VNMG120402E-TSF AH8015 indexable turning insert by Tungaloy — PVD-coated grade for heat-resistant alloys

VNMG120402E-TSF AH8015 is an ISO‑standard indexable turning insert designed for external and internal turning in demanding alloy work; the rhombic form and TSF chipbreaker support stable chip control.

• ISO‑compliant VNMG form for universal turning
• PVD‑coated AH8015 for heat‑resistant alloys
• TSF chipbreaker for controlled chip formation
• 0.2 mm corner radius for fine surface finish

Consistent cutting performance for heat‑resistant alloys

The combination of a PVD‑coated surface and the AH8015 carbide grade delivers a balanced mix of wear resistance and cutting‑edge stability, which is particularly important when machining heat‑resistant alloys. The indexable insert (VNMG120402E-TSF) is engineered to reduce flank and crater wear under intermittent and continuous cuts, translating into fewer indexings per job and improved process reliability. For machining environments where thermal load and abrasive wear are critical, the coated grade extends tool life while maintaining dimensional repeatability.

Geometry and chip control that improve surface quality

The rhombic form combined with the TSF chipbreaker and a 0.2 mm corner radius supports consistent chip formation and evacuation, which directly benefits surface integrity and reduces secondary finishing. The 35° lead angle and the 0° relief angle create a stable cutting direction that reduces radial cutting forces and vibration. These geometric characteristics make the insert suitable for light finishing passes and medium cutting conditions where a fine surface and tight tolerances are required. The effect is lower scrap rates and faster attainment of final dimensions.

System compatibility and practical handling

As an ISO‑standard turning insert, compatibility with toolholders depends on the insert’s shape, relief angle, tolerance class, fixation method, size and thickness. The insert is supplied in a rhombic form with a cylindrical locating hole, a nominal size of 12 mm and a 4.76 mm thickness, which simplifies selection of the corresponding external holder or boring bar. The modular system approach—insert, holder, clamping kit and replacement screws—permits quick index changes and standardised set‑ups across multiple machines, improving shopfloor uptime and inventory control.

FAQ

What materials is this insert suitable for?
The Tungaloy VNMG120402E-TSF AH8015 insert is specified as a first choice for machining heat‑resistant alloys, offering a balance between wear resistance and edge stability for demanding turning applications.

How does the TSF chipbreaker affect machining?
The TSF chipbreaker on this indexable insert promotes stable chip control and evacuation, which improves surface finish and reduces the risk of built‑up edge during medium and finishing cuts.

Which holders are compatible with this insert?
Compatibility is determined by the insert’s form, relief angle, tolerance class, fixation method, size and thickness; the rhombic VNMG form and cylindrical hole require holders designed for VNMG‑type inserts and the specified 12 mm inscribed size.

What dimensional details should be observed when replacing an insert?
Key dimensions for this insert are a 0.2 mm corner radius, 4.76 mm thickness, 12 mm size, 35° lead angle and 0° relief angle; matching these with the holder specifications ensures correct seating and repeatable performance.
