VNMG160412 AH6225 indexable turning insert — PVD-coated carbide for stainless steel (Tungaloy)

The VNMG160412 AH6225 is a PVD-coated carbide, ISO‑standard indexable insert designed for precision external and internal turning, offering a sharp yet stable cutting edge suitable for medium machining and changing conditions.

• PVD-coated carbide grade AH6225
• Designed for stainless steels
• ISO VNMG160412 rhombic form
• Double-sided chipbreaker for versatility

Consistent surface quality and predictable tool life

The AH6225 grade combines a PVD-coated surface with a carbide substrate to deliver a sharp cutting edge that resists wear under variable conditions. For shops focused on reproducible results, this configuration reduces process variation by maintaining edge geometry during medium-duty cuts. The coating improves thermal and abrasive resistance, which contributes to steadier surface finishes on stainless steels and lowers the frequency of unscheduled insert changes. As a result, cycle time stability improves and setup downtime is minimised.

Fast integration into ISO holders and secure clamping

Designed to the ISO VNMG160412 outline, this ISO VNMG160412 rhombic insert fits common turning holders when form, clearance, tolerance class, attachment and size match. The insert features a rhombic profile with a cylindrical hole for positive location and secure fastening, a nominal corner radius 1.2 mm and a 0° clearance specification. The listed 35° lead angle supports efficient cutting geometry for external and internal passes, enabling compatibility with standard tool systems and simplifying toolroom logistics when replacing worn edges.

Productivity through versatile chip control and economical use

A double-sided chipbreaker extends usable edges and enhances chip formation across a range of feeds and depths, reducing the need for constant parameter changes. The carbide base gives robust mechanical support for the cutting edge, while the PVD finish adds tribological benefits that lower build‑up and edge degradation. For production environments the combination of ISO turning inserts and this grade supports predictable interchangeability, enabling cost-conscious operations to plan insert usage and inventory with confidence.
