VNMG160408-TF AH6225 ISO 160408 turning insert — PVD-coated carbide, 0.8 mm radius (Tungaloy)

The VNMG160408-TF AH6225 is an ISO rhombic turning insert engineered for external and internal turning, offering a sharp yet stable cutting edge for machining stainless steels under changing conditions.

• PVD-coated carbide grade AH6225
• Optimised for stainless steels
• 0.8 mm corner radius for stable cutting
• ISO rhombic VNMG 35° geometry

Consistent performance on stainless steels

The insert’s PVD-coated carbide matrix (grade AH6225) is formulated to handle the work-hardening tendency of many stainless steels. A thin PVD layer reduces adhesion of workpiece material to the tool while maintaining thermal strength at the cutting edge, which translates into fewer built-up-edge problems and more consistent surface finishes. For applications that demand repeatable, medium-duty turning, this combination reduces process variation and improves component quality without complex parameter changes.

Geometry that stabilises cutting and chip control

The rhombic 35° geometry and 0.8 mm corner radius provide a balance between cutting edge strength and form fidelity. The TF chipbreaker promotes controlled chip formation, reducing the risk of long, tangled chips in unattended operations and improving swarf evacuation in both external and internal turning. The 0° relief angle supports a defined cutting action, which helps maintain dimensional accuracy and prolongs the interval between indexings or insert changes.

ISO compatibility for straightforward system integration

As an ISO-standard VNMG insert (ISO code 160408), mechanical compatibility with appropriate external holders is determined by form, relief angle, tolerance class, fastening and thickness. The insert is supplied with a cylindrical locating hole to suit clamping systems that use a central screw and pad. A properly matched holder, shim and clamp ensure repeatable seating and torque distribution, so the tool system performs reliably across batches and tool changes.

Shop-floor advantages and application guidance

Designed for turning tasks where mid-range cutting parameters and variable conditions are expected, the insert supports stable production runs with minimal setup adjustments. The robust cutting edge reduces the need for frequent tool intervention in serial production, while the PVD surface lowers friction and improves surface finish. Where finish and dimensional control are priorities, selecting this insert with a holder tuned for stiffness yields measurable gains in productivity and part quality.

FAQ

Which materials is this insert best suited for?
The VNMG160408-TF AH6225 is optimised for machining stainless steels; the PVD-coated carbide grade AH6225 helps resist adhesion and sustain edge stability during medium machining.

Can this insert be used for both external and internal turning?
Yes. The rhombic VNMG geometry and TF chipbreaker make the insert suitable for both external and internal turning operations when paired with an appropriate holder.

What significance has the TF chipbreaker?
The TF chipbreaker on this insert promotes short, controllable chips, improving swarf management and reducing the likelihood of chip-related interruptions during turning.

What are the key dimensions and angles to check when selecting a holder?
Verify the ISO code (160408), insert size (16), corner radius (0.8 mm), relief angle (0°) and the central cylindrical hole to ensure proper seating and clamping in the chosen holder.

How does the AH6225 grade affect tool life and finish?
The AH6225 PVD-coated grade is balanced for a sharp but stable cutting edge; it helps deliver consistent surface finish and predictable edge wear under variable cutting conditions.
