VNMG160408 AH120 Tungaloy indexable insert — rhombic ISO insert for turning with PVD-coated carbide

The VNMG160408 AH120 Tungaloy indexable insert is an ISO-standard rhombic turning insert designed for external and internal turning where sharp cutting edges and process security are required.

*Rhombic VNMG geometry, ISO 160408 compatible
*PVD-coated AH120 carbide for wear resistance
*0.8 mm corner radius for stable cutting edges
*Double-sided chipbreaker, hole for secure clamping

Reliable geometry for stable, repeatable turning results

The rhombic VNMG form provides a proven cutting geometry that balances strength and accessibility in a range of turning tasks. With the ISO designation 160408, compatibility with holders is determined by form, relief angle and thickness, which simplifies tool selection across standard toolholders. The insert’s rhombic shape and through-hole fastening ensure secure clamping and repeatable positioning, reducing setup variability and downtime. These geometric properties translate into fewer rejects and a steadier production flow.

Coating and grade engineered for abrasion and edge security

The AH120 grade is a PVD-coated carbide engineered to combine wear resistance with a sharp cutting edge. The coating improves adhesion and thermal stability while the carbide substrate resists catastrophic chipping under intermittent cuts. This combination delivers process security during continuous production, especially where consistent surface quality and predictable tool life are priorities. For shops aiming to optimise tool-change intervals, the AH120 grade offers a cost-effective balance between life and performance.

Edge preparation and micro-geometry for surface quality

A 0.8 mm corner radius provides a compromise between edge strength and achievable surface finish. The prepared edge reduces the risk of corner chipping when interrupted cuts occur and helps maintain dimensional tolerance on turned components. The insert’s 0° relief angle and the 35° orientation support versatile turning strategies, permitting stable cutting at varied depths and feeds while maintaining an even chip flow from the double-sided chipbreaker. These characteristics assist in achieving consistent part finish with minimal rework.

Practical selection and application guidance for production use

This ISO insert suits both external and internal turning operations where predictable performance is required. The PVD coating and grade choice make it appropriate for a broad material range; selection of the right chipbreaker and cutting parameters should be matched to the workpiece material and machine stability for optimum results. When replacing an insert, checking holder compatibility by form, thickness (4.76 mm) and hole style avoids setup errors. For integrated production processes, the insert’s repeatable seating and secure fastening reduce cycle interruptions and enhance overall throughput.

FAQ

What materials is this insert suited for?
The VNMG160408 AH120 Tungaloy indexable insert is designed for general turning tasks and, thanks to the PVD-coated AH120 grade, provides good wear resistance across a wide range of workpiece materials when cutting parameters are set appropriately.

How does the AH120 grade improve process security?
The AH120 grade combines a tough carbide substrate with a PVD coating to reduce wear and minimise edge chipping, delivering the process security required for longer tool life and consistent component quality with the VNMG160408 insert.

Is the VNMG160408 compatible with standard VNMG holders?
Yes — the ISO VNMG160408 designation ensures compatibility with holders designed for VNMG inserts; check form, thickness (4.76 mm), hole style and tolerance class to confirm correct fit for the chosen holder.

What cutting conditions benefit most from the 0.8 mm corner radius?
A 0.8 mm corner radius offers a suitable balance for finishing and medium turning operations where improved edge strength is needed to resist chipping while still maintaining a good surface finish with the Tungaloy VNMG insert.

Can the insert be used for internal turning?
The rhombic geometry and secure central clamping of the VNMG160408 make it suitable for selected internal turning tasks, provided the holder and access allow for the required approach angles and cutting conditions.
