WNMG 080408 AH6235 Wendeplatten - Tungaloy

Compact reliability and material-specific performance combine in this insert: PVD-coated AH6235 carbide and a 0.8 mm corner radius deliver improved resistance to chipping in stainless steel and interrupted cuts, while the ISO WNMG geometry ensures straightforward replacement in standard holders; order or request advice via Metav Werkzeuge for immediate integration into production.

WNMG 080408 AH6235 – ISO turning insert (0.8 mm radius, PVD) by Tungaloy

A WNMG 080408 AH6235 insert designed for ISO-compliant external and internal turning, optimised for stainless steels and interrupted cutting where edge security and reliable chip control are required

• PVD-coated carbide grade AH6235
• 0.8 mm corner radius
• 0° relief for stable cutting
• Trigon form, 80° included angle

Consistent performance for stainless and interrupted turning

The PVD-coated, toughened carbide of grade AH6235 provides a balance between wear resistance and fracture toughness that is particularly suited to stainless steel and operations with frequent interruptions. The protective coating reduces built-up edge and increases heat resistance, meaning machining parameters can be pushed for higher metal removal rates without compromising insert life. This results in fewer tool changes and steadier part quality in serial production.

Improved chip control and protected cutting edge

The SA chipbreaker, combined with the trigon shape and an 80° included angle, channels chips reliably and reduces vibration during cut engagement. The 0.8 mm corner radius contributes to edge strength on approach and exit, while the 0° relief ensures predictable contact geometry with the workpiece. Together these features lower the risk of edge breakout in unstable cuts and support consistent surface finish on prismatic components.

Straightforward integration with ISO holder systems

As an ISO-format indexable insert, the WNMG080408-SA designation guarantees compatibility with standard external holders and boring bars when form, clearance angle, tolerance class, fastening, size and thickness are matched. The plate thickness of 4.76 mm and the trigon contour simplify selection of a suitable clamping set and replacement screws; holders designed for WNMG plates will accept the insert for both internal and external turning operations, enabling rapid changeover and reduced setup time.

Productivity gains and predictable service life

Selecting a tougher, PVD-coated grade like AH6235 reduces unplanned downtime through improved edge security and extended cutting intervals. The combination of robust material, chip control and ISO conformity supports stable, repeatable processes—benefits that translate to lower unit costs over medium to large production runs. For manufacturers aiming at a balance of performance and economy, these inserts offer a measurable contribution to throughput and process reliability.

FAQ

What materials is this insert best suited to? The WNMG 080408 AH6235 insert is formulated for stainless steel and mixed applications where interrupted cuts occur; its PVD-coated carbide composition improves resistance to edge breakage in tougher alloys.

Which geometry details should be noted for setup? The insert has a trigon form with an 80° included angle, a corner radius of 0.8 mm, a plate thickness of 4.76 mm and a cylindrical hole for fixing; these dimensions determine compatible holder selection.

How does the SA chipbreaker influence performance? The SA chipbreaker stabilises chip flow and reduces cutting forces in many turning tasks, which helps protect the cutting edge and supports consistent surface finish in serial machining.

Is the WNMG080408-SA compatible with standard ISO holders? Yes, the ISO WNMG designation means the insert fits ISO-compliant external holders and boring bars when form, relief, tolerance class, fastening, size and thickness are matched.

What are the main benefits of the AH6235 grade? The AH6235 grade offers a tougher substrate with a PVD coating that improves thermal stability and reduces built-up edge, resulting in more predictable tool life and fewer interruptions for insert changes.
