TNMG 160402 AH6225 Tungaloy turning insert — PVD‑coated carbide, 60° triangle

A TNMG 160402 AH6225 Tungaloy turning insert engineered for external and internal turning operations, offering a sharp yet stable cutting edge optimised for mid‑range machining of stainless steels.

• PVD‑coated carbide grade AH6225
• Sharp, stable cutting edge for stainless steels
• 60° triangular geometry, 0.2 mm nose radius
• Double‑sided chipbreaker with cylindrical hole

Consistent performance in stainless‑steel turning

The insert is a PVD‑coated carbide grade developed to balance edge sharpness and durability for challenging materials. The coating enhances wear resistance and reduces built‑up edge when machining stainless steels, while the substrate retains toughness for interrupted cuts. This combination results in a more stable process, fewer tool changes and predictable tool life, which supports leaner production and improved net machining time.

ISO compatibility and secure mounting for efficient tool changes

Designed to the ISO model series for turning insert geometries, the component matches standard holders when form, clearance angle, tolerance class, fastening method, size and thickness align. The triangular 60° form and the cylindrical hole provide straightforward clamping in compatible TNMG toolholders, enabling quick index changes. Clear identification of size and tolerances minimises setup time and ensures repeatable positioning on the toolpost.

Practical machining guidance for reliable results

For external and internal turning, select a chipbreaker and the AH6225 grade according to material condition and fixturing stability. The double‑sided chipbreaker supports controlled chip formation under variable cutting conditions, reducing the risk of tangling and improving surface finish. When working with slender parts or intermittent cuts, favour conservative feeds and keep cutting parameters within the mid‑range recommended for PVD‑coated carbides to maintain edge integrity and component quality.

Coating, grade and operational economy

The AH6225 designation denotes a PVD‑coated carbide composition optimised for a wide coverage of stainless‑steel applications and changing conditions. The coating assists in thermal resistance and friction reduction at the cutting zone, which can translate into longer edge life and lower tooling costs per part. By combining an industrially established grade with ISO form standards, this insert supports consistent productivity and easier inventory management across series production.

FAQ

Is this insert suitable for stainless steels?
Yes. The TNMG 160402 AH6225 Tungaloy turning insert is a universal grade optimised for stainless‑steel machining, combining a sharp cutting edge with stability for mid‑range conditions.

How does the insert mount to a holder?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the TNMG form and cylindrical hole are intended for standard TNMG ISO holders and secure clamping.

What does AH6225 indicate?
AH6225 denotes a PVD‑coated carbide grade formulated for good wear resistance and reliable chip control under changing conditions, offering a compromise between sharpness and edge life.

Which chipbreaker should be chosen for roughing?
Select the chipbreaker suited to the material and process stability; the double‑sided chipbreaker on this insert supports controlled chip formation for many stainless‑steel roughing and finishing tasks.

How is the designation TNMG160402 interpreted?
The ISO designation identifies the insert form and size series; detailed values such as nose radius 0.2 mm, plate thickness 4.76 mm and 60° geometry are provided in the technical data above.
