VNMG160412 AH6225 — ISO turning insert by Tungaloy (35°, R1.2)

A VNMG160412 AH6225 ISO turning insert designed for external and internal turning, providing a sharp yet stable cutting edge for stainless steels

• PVD-coated carbide for enhanced wear resistance
• Universal grade optimised for stainless steels
• Rhombic form with 35° cutting angle
• Corner radius 1.2 mm and central cylindrical hole

Consistent cutting performance for stainless steels

The PVD‑coated AH6225 carbide provides a well balanced combination of a sharp cutting edge and edge stability tailored to medium turning conditions. This results in predictable tool life and consistent surface finish when machining stainless steels, even under changing cutting conditions. The coated grade helps reduce flank wear and increases process reliability, which in turn improves throughput and reduces scrap in routine production runs.

Geometry that reduces setup time and improves repeatability

The rhombic form and 35° cutting angle of this insert make it suitable for a broad range of external and internal turning tasks while the central cylindrical hole ensures secure locating and clamping in ISO tool holders. With a plate thickness of 4.76 mm and an insert size of 16 mm, the geometry is compatible with standard ISO holders; this compatibility simplifies tool changeover, reduces setup time and supports repeatable machining results across batches.

Application scope and chip control explained

Designed as a double‑sided insert with an integrated chipbreaker, this grade is aimed primarily at turning stainless steels under moderate cutting conditions. The chipbreaker geometry supports controlled chip formation, improving evacuation and minimising the risk of built‑up edge. For novice users: PVD coating is a thin, hard layer applied to the carbide that increases thermal and abrasive resistance without significantly altering the substrate toughness, making the insert suitable for demanding intermittent cuts.

Operational advantages and economic impact

Choosing a universal grade like AH6225 reduces the number of tool changes required across mixed stainless‑steel workpieces, which lowers tooling consumption and downtime. The 1.2 mm corner radius provides a balance between edge strength and profile fidelity, allowing for stable feeds and acceptable surface quality. In production terms, this translates to fewer interventions, more predictable insert life and an overall improvement in manufacturing productivity.

FAQ

What materials is this insert intended for?
The VNMG160412 AH6225 insert from Tungaloy is optimised for machining stainless steels, offering good edge stability and controlled chip formation during medium turning operations.

Can the insert be used for both external and internal turning?
Yes, the ISO geometry and rhombic form of this Tungaloy turning insert allow use in both external and internal turning applications when paired with a compatible ISO holder.

How does the AH6225 grade improve tool life?
The PVD‑coated AH6225 grade on this VNMG insert increases wear resistance and thermal stability, which helps maintain a sharper edge for longer and reduces flank wear under varying cutting conditions.

What does the 1.2 mm corner radius mean for surface finish?
A 1.2 mm corner radius on the VNMG160412 offers a compromise between edge strength and profile fidelity, enabling stable feeds and a consistent surface finish in medium cutting operations.

Is the insert reversible and how is it clamped?
The insert is double‑sided and features a central cylindrical hole for secure clamping in ISO holders; this supports economical use by allowing rotation to a fresh cutting edge.
