TNMG 160404 AH6235 Wendeplatten - Tungaloy

High process security and extended tool life come from the combination of the AH6235 PVD-coated carbide grade, the double-sided chipbreaker, and the repeatable ISO triangular geometry with a 0.4 mm corner radius; order the insert directly via Metav Werkzeuge or consult our technical team for holder compatibility.

TNMG 160404 AH6235 — Indexable turning insert (Turning) — Tungaloy

The TNMG160404 AH6235 is an ISO indexable turning insert engineered for external and internal turning, especially suited to stainless steel and interrupted cutting conditions

• TNMG 160404 geometry, ISO triangle insert
• AH6235 PVD-coated carbide grade
• Double-sided chipbreaker for stable chips
• 0.4 mm corner radius, 60° cutting angle

Reliable cutting in stainless and challenging materials

The combination of a PVD-coated carbide substrate and the AH6235 grade delivers a balance of toughness and wear resistance that is particularly effective on stainless steel and in operations with interrupted cuts. The tougher matrix reduces the likelihood of edge chipping and spontaneous breakout, which means fewer unplanned insert changes and more stable production cycles. Because the grade is optimised for resilience rather than maximum hardness, the result is improved tool life under variable cutting forces and higher confidence when machining difficult-to-cut alloys.

Accurate geometry for predictable part quality

The ISO triangular format with a 60° cutting angle and a 0.4 mm corner radius provides a predictable cutting profile and easy integration into standard turning holders. The neutral 0° relief angle suits neutral cutting geometries and helps maintain consistent contact conditions between insert and workpiece. Compatibility with a given holder is determined by insert form, clearance angle, tolerance class, fixing method, size and thickness, so the standard ISO designation simplifies selection and replacement. This geometry supports repeatable dimensional control, reducing downstream finishing and inspection efforts.

Chip control and process stability for productive machining

The double-sided chipbreaker is designed to generate short, controllable chips under a range of feeds and depths of cut; this improves swarf evacuation and reduces downtime caused by chip entanglement. In combination with the PVD surface finish, the insert lowers cutting forces and helps maintain surface integrity, which can shorten cycle times and reduce rework. For external and internal turning, matching chipbreaker and grade to workpiece, machining method and machine-tool rigidity is recommended to maximise throughput and surface quality. If further machining parameters are required, our team can provide guidance to tune feed, speed and depth for the best balance of performance and economy.

FAQ

What workpieces is this insert best suited for?
The TNMG160404 AH6235 insert is formulated for stainless steel and other tough alloys, and it performs well in interrupted cuts and operations with higher breakout risk.

How does the AH6235 grade affect tool life?
The AH6235 PVD-coated carbide grade emphasises toughness and stable edge behaviour, which reduces chipping and typically extends tool life in demanding turning tasks.

Can the insert be used on both external and internal turning operations?
Yes, the triangular ISO geometry and the double-sided chipbreaker make the insert suitable for both external and internal turning when the correct holder and cutting parameters are selected.

What does the 0.4 mm corner radius change in the final part?
A 0.4 mm corner radius improves edge strength and can produce stronger corner profiles, reducing the risk of corner chipping while slightly influencing the surface finish and tool forces.

Is the TNMG160404 compatible with standard ISO turning holders?
The ISO designation facilitates compatibility, but final fitting depends on holder form, fixing method, tolerance class and insert thickness; confirm these dimensions against the holder specification.
