TNMG 160404 AH6225 indexable insert for turning — Tungaloy

The TNMG160404 AH6225 is an ISO-indexed triangular insert designed for external and internal turning, offering a universal grade optimised for machining stainless steels.

• PVD-coated carbide AH6225
• Optimised for stainless steel machining
• 0.4 mm corner radius for fine detail
• 60° triangular insert geometry
• Double-sided chipbreaker, with centre hole

Consistent edge performance for varied stainless-steel work

The PVD-coated AH6225 grade is designed as a universal solution for machining stainless steel, combining a sharp cutting edge with sufficient edge stability for medium-duty operations. The PVD coating improves wear resistance and helps maintain surface finish over longer tool life, while the carbide substrate ensures predictable cutting behaviour under varying conditions. This balance reduces the need for frequent insert changes, supporting steady productivity and reliable process results.

Geometry that supports precision and repeatability

A 60° triangular form with a 0.4 mm corner radius provides a precise option for turning tasks that require controlled corner definition and dimensional accuracy. The insert’s 4.76 mm thickness and 0° relief contribute to rigidity at the cutting zone, aiding in vibration damping and consistent chip formation. Compatibility with ISO-format holders depends on matching the insert form, clearance angle, tolerance class, fastening and size, ensuring reproducible clamping and repeatable part quality when the correct holder and clamp set are used.

System advantages that save time and materials

The double-sided chipbreaker design and the central cylindrical hole enable economical, double-index usage and secure fixation in the pocket, which lowers tooling cost per edge and minimises machine downtime. As part of an ISO-indexed system—insert, external holder or boring bar, shim/clamp set and spare screws—the component allows fast indexing and straightforward inventory management. The combination of PVD-coated carbide and an optimised chipbreaker supports stable chip control and improved surface finish, making the insert suitable for typical shop-floor turning operations.

FAQ

What materials is this insert suited for? The AH6225 grade is intended primarily for stainless steel machining; the TNMG 160404 AH6225 insert is a universal choice for medium cutting conditions on such alloys.

How does the 0.4 mm corner radius affect results? A 0.4 mm corner radius gives finer corner definition and improved dimensional control while still offering sufficient edge strength for typical turning operations.

Is the insert reversible and easy to index? Yes, the insert is double-sided and can be indexed to present a fresh cutting edge, reducing tooling expenses and downtime.

What holder compatibility should be checked before use? Ensure holder compatibility by matching the insert form, clearance/freedom angle, tolerance class, fastening method, size and thickness to achieve secure clamping and repeatable results.

Does the PVD coating improve tool life? The PVD-coated carbide construction of the AH6225 grade enhances wear resistance and helps retain surface finish under varying conditions, contributing to predictable tool life.
