TNMG160412 AH6225 Tungaloy — ISO indexable turning insert, 1.2 mm radius, PVD-coated carbide

The TNMG160412 AH6225 is an ISO triangular indexable insert engineered for external and internal turning applications, optimised for stainless steel and medium machining tasks.

• ISO triangular insert, 60° geometry
• PVD-coated carbide AH6225 for stainless steel
• 1.2 mm corner radius for robustness
• Double-sided chipbreaker with cylindrical hole

Predictable cutting performance for stainless steel

The PVD‑coated AH6225 grade provides a balance between a sharp cutting edge and edge stability, making it suitable for medium cutting of stainless steel in changing conditions. The combination of a controlled chip‑forming geometry and a double‑sided chipbreaker reduces the risk of built‑up edge, improving surface finish and process stability. The 1.2 mm corner radius increases edge strength for interrupted cuts and modest depth of cut regimes, while the PVD layer enhances wear resistance without compromising the initial sharpness of the carbide substrate.

Smooth integration into ISO tool systems for fast changeovers

As an ISO‑standard insert, the triangular shape with a 60° included angle and a cylindrical‑hole configuration ensures compatibility with a wide range of external holders and boring bars. Compatibility is determined by form, relief angle (0°), tolerance class, fastening method, nominal size (16 mm) and plate thickness (4.76 mm). The system typically comprises an ISO turning insert, a matching external holder or boring bar, a support shim/clamp set and replacement screws; selecting components that match the insert’s geometry simplifies setup and reduces spindle downtime.

Practical selection guidance for reliable productivity

For medium‑duty turning where variable conditions occur, choose the chipbreaker and grade to match workpiece material and process stability. The AH6225 grade is designed for consistent performance on stainless steel, offering a useful compromise between wear life and edge sharpness. Where cycle stability is critical, the 1.2 mm corner radius and the insert’s robust geometry increase repeatability and lower scrap risk. The insert’s double‑sided design enables indexing to fresh edges, extending tool life and reducing tooling cost per part over small to medium production runs.

FAQ

Which materials is this insert best suited for? The TNMG160412 AH6225 Tungaloy indexable insert is optimised for machining stainless steel and performs well in medium cutting conditions where a sharp but stable edge is required.

How does the chipbreaker affect performance? The double‑sided chipbreaker on this insert improves chip control and reduces the tendency for built‑up edge, supporting stable surface finish and repeatable cycles during turning operations.

Can the insert be indexed to a fresh cutting edge? Yes, the triangular, double‑sided design allows rotation and indexing to additional cutting edges, extending effective tool life for the insert supplied as TNMG160412 AH6225.

What should be checked for holder compatibility? Holder compatibility depends on form, relief angle (0°), tolerance class, fastening and plate thickness; matching these parameters to the TNMG160412 geometry ensures secure clamping and correct cutting geometry.

What is the effect of the 1.2 mm corner radius? A 1.2 mm corner radius increases edge strength and resistance to chipping, improving robustness during interrupted cuts and promoting consistent dimensional results.
