TNMG 160408 AH6225 TNMG – ISO turning insert for turning, Tungaloy

TNMG 160408 AH6225 TNMG is an ISO‑standard turning insert designed for external and internal turning; the triangular form and 60° included angle suit a wide range of operations

• TNMG geometry with 60° triangle
• PVD-coated carbide grade AH6225
• Double-sided chipbreaker for varied cuts
• ISO compatibility, with cylindrical hole

Consistent cutting performance with a universal grade

The combination of a PVD-coated carbide substrate and the AH6225 grade provides a balance between edge sharpness and wear resistance tailored to stainless steels. The coating reduces adhesion and improves thermal stability, which extends tool life under varying conditions. As a result, productivity gains are achieved through fewer indexings and predictable edge wear. The triangular ISO insert geometry contributes to stability during heavier cuts while allowing efficient finishing passes.

Geometry and chip control that simplify process planning

The insert’s 60° included angle and 0.8 mm corner radius create a robust cutting edge that tolerates interrupted cuts and reduces chipping risk. The double-sided chipbreaker supports consistent chip control across a range of feeds and depths, lowering the risk of long, stringy chips that hamper cycle times. For production planning, these features translate into fewer tool changes and improved cycle consistency, supporting predictable throughput and cost efficiency.

Compatibility and handling for workshop efficiency

As an ISO‑compliant part, the insert fits standard holders when form, free angle, tolerance class, fastening, size and thickness match the toolholder specification. The cylindrical hole allows secure clamping and quick indexing, simplifying inventory handling and reducing setup time. The insert’s thickness and nominal size provide mechanical stiffness for stable turning; this reliability supports repeatable surface finishes and dimensional accuracy on batch work.

Practical benefits and application guidance

Designed for turning operations, the grade suits medium machining of stainless steels under changing conditions; the material and coating combination promotes stable chip formation and reliable edge behaviour. For finishing or light machining where a finer surface is required, the geometry and chipformer support smooth results. Selection of the matching holder and correct clearance must follow ISO specifications to ensure optimal performance and tool life.
