VNMG160404-SDM AH6235 — ISO turning insert (PVD-coated AH6235, SDM chipbreaker) by Tungaloy

The VNMG160404-SDM AH6235 is an ISO-indexable turning insert engineered for external and internal turning, optimised for stainless steels and interrupted cutting applications

• PVD-coated carbide grade AH6235
• Optimised for stainless steels and interrupted cuts
• SDM chipbreaker for reliable chip control
• 0.4 mm nose radius and 35° geometry

Improve process reliability in stainless steel turning

The combination of a PVD-coated surface with the AH6235 carbide substrate provides a tougher cutting edge that is less prone to built-up edge during the machining of stainless steels. This grade is formulated for interrupted cuts and situations with increased risk of edge breakout, so tool life is extended and fewer tool changes are required. The coating reduces friction and heat at the cutting zone, which translates into more consistent machining results and reduced cycle-time variability for production runs.

Consistent chip control reduces downtime

The SDM chipbreaker is designed to produce short, controllable chips under common turning conditions, which minimises chip tangling and the need for secondary clearing operations. With improved chip formation, coolant and workpiece contact remain predictable and tool holders experience less unexpected loading. This controlled chip behaviour supports stable unattended cycles and contributes directly to higher machine uptime and lower scrap rates in series production.

Secure mounting and rapid indexability for production environments

Compatibility with ISO toolholders is ensured by the standard ISO 160404 geometry and the rhombic insert shape; the insert is supplied with a cylindrical through-hole for positive clamping. With a 4.76 mm plate thickness and a 35° edge geometry, the insert offers a balance of rigidity and accessibility for both external and internal turning. The standard form and tolerance class allow quick indexing and reproducible seating in the clamping seat, so set-up time is reduced and process repeatability is improved.

Balance between surface finish and cutting edge strength

A 0.4 mm nose radius provides a useful compromise between strength and achievable surface finish: it supports robust cutting in soft to work-hardened stainless materials while still enabling acceptable roughness values for many finishing passes. The insert’s construction and coating strategy are chosen to give predictable wear patterns, which simplifies tool management and replacement scheduling in a production environment.
