TNMG160402 AH6225 TNMG indexable turning insert — PVD-coated carbide, 60°

The TNMG160402 AH6225 is an ISO-format triangular indexable insert designed for external and internal turning, optimised for medium machining of stainless steels and variable working conditions

• PVD-coated carbide for robust cutting
• Universal grade for stainless steels
• Double-sided chipbreaker for consistent chips
• ISO triangular 16 mm configuration

Reliable cutting performance for stainless steels

The AH6225 grade is a PVD-coated carbide developed as a universal solution for stainless steels, offering a balance between edge sharpness and wear resistance. The coating supports thermal stability and reduces adhesion during intermittent cuts, while the substrate provides mechanical strength for stable machining. As a result, the insert delivers consistent surface quality and predictable flank wear in medium-duty turning applications, reducing process variation and downtime.

Consistent chip formation and process stability

Equipped with a double-sided chipbreaker, the insert promotes reliable chip control across a range of cutting parameters. The chipbreaker geometry reduces long, stringy chips and helps avoid chip entanglement in both external and internal turning. This leads to improved cycle times and safer machining conditions, particularly when turning slender components or interrupted cuts. The combination of chip management and grade selection contributes directly to higher process stability and lower scrap rates.

Straightforward integration into ISO tool systems

The insert follows ISO conventions, which simplifies tooling logistics: the triangular 16 mm format and standard attachment features ensure compatibility with a wide range of holders and boring bars. Key dimensions — 4.76 mm thickness, 0.2 mm corner radius and a cylindrical hole for secure clamping — allow predictable seating and repeatable indexing. The 0° clearance angle and the 60° included angle of the triangle align with common holder geometries, making changeover and replacement straightforward in mixed-tool environments.

Practical benefits for production and maintenance

Using a universal grade like AH6225 reduces the number of different inserts required in the tool crib, simplifying inventory while covering a broad spectrum of stainless steel alloys. The PVD coating improves resistance to built-up edge and thermal softening, which means less frequent tool changes and lower running costs per component. When paired with an appropriate holder and cutting data adapted to material and rigidity, the insert supports steady productivity and reliable surface finish without demanding excessive operator adjustment.

FAQ

What materials is this insert optimised for?
The TNMG160402 AH6225 insert is optimised for machining stainless steels, offering a compromise between edge sharpness and wear resistance for medium turning tasks.

How does the double-sided chipbreaker benefit the machining process?
The double-sided chipbreaker on this indexable insert promotes controlled chip formation and reduces chip stringing, enhancing process stability during both external and internal turning.

Which holders are compatible with the TNMG160402 format?
Compatibility is determined by the ISO triangular form, clearance angle and thickness; this ISO-format insert fits standard TNMG-compatible external holders and boring bars when matched by size and clamping design.

What are the key dimensions to consider when replacing an insert?
Relevant dimensions include 16 mm side size, 4.76 mm thickness, 0.2 mm corner radius and the presence of a cylindrical hole for secure clamping.

Is the coating suitable for interrupted cuts and variable conditions?
Yes, the PVD coating combined with the AH6225 substrate provides good thermal and mechanical resistance, making the insert suitable for interrupted cuts and changing operational conditions.
