TNMG160404 AH6225 Tungaloy turning insert — PVD‑coated carbide, 60° triangle

The TNMG160404 AH6225 is an ISO‑standard triangular turning insert engineered for universal use in medium‑range machining of rostfreier Stahl.

• PVD-coated carbide for long tool life
• Universal grade for rostfreier Stahl
• 60° triangle, 0.4 mm corner radius
• Cylindrical hole with double-sided chipbreaker

Reliable cutting performance for rostfreier Stahl

The TNMG160404 insert is delivered in AH6225, a PVD‑coated carbide grade designed as a universal solution for rostfreier Stahl. The combination of a sharp yet stable cutting edge and a wear‑resistant coating reduces flank wear and maintains dimensional accuracy across interrupted cuts and variable cutting conditions. For production environments where tool changes influence throughput, this balance of edge strength and abrasion resistance supports consistent component quality and longer tool intervals, helping to lower process costs while preserving surface finish.

Geometry engineered for secure clamping and chip control

A triangular plate with a 60° included angle and a 0.4 mm corner radius provides a predictable contact geometry that is compatible with a wide range of external holders. The cylindrical hole and standard ISO form permit reliable clamping; compatibility depends on holder form, rake angle, tolerance class, fastening, size and thickness. The integrated double‑sided chipbreaker promotes controlled chip formation during turning, which reduces the risk of entanglement and supports efficient swarf evacuation. For less experienced users, a brief explanation: a chipbreaker reshapes the chip so it fractures or curls away, protecting the workpiece and reducing spindle load.

Designed for efficient production and consistent results

Built to ISO dimensions, this cutting insert is intended to contribute to stable production cycles and reproducible outcomes. The PVD coating improves resistance to adhesion and thermal degradation, which is particularly relevant when machining rostfreier Stahl at moderate cutting speeds. The insert’s balanced properties support predictable tool life and reduce unexpected stoppages; in process terms, this translates into higher overall equipment effectiveness. Where economic arguments are required, the use of a universal grade often reduces the need for multiple specialised grades, simplifying inventory management.

Practical system guidance for selection and setup

The insert functions as part of a system: an ISO turning insert, a matching external holder or boring bar, a shim/clamp set and replacement screws form the complete assembly. Selection of the correct chipbreaker and grade should be based on workpiece material, machining type and setup rigidity. For unstable setups, a more robust grade or reduced cutting parameter is advisable; for stable, high‑precision turning the combination of small corner radius and sharp geometry supports fine surface finishes. When compatibility questions arise, check holder geometry against the insert’s form and thickness; the tolerance class and fastening method determine seating accuracy.
