TNMG 160404 AH6235 Turning Insert — PVD-coated carbide, 0.4 mm radius (Tungaloy)

The TNMG160404 AH6235 is an ISO-standard triangular turning insert for external and internal turning, optimised for operations with rostfreier Stahl and challenging interrupted cuts.

• ISO TNMG160404 triangular insert
• PVD-coated carbide AH6235 grade
• Designed for rostfreier Stahl and interrupted cuts
• Double-sided chipbreaker and cylindrical hole

Robust cutting performance on rostfreier Stahl

The PVD-coated carbide grade AH6235 combines toughness with a coating that improves resistance to notch wear and chipping in demanding applications. For machining rostfreier Stahl, this composition is chosen to tolerate workpiece adhesion and intermittent engagement; the coating provides thermal stability while the substrate resists mechanical breakouts. The insert’s 0.4 mm radius and 60° geometry balance strength at the cutting edge with the ability to produce acceptable surface finish, making the tool suited to both heavy interruptions and smooth feed runs without frequent edge changes.

Simple integration into ISO tooling systems

As an ISO-standard insert, the plate integrates with compatible triangular holders when form, relief angle, tolerance class, fastening, size and thickness match. The plate is triangular with a cylindrical hole, enabling positive location and secure clamping, while the double-sided chipbreaker allows turning the plate for a second cutting edge, improving economy per index. These design elements reduce changeover time and simplify inventory management in a workshop environment, because replacement follows standardised mounting and orientation rather than bespoke tooling.

Practical benefits for productivity and process stability

The combination of a PVD coating and a double-sided chipbreaker targets reduced edge wear and controlled chip formation, which contributes to longer tool life and fewer unplanned interruptions. For shop-floor planning, this means steadier cycle times and less rework on turned components. The plate’s dimensions and hole style support stable clamping; when matched with a suitable external holder or boring bar, the system yields repeatable results for both external turning and internal operations, preserving surface quality while mitigating the risk of edge chipping during unstable cuts.
