• PVD-coated carbide AH6225 for stainless steel
• Double-sided insert with cylindrical hole
• Stable cutting edge for medium machining

Consistent performance on stainless steel with PVD‑coated carbide

The combination of the AH6225 grade and a PVD‑coated carbide substrate delivers a balance between edge sharpness and wear resistance ideal for a range of stainless steel applications. The coating reduces adhesion and improves thermal stability, which helps maintain a sharp cutting edge under changing cut conditions; the result is more consistent surface finish and predictable tool life. For medium machining, this translates into reliable chip formation and fewer unscheduled tool changes, improving process stability.

Predictable fit and repeatable geometry in ISO tool systems

The triangular 60° shape with a 0.4 mm corner radius and a 0° clearance angle provides a predictable engagement and a defined contact geometry with the workpiece. Compatibility with holders is governed by form, clearance angle, tolerance class, fastening, size and thickness; the insert’s ISO designation and the presence of a cylindrical hole simplify selection of the correct clamping system. A standardised fit enables repeatable seating and indexing, which supports consistent part quality across consecutive tool changes.

Economic machining through double‑sided design and clear system integration

This insert is double‑sided, offering two usable cutting edges per side where applicable, which reduces tooling cost per edge and shortens tool change frequency. The insert sits within a modular system that typically includes a matching outer holder, shim or clamp set, and replacement fixing screws; this system approach ensures secure clamping and safe performance at recommended cutting parameters. Selecting the appropriate chipbreaker and grade for the material and machine stability will further enhance productivity and reduce cycle time.

FAQ

What materials is this insert suited for?
The AH6225 grade is designed primarily for stainless steel applications; the TNMG 160404 insert performs well in medium machining of such materials.

How does the PVD coating benefit cutting performance?
The PVD‑coated carbide reduces adhesion and increases thermal resistance, which helps preserve the cutting edge and improve surface finish under varying cutting conditions.

Can the insert be used on both sides before disposal?
Yes, the double‑sided design provides additional cutting edges, allowing rotation or indexing to a fresh edge to extend usable life.

What determines compatibility with a holder?
Compatibility is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters ensures correct seating and clamping.

Is the TNMG 160404 suitable for internal turning operations?
The TNMG 160404 format and geometry are suitable for both external and internal turning, provided a compatible toolholder and the correct chipbreaker are selected.
