TNMG 160404 AH6225 — Tungaloy indexable turning insert for ISO turning

The TNMG 160404 AH6225 is an ISO-spec triangular indexable insert designed for general-purpose external and internal turning; optimised for stainless steel and variable cutting conditions.

• PVD-coated universal grade AH6225
• Optimised for stainless steel machining
• 60° triangular form TNMG geometry
• 0.4 mm corner radius for improved finish
• Double-sided chipbreaker, cylindrical hole fixing

High-performance turning where stability matters

The combination of a PVD-coated surface and carbide substrate delivers a balance between wear resistance and a keen cutting edge suited to medium-duty operations. The AH6225 grade is formulated as a universal option for machining stainless steel, offering reliable edge stability under changing cutting conditions. The coated surface reduces built-up edge and improves thermal resistance, which translates into more consistent tool life and predictable process windows. For production environments that prioritise throughput and repeatability, this insert supports steady cycle times and reduced scrap rates.

Practical benefits on the toolholder and workpiece

The TNMG triangular geometry with a 60° included angle offers versatile engagement on common external and internal turning toolholders. The 0.4 mm corner radius contributes to a fine surface finish while maintaining sufficient edge strength for medium roughing and finishing passes. The insert is double-sided and features a cylindrical hole for secure clamping, enabling rapid re-indexing and economical use of cutting edges. This reduces tooling costs per machined part and simplifies inventory management, as a single ISO insert form can cover multiple turning tasks when combined with the appropriate chipbreaker and grade.

Choosing and matching the insert for reliable results

Compatibility to a chosen holder is governed by factors such as insert form, clearance angle (0°), tolerance class, fastening method, size and thickness, all of which align with ISO standards. Select the double-sided chipbreaker variant and match the AH6225 grade to the workpiece and machine rigidity to achieve optimal chip control and surface quality. The ISO designation and standardised dimensions make it straightforward to replace worn inserts without extensive setup changes. Where stability is limited, favour conservative cutting parameters and the chipbreaker that best suits the material and depth of cut.

FAQ

What machining tasks is this insert suited for?
The TNMG 160404 AH6225 insert is intended for external and internal turning operations, offering a universal solution especially for stainless steel where a stable, sharp edge is required.

How does the AH6225 grade perform on stainless steel?
AH6225 provides a PVD-enhanced wear resistance that helps control built-up edge and maintain a strong cutting edge during medium-duty machining of stainless steel, giving repeatable surface quality.

Can the insert be re-indexed to use multiple edges?
Yes, the double-sided TNMG design and the cylindrical hole for secure fixing permit re-indexing to access additional cutting edges, improving cost efficiency per edge.

Which holders are compatible with this TNMG insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; matching ISO TNMG specifications ensures a proper fit and secure clamping.

Why choose a PVD coating for this application?
A PVD-coated surface enhances thermal and abrasive resistance, reducing adhesion and wear when machining challenging materials such as stainless steel, which supports longer tool life and steadier performance.
