VNMG 120408 T9215 – VNMG ISO indexable turning insert for turning by Tungaloy

VNMG120408E-PS T9215 is an ISO-standard indexable insert designed for turning applications, offering a balance of wear resistance and fracture toughness for productive medium-steel machining.

• CVD-coated carbide grade T9215
• Suited for medium steel machining
• Rhombic insert, 12 mm size
• 0.8 mm corner radius, 0° clearance

Consistent productivity for medium-steel turning

The combination of a CVD-coated surface and a carbide substrate in grade T9215 delivers a reliable balance of wear resistance and fracture toughness. This makes the insert particularly effective in continuous and lightly interrupted operations, where tool life and predictable wear behaviour translate directly into reduced downtime and fewer insert changes. The grade is optimised to sustain higher material removal rates while maintaining surface quality, so production runs benefit from steady cycle times and lower tooling costs per part.

Geometry that simplifies set-up and improves surface finish

Thanks to the rhombic ISO form and a precisely ground 0.8 mm corner radius, the geometry produces a controlled cutting edge that eases setup and improves dimensional stability in turned components. The 0° clearance and the defined 35° wedge angle contribute to consistent contact conditions between insert and workpiece, reducing chatter and enhancing surface finish. For shops that value repeatability, this geometry reduces rework and shortens inspection intervals.

Designed for compatibility with ISO toolholders

Compatibility with the toolholder is governed by form, clearance, tolerance class, fastening method, size and thickness; this insert’s ISO-standard dimensions (size 12, thickness 4.76 mm) and cylindrical hole allow straightforward mounting in a wide range of external holders and boring bars. Selecting the correct holder and clamping set ensures secure seating and correct rake geometry, which in turn preserves tool life and process stability. The insert therefore integrates readily into established turning setups.

Chip control and application range

The PS chipbreaker geometry supports reliable chip formation for medium steels, easing evacuation during turning and lowering the risk of recutting. The insert’s design is especially suitable for finishing to medium roughing operations where a balance between metal removal rate and surface quality is required. When matched with appropriate cutting data and stable workholding, this insert helps achieve consistent part tolerances and efficient cycle times.
