TNMG 160408 AH6225 Wendeplatten - Tungaloy

Benefit from a combination of high cutting stability and broad material coverage: the PVD-coated carbide delivers consistent edge quality while the AH6225 grade is optimised for stainless-steel turning, and the triangular 60° geometry with a 0.8 mm corner radius ensures reliable mid-range performance; order the TNMG160408 AH6225 Tungaloy insert directly via Metav Werkzeuge or ask our consultants if needed.

TNMG 160408 AH6225 turning insert – Tungaloy (triangular, PVD-coated carbide, 60°)

The TNMG160408 AH6225 is an ISO-standard triangular turning insert designed for versatile external and internal turning in mixed and stainless-steel applications

• PVD-coated carbide for stable cutting edges
• Universal AH6225 grade for stainless steel
• Triangular 60° form for versatile turning
• Double-sided chipbreaker, cylindrical hole

Precise cutting performance for efficient production

The insert combines a PVD coating with a wear-resistant carbide substrate to maintain a sharp, stable cutting edge across variable conditions. This results in predictable tool life and consistent part finish, reducing rework and machine downtime. The AH6225 formulation is aimed at applications where stainless-steel machining demands compromise between edge toughness and wear resistance, enabling higher feeds and reliable chip control without sacrificing surface quality.

Compatibility and system integration to simplify setup

Designed as an ISO-norm insert, the geometry and hole style ensure straightforward fitment in standard external holders and boring bars. The 60° triangle shape allows indexable reuse of cutting corners, while the cylindrical hole ensures positive clamping. This compatibility reduces inventory complexity and supports fast insert changes, which in turn shortens non-productive time during batch work or tool changeovers.

Process reliability and edge life under varying conditions

A double-sided chipbreaker and the balanced corner radius of 0.8 mm deliver stable chip formation in interrupted cuts and variable workpiece rigidity. The combination of edge geometry and coating lowers the risk of built-up edge and flank wear when machining mixed batches, improving first-pass quality. Selecting the correct grade and chipbreaker for the workpiece material gives a measurable improvement in cycle time and cost per component.

Practical guidance for application and handling

For general turning tasks select the AH6225 insert when stainless-steel components are predominant or when mixed materials require a reliable, universal solution. Use appropriate feeds and moderate speeds initially, then optimise cutting parameters based on observed chip form and surface finish. Replace or re-index the insert when edge rounding or notch wear becomes visible to preserve dimensional accuracy and to avoid excessive forces on the holder.

FAQ

What materials is this insert best suited for?
The AH6225 grade is designed as a universal grade for stainless steel and performs well in a range of mixed steels during turning operations.

Can the insert be used on internal and external turning tasks?
Yes, the triangular TNMG160408 geometry and standard hole style make the insert suitable for both external and internal turning with compatible holders.

How does the chipbreaker affect machining performance?
The double-sided chipbreaker promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of chip entanglement during interrupted cuts.

What is the benefit of the 0.8 mm corner radius?
A 0.8 mm corner radius balances edge strength and finish: it provides increased durability in medium-duty cuts while maintaining acceptable surface quality.

Is this insert indexable and reversible?
The triangular, double-sided design allows multiple index positions to be used, extending the number of available cutting edges per insert and improving cost efficiency.
