WNMG 080408 AH6225 ISO turning insert — trigon, PVD-coated cemented carbide (for turning) — Tungaloy

The WNMG080408-SDM AH6225 is an ISO-standard turning insert designed for external and internal turning, offering a sharp yet stable cutting edge optimised for medium machining of rostfreier Stahl.

• PVD-coated carbide grade AH6225
• Optimised SDM chipbreaker for chip control
• Trigon insert with 80° cutting edge
• 0.8 mm corner radius for precision turning

Consistent performance from a PVD-coated universal grade

The AH6225 grade is a PVD-coated cemented carbide designed as a universal solution for machining rostfreier Stahl, providing a balance between edge sharpness and toughness. This combination permits steady cutting performance under changing conditions and moderate cutting parameters, reducing the need for constant insert changes. Compatibility with tooling is determined by insert form, relief angle, tolerance class, fastening and plate thickness, ensuring predictable integration into established turning setups.

Controlled chips and improved surface quality in turning operations

The SDM chipbreaker and trigon geometry support reliable chip formation and evacuation, which helps to prevent re-cutting and improves surface finish in both external and internal turning applications. The 80° main cutting edge, together with the 0° relief angle, contributes to stable engagement and predictable cutting forces, resulting in fewer rejects and less post-process finishing for better economic efficiency.

Fast replacement and secure clamping for uninterrupted production

With an ISO-standard format and a cylindrical hole for positive location, the insert offers straightforward mounting and repeatable positioning in compatible holders. The plate thickness of 4.76 mm and the 0.8 mm corner radius deliver a compromise between rigidity and fine-edge capability, allowing reliable tool life while maintaining dimensional accuracy. This reduces downtime for index changes and supports stable batch production.

Robust coating and edge stability for longer tool life

The PVD coating enhances wear resistance under mixed-production conditions and contributes to a consistent cutting edge during medium-duty operations. Longer tool life and stable edge geometry lower the total processing cost by minimising regrinds and replacements. The grade's design aims at efficient chip control and dependable results across a wide range of rostfreier Stahl alloys.

FAQ

What materials is this insert best suited for?
The WNMG080408-SDM AH6225 insert is optimised for machining rostfreier Stahl and performs well in medium-duty turning where a sharp but stable cutting edge is required.

How does the SDM chipbreaker benefit production?
The SDM chipbreaker on this trigon insert improves chip control and evacuation, reducing the risk of built-up edge and enhancing surface finish when the WNMG080408-SDM AH6225 is used in turning operations.

Which holder parameters determine compatibility?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; these factors should match the ISO-standard insert seat of the chosen holder.

What does a 0.8 mm corner radius mean for machining?
A 0.8 mm corner radius provides a balance between edge strength and surface quality, offering better durability than a very small radius while still enabling precise turning for dimensional accuracy.

Is the insert easy to index and replace during production?
The ISO-standard design and the cylindrical locating hole allow repeatable positioning and straightforward indexing, which helps to minimise tool-change time and supports continuous production with the Tungaloy insert.
