edges, allowing economical use and fewer tool changes for production turning.

How does the AH905 grade perform compared with standard grades? AH905 is formulated to combine wear resistance and edge toughness; the grade is PVD‑coated to extend life while preserving a sharp cutting edge under typical turning conditions.

What is the purpose of the 0.4 mm corner radius? A 0.4 mm radius balances improved surface finish with adequate edge strength; it reduces the risk of chipping compared with smaller radii while still supporting fine finishing cuts.

Does the insert fit all ISO holders with the TNMG pocket? Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; correct matching of these parameters ensures secure seating and repeatable performance with the TNMG160404 AH905 insert.
