VBMT 110304 AH6235 Wendeplatten - Tungaloy

Reliable machining of stainless-grade materials and secure performance in interrupted cuts result from the combination of the PVD-coated AH6235 carbide grade, the PS chipbreaker, and the precise VBMT110304-PS geometry; order directly via Metav Werkzeuge or consult our specialists for application advice.

VBMT110304-PS AH6235 — ISO turning insert for external and internal turning (rhombic, 35°) by Tungaloy

The VBMT110304-PS AH6235 is an ISO rhombic turning insert engineered for robust external and internal turning, especially suited to stainless steels and interrupted cutting conditions.

• PVD-coated carbide AH6235
• 0.4 mm corner radius
• 35° rhombic geometry
• PS chipbreaker for unstable cuts

Consistent performance in stainless steel turning

The insert’s PVD-coated carbide grade AH6235 delivers a tougher cutting edge designed to resist chipping during starts, stops and interrupted cuts. This results in fewer unplanned tool changes and more consistent cycle times when machining rostfreiem Stahl, where adhesion and work-hardening can otherwise reduce process stability. The PS chipbreaker promotes manageable chip formation under variable cutting conditions; selecting this chip control feature helps to maintain surface finish while reducing the risk of edge failure.

Secure mounting and wide holder compatibility

Compatibility is ensured by standardised ISO geometry: insert form, relief angle, tolerance class, mounting, size and thickness determine fit. The insert has a cylindrical hole with single-sided countersink (40°–60°) for secure clamping and repeatable seating in suitably rated external holders or boring bars. Specifying the correct holder and clamping set for the rhombic 35° geometry and 5° relief angle optimises stability and reduces vibration, which directly improves tool life and surface integrity.

Geometry and dimensions that balance finishing and robustness

A 0.4 mm corner radius and a 3.18 mm plate thickness balance cutting edge strength with the ability to produce fine surfaces. The rhombic shape and the shallow principal cutting angle favour finishing passes while still tolerating moderate depths of cut in shop-floor turning. For roughing or higher material removal rates, pairing the plate with a heavy-duty holder and adapting feed rates ensures the geometry’s benefits are fully realised without overstressing the cutting edge.

Material and coating advantages for extended productivity

The combination of PVD coating and the AH6235 substrate enhances resistance to built-up edge and thermal softening, which are frequent challenges when turning stainless steels. This composition supports longer tool life and predictable performance across repeated batches, reducing downtime. For workshops seeking a standardised solution, the ISO-series insert integrates into common tool systems, simplifying inventory management and enabling quick replacement with the VBMT110304-PS geometry.

FAQ

What materials is this insert best suited to machine?
The VBMT110304-PS AH6235 insert is formulated for machining rostfreiem Stahl (stainless steel) and performs well in interrupted cutting, thanks to the tougher AH6235 grade and its PVD coating.

How does the PS chipbreaker affect cutting behaviour?
The PS chipbreaker controls chip form in unstable or interrupted cuts; with the VBMT110304-PS AH6235 it helps reduce edge chipping and supports safer chip evacuation during turning.

Which holder compatibility factors need checking before purchase?
Verify holder compatibility for the ISO VBMT form by checking form fit, relief angle (5°), tolerance class, mounting method, insert size (11 mm) and thickness (3.18 mm) to ensure secure clamping.

Can this insert be used for finishing as well as roughing?
Yes; the 0.4 mm corner radius and rhombic 35° geometry provide a balance that allows quality finishing passes while still tolerating moderate roughing when matched with suitable feeds and a rigid setup.

Is the VBMT110304-PS AH6235 available as single-sided and indexed?
The VBMT110304-PS AH6235 is an ISO rhombic insert designed for indexing and repeatable seating; check the specific holder and clamping set to confirm indexing capability in the chosen system.
