VBMT 160408 AH6225 — ISO indexable turning insert for turning by Tungaloy

A VBMT160408-TSF AH6225 ISO indexable insert engineered for external and internal turning, optimised for machining rostfreier Stahl with a balance of sharpness and edge stability

• PVD-coated carbide grade AH6225
• Optimised TSF chipbreaker
• Compatible with ISO turning holders
• 35° lead angle and 0.8 mm nose radius

Greater productivity through a resilient cutting concept

The combination of a PVD-coated carbide substrate and the AH6225 grade delivers both wear resistance and a consistently sharp edge, enabling stable performance in medium cutting conditions. This balance reduces tool changes and stabilises cycle times, which translates into measurable productivity gains on the shop floor. The coated grade lowers friction and helps to manage thermal loads when machining rostfreier Stahl, so the result is improved tool life and fewer interruptions to production.

Reliable chip formation for safer, cleaner processes

The TSF chipbreaker is designed to produce controllable, short chips under a range of feeds, reducing the risk of entanglement and improving operator safety. Controlled chip flow also aids coolant access and supports a predictable surface finish on turned components. By combining the chipbreaker geometry with a low-friction coating, the insert minimises built-up edge and helps maintain dimensional consistency during longer runs, supporting higher first-pass yield and less rework.

Seamless integration with standard ISO systems

Compatibility is ensured by ISO sizing and key dimensional features: 16 mm inscribed size, 4.76 mm plate thickness, a 5° relief angle and a central hole with a cylindrical bore plus one-sided countersink for secure and repeatable clamping. These specifications align the insert with common outside holders and boring bars; the full system comprises the insert, a matching outer holder or boring bar, a backing shim/clamping kit and replacement clamp screws. Clear interface standards make tool set-up straightforward and reduce downtime when changing tools.

Practical guidance for typical turning applications

This insert is intended for external and internal turning under varying conditions where a sharp, stable edge is required—especially on rostfreier Stahl. The 0.8 mm nose radius and a 35° lead angle support a mix of general finishing and medium cutting tasks, delivering a balance between form accuracy and surface quality. Select feed and cutting data appropriate to the workpiece and machine rigidity; the insert’s design tolerates fluctuating conditions, giving a flexible option for mixed batches and small-series production.
