VNMG 160412 AH6235 indexable turning insert — ISO VNMG, 35° rhombic by Tungaloy

VNMG160412 AH6235 Tungaloy indexable insert for turning applications, PVD-coated carbide grade optimised for stainless steels and interrupted cuts

• PVD-coated carbide grade AH6235
• For stainless steels and interrupted cuts
• Rhombic VNMG with 35° approach angle
• Double-sided chipbreaker, cylindrical hole

Consistent cutting performance with a tougher PVD-coated grade

The insert is made from a PVD-coated carbide designed as grade AH6235, providing a balance of toughness and wear resistance that is particularly suited to stainless steels and operations with frequent interruptions. The coating improves surface endurance under abrasive conditions, while the substrate’s toughness mitigates chipping in unstable cuts. This combination reduces scrap rates and supports longer uninterrupted machining cycles, which makes it a pragmatic choice where tool life and process reliability are priorities.

Geometry and dimensions engineered for stable turning

With a 35° rhombic geometry and a corner radius of 1.2 mm, the insert offers a controlled engagement in the cut that favours dimensional stability and surface finish. The insert thickness of 4.76 mm and the standard ISO VNMG160412 form ensure mechanical rigidity when paired with a suitable external holder or boring bar. The 0° relief angle and the central cylindrical hole enable secure clamping and repeatable siting in the tool pocket, reducing setup variation and maintaining consistent cutting conditions.

Designed to handle interrupted cuts and breakout-prone materials

The double-sided chipbreaker pattern and the tougher carbide composition make this insert advantageous for interrupted cutting and for workpieces with variable feed or hard inclusions. The chipbreaker geometry helps control chip flow and reduces the risk of built-up edge, improving both tool life and surface quality. For operations where breakouts are a concern, choosing this insert grade provides a practical reduction in downtime due to fewer insert changes and less unexpected tool failure.

System compatibility and economical machining

As an ISO-standard turning insert, compatibility with holders is governed by shape, relief angle, tolerance class, clamping method, size and thickness; typical system components include an external holder or boring bar, a locating shim and clamping screws. The insert’s double-sided form allows rotation to a fresh cutting edge, effectively doubling usable life per insert and improving cost-efficiency in batch production. Selecting appropriate holder rigidity and cutting parameters will convert the material and geometry benefits into measurable productivity gains.

FAQ

What materials is this insert best suited for?
The VNMG160412 AH6235 insert is optimised for stainless steels and other materials that benefit from a tougher PVD-coated carbide grade, with specific advantage in interrupted cuts.

Can the insert be rotated or indexed to extend life?
Yes. The double-sided VNMG form allows indexing to a fresh cutting edge, effectively extending service life before replacement is required.

Is the VNMG160412 compatible with standard ISO holders?
Compatibility depends on holder form, relief angle and clamping method; the insert follows ISO VNMG dimensions and fits holders designed for VNMG160412 geometry.

How does the chipbreaker affect machining?
The double-sided chipbreaker controls chip formation and evacuation, reducing built-up edge and improving surface finish in unstable cutting conditions.

Which grade and coating does this insert use and what does that mean?
The insert uses grade AH6235, a PVD-coated carbide offering increased toughness for breakout-prone and interrupted turning tasks, promoting longer life in such applications.
