TNMG 160408 AH6225 — Turning insert (ISO 160408) for stainless steels by Tungaloy

The TNMG160408 AH6225 is an ISO-standard triangular turning insert engineered for external and internal turning, offering a balanced mix of edge sharpness and stability for changing machining conditions.

• PVD-coated carbide AH6225 for stainless steel
• Sharp, stable cutting edge for medium cuts
• ISO-standard triangular insert, 16 mm size
• Double-sided chipbreaker with cylindrical hole

High productivity through consistent cutting performance

The TNMG160408 insert pairs a PVD-coated carbide substrate with a cutting geometry that promotes stable chip formation and repeatable results in stainless-steel turning. The combination of a sharp cutting edge and a double-sided chipbreaker reduces the need for frequent edge changes and helps maintain process stability under variable conditions. This leads to fewer interruptions on the shop floor and a more predictable machining cycle time, supporting efficient batch and single-part production alike.

Clear guidance on holder compatibility and setup

Compatibility with a tool holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness; the ISO-standard designation removes much of the guesswork when selecting a matching external holder or boring bar. The insert’s 0° clearance and triangular form provide multiple indexing positions, while the cylindrical hole secures reliable clamping in standard clamping systems. Correct clamping and the appropriate support pad or screw set are decisive for achieving the advertised repeatability and surface quality.

Grade design and material suitability for demanding stainless applications

The AH6225 grade is a universal choice for stainless steels, engineered to deliver a sharp yet robust cutting edge for medium-depth cuts and mixed machining conditions. The PVD coating enhances wear resistance and chemical stability at elevated interface temperatures, improving edge life where workhardening and built-up edge can be problematic. Selecting this grade helps reduce rework and delivers a smoother part finish with less manual intervention.

System-level efficiency and economical tool handling

As part of an ISO insert system, the triangular plate integrates into a straightforward tooling setup: insert, compatible external holder or boring bar, support pad/clamp kit and replacement screws. Using a 16 mm ISO insert with a 0.8 mm corner radius facilitates a balance between edge strength and profile accuracy, while double-sided indexing extends usable cutting length. This systematic approach supports planned maintenance, predictable tool consumption and transparent cost-per-component calculations.
