Take advantage of the PVD-coated carbide AH6235 for improved resistance in interrupted cuts and the 0.8 mm corner radius for fine contouring; order the insert directly via Metav Werkzeuge or consult our specialists for application-specific holder matching.

VCMT160408-PS AH6235 ISO turning insert — PVD-coated carbide, 0.8 mm corner radius (Tungaloy)

The VCMT160408-PS AH6235 is an ISO-format turning insert designed for external and internal turning, optimised for interrupted cuts and demanding stainless steel applications

• PVD-coated carbide grade AH6235
• 0.8 mm corner radius for fine contours
• Cylindrical hole with 40°–60° countersink
• ISO rhomboid form VCMT160408-PS

Consistent chip control and extended edge life for stainless steel turning

The combination of a PVD-coated surface and the AH6235 carbide grade gives the insert a tougher cutting edge that copes well with work-hardened and corrosive materials such as stainless steel. For operations with frequent engagement and disengagement, the chipbreaker PS moderates chip formation, reducing the risk of edge fracture during interrupted cuts. The result is a measurable improvement in process reliability and longer interval between insert changes, which supports steady production and lowers tooling-related downtime.

Geometry that guarantees stable clamping and repeatable results

The ISO rhomboid geometry with a 0.8 mm corner radius and a 7° rake clearance ensures predictable contact conditions in the pocket — important for repeatability in serial turning. The insert is supplied with a cylindrical hole and a single-side countersink (40°–60°) to accommodate standard clamp designs; plate thickness is 4.76 mm, and the nominal size is 16 mm, matching ISO holder specifications. These defined dimensions simplify holder selection and minimise assembly time, allowing fast replacement without compromise to concentricity or rigidity.

Easy integration into existing tooling systems and clear selection logic

As part of a standard ISO insert system, this model fits typical external holders or boring bars when form, rake, tolerance class, fastening and thickness match. Choosing the correct chipbreaker and grade — as shown with AH6235 and PS — aligns cut stability with material demands, especially where breakout risk or interrupted machining is present. The clear specification of the insert simplifies inventory management and supports efficient machining strategies, delivering a convincing cost-benefit via longer life and stable surface finish.

FAQ

What materials is this insert best suited for?
The VCMT160408-PS AH6235 is optimised for stainless steel and applications with interrupted cuts, thanks to the tougher AH6235 grade and PVD coating.

How does the chipbreaker PS influence performance?
The PS chipbreaker controls chip flow to reduce edge stress during interruptions, improving stability and lowering the risk of edge breakouts for this Tungaloy turning insert.

Which holder features are required for correct compatibility?
Compatibility depends on form, free angle, tolerance class, fastening method, size and thickness; ensure the holder matches the ISO VCMT160408 profile, 4.76 mm thickness and the cylindrical hole with countersink.
