VNMG 120404 AH6235 — ISO turning insert, PVD-coated carbide, Tungaloy

A VNMG120404E-SS AH6235 rhombic ISO insert for external and internal turning, engineered for rostfreier Stahl and interrupted‑cut applications

• ISO turning insert VNMG120404E-SS
• PVD-coated carbide grade AH6235
• Optimised SS chipbreaker for interrupted cuts
• 35° lead angle, 0.4 mm corner radius

Reliable cutting performance for demanding rostfreier Stahl operations

The PVD‑coated AH6235 grade brings enhanced toughness and wear resistance where chips and built‑up edge are critical. Designed for machining rostfreier Stahl, the insert offers a balance between edge stability and fracture resistance, which reduces unplanned tool changes and increases productive cutting time. The PVD-coated surface improves adhesion resistance and contributes to more consistent cutting forces, resulting in fewer rejects and steadier cycle times for series production.

Geometry and chip control that improve process stability

The rhombic form with a 35° lead angle and 0° relief produces a cutting geometry that supports a secure seating in ISO holders and a predictable cutting direction, improving surface finish and dimensional control. The SS chipbreaker is optimised for interrupted cuts and sticky materials; it promotes repeatable chip formation and evacuation, lowering the risk of jamming. A 0.4 mm corner radius provides a compromise between strength and finish, reducing the likelihood of edge chipping in less stable setups.

Practical integration and economic advantages

Compatibility with ISO holders is dictated by form, clearance, tolerance class, fixing method, size and thickness; the ISO designation VNMG120404E-SS simplifies procurement and tool selection. Using this insert reduces downtime through fewer breakages and longer edge life, which improves overall tool cost per part. For shops processing mixed batches or facing frequent interruptions, the combination of the AH6235 grade and the SS chipbreaker delivers both reliability and predictable maintenance intervals.

Guidance for application and safe use

Select the cutting parameters and insert seating that match the workpiece stability and machining strategy: lower feeds and conservative depths are recommended when first testing this configuration in new rostfreier Stahl alloys. The insert is suitable for both external and internal turning; pairing with an appropriate outer holder, clamping kit and replacement screws as per ISO standards ensures correct seating and repeatable results. For parameter recommendations and trial setups, operational teams and engineers can request tailored data.

FAQ

What materials is this insert best suited for?
The VNMG120404E-SS AH6235 is optimised for rostfreier Stahl and performs well in interrupted‑cut conditions, thanks to its PVD‑coated AH6235 grade and SS chipbreaker.

Is this insert compatible with standard ISO holders?
Yes; the VNMG120404E-SS follows ISO geometry, but compatibility depends on holder form, clearance, tolerance class, fixing and plate thickness—ensure the holder matches these parameters.

Which features reduce chipping risk during interrupted cuts?
The combination of a tougher AH6235 grade, the SS chipbreaker and a 0.4 mm corner radius helps prevent edge fracture and improves durability in interrupted‑cut applications.

Can this insert be used for finishing passes?
With its 35° lead angle and 0.4 mm radius, the insert can produce good surface quality; select conservative feeds and adjust cutting conditions for fine finishing runs.
