VCMT160404-PSS AH6235 – VCMT 160404 turning insert for turning applications, Tungaloy

The VCMT160404-PSS AH6235 is an ISO-standard rhombic indexable insert designed for metalcutting turning operations, especially where stainless steels and interrupted cuts require enhanced fracture resistance.

• ISO-standard rhombic geometry
• PVD-coated carbide grade AH6235
• 0.4 mm corner radius for precision
• Cylindrical hole with countersink

Longer tool life and controlled wear for demanding stainless work

The combination of a PVD-coated surface and the AH6235 carbide substrate provides improved resistance to built-up edge and thermal wear during turning of stainless steels and other tough alloys. This tougher grade is formulated for applications with elevated chipping risk and interrupted cuts, giving a measurable advantage in tool life and process stability. As a result, machining cycles can run longer between indexings, reducing downtime and contributing to predictable production output.

Geometry that delivers repeatable accuracy and surface quality

The rhombic insert form with a lead 35° angle and 7° clearance is optimised for both external and internal turning where edge integrity and surface finish matter. The small corner radius 0.4 mm helps to maintain dimensional control while allowing a compromise between strength and fine turning. The plate thickness of 4.76 mm ensures secure clamping and stability in the holder; compatibility relies on matching form, clearance, tolerance class, fastening and thickness to the selected toolholder for best results.

System approach and application guidance for practical machining

As part of an ISO insert system, the plate requires a suitable external holder or boring bar, appropriate shim/clamping kit and replacement screws for safe operation. The PSS chipbreaker is optimised for controlled chip formation with ductile materials and interrupted cuts, reducing the risk of built-up edge and improving swarf evacuation. Selecting the correct holder geometry and clamping method is essential for achieving the promised performance; technical specification and optimiser checks will align the insert’s advantages with the chosen machining strategy.
