VBMT 160404 AH6235 — ISO turning insert (PS chipbreaker) by Tungaloy

VBMT160404-PS AH6235 is an ISO-format indexable turning insert designed for external and internal turning, optimised for stainless steels and interrupted cuts.

• PVD-coated carbide grade AH6235
• Optimised for stainless steel and interrupted cuts
• Rhombic ISO shape VBMT 160404
• Cylindrical hole with single-sided countersink (40°–60°)

Maximum process reliability for stainless-steel turning

The insert offers consistent performance in demanding turning tasks thanks to the PVD-coated carbide grade AH6235, developed for tougher materials and interrupted cuts. The combination of the PS chipbreaker and the insert geometry reduces the risk of edge chipping and supports stable cutting even when machining work-hardened or adhesive-prone surfaces. For production contexts where repeatability and minimised rework are priorities, this geometry lowers scrap rates and secures machining windows.

Predictable chip control and extended tool life

With a 0.4 mm corner radius and a 5° clearance angle, the insert balances edge strength and cutting forces to deliver improved surface finish and resistance to mechanical shock. The PS chipbreaker assists in forming short, controllable chips on stainless steel grades, which simplifies swarf handling and reduces downtime for cleaning. In practice, this means fewer unexpected stoppages and more predictable tool-change intervals, supporting higher machine utilisation and better overall economy per cutting hour.

Simple integration into ISO tool systems and flexible application

The insert conforms to ISO sizing and fits common external holders and boring bars when matched for form, clearance, tolerance class, fastening and thickness. The cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and repeatable positioning in standard seating systems. As part of a system consisting of an ISO insert, a compatible holder, and suitable clamps and screws, the component provides straightforward replacement and stock management, especially valuable for workshops aiming to standardise tooling across multiple machines.

FAQ

What materials is this insert best suited for?
The VBMT160404-PS AH6235 insert is formulated for stainless steel and other adhesive or tough materials; the AH6235 grade and PS chipbreaker improve performance in interrupted cuts and challenging surfaces.

How does the PS chipbreaker affect chip formation?
The PS chipbreaker promotes short, controlled chips on ductile materials, reducing swarf entanglement and facilitating safer, cleaner machining with the AH6235 PVD-coated carbide insert.

Will this insert fit my existing ISO holders?
Compatibility depends on holder form, clearance angles, tolerance class, fastening and thickness; the ISO format and the cylindrical hole with countersink are designed for standard ISO clamping systems.

What benefits does the 0.4 mm corner radius provide?
A 0.4 mm corner radius increases edge strength compared with finer radii, offering better resistance to edge chipping during interrupted cuts while still enabling good surface finish when properly applied.

How should the insert be specified when ordering?
Order using the designation VBMT160404-PS AH6235 and the article number 6890222 or SKU 6890222-Tungaloy to ensure the correct PVD-coated carbide grade and chipbreaker are supplied.
