TNMG 160404 AH6225 indexable turning insert – PVD-coated carbide, 0.4 mm radius (Tungaloy)

TNMG160404 AH6225 is a triangular indexable insert for external and internal turning, designed for medium machining of stainless steel with a sharp yet stable cutting edge.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• Triangular 16 mm size, 0.4 mm corner radius
• Double-sided chipbreaker with cylindrical hole

High-performance cutting for stainless steel with longer tool life

The insert combines a PVD-coated surface with a carbide substrate in grade AH6225, providing a balance between a sharp cutting edge and edge stability for variable conditions. The PVD-coated layer increases wear resistance and reduces built-up edge, which is particularly important when machining stainless steel, where workhardening and adhesion commonly shorten tool life. This configuration supports higher cutting speeds and more consistent part quality, resulting in improved cycle times and lower cost per component over medium production runs.

Precision geometry for consistent surface finish and repeatability

Designed with a 60° included angle and a 0.4 mm corner radius, the geometry of the insert delivers predictable cutting forces and a consistent surface finish on turned components. The triangular 16 mm format permits indexable use on both sides, while the thickness of 4.76 mm contributes to rigidity and vibration damping in marginally stable set-ups. The insert’s 0° clearance angle and ISO-compliant form mean compatibility depends on matching the holder’s form, tolerance class, fastening and size; when matched correctly, the result is reproducible positioning and repeatable machining results across batches.

Simple integration and economical machining for the workshop

As a double-sided indexable insert with a cylindrical hole, the component is straightforward to clamp in standard ISO holders and boring bars; the system typically comprises the insert, a matched external holder or boring bar, a support/locking set and replacement screws. The double-sided chipbreaker reduces downtime, since the insert can be rotated to a fresh edge, and the PVD-coated surface helps maintain edge integrity across interrupted and continuous cuts. The outcome is enhanced productivity and predictable tool-change intervals, supporting leaner tool inventories and steadier production flow.

FAQ

What materials is this insert best suited for?
The TNMG160404 AH6225 insert is formulated primarily for machining stainless steel, providing a good balance of edge sharpness and wear resistance for medium turning operations.

Is the insert reversible and how many cutting edges are available?
The insert is double-sided and triangular, offering multiple usable cutting edges to extend tool life before replacement.

What does the 0.4 mm corner radius mean for component finish?
A 0.4 mm radius helps achieve a compromise between edge strength and surface finish; smaller radii generate finer finishes, while this radius adds robustness for stability in medium cuts.

Which holders are compatible with this ISO insert?
Compatibility requires a holder matching the insert form, clearance angle, tolerance class, fastening method, size and thickness; when these parameters align, standard ISO external holders or boring bars are suitable.
