VNMG120412E-ZM AH8015 – VNMG 120412 turning insert for Drehen, PVD-coated, 1.2 mm radius (Tungaloy)

VNMG120412E-ZM AH8015 is an ISO-standard rhombic turning insert designed for external and internal turning, optimised for heat-resistant alloys and general-purpose turning applications.

• ISO rhombic VNMG form
• PVD-coated cemented carbide AH8015
• 1.2 mm corner radius for versatile turning
• Chipbreaker ZM for controlled chip formation

Predictable cutting in heat-resistant alloys for higher uptime

The PVD-coated cemented carbide grade AH8015 balances wear resistance with cutting-edge stability, making it suitable as a first choice for machining heat-resistant alloys. The coating increases surface hardness and reduces built-up edge, so the insert maintains consistent performance across longer tool life. By selecting a grade optimised for temperature resistance, process windows widen and unplanned tool changes are reduced, improving overall production efficiency.

Geometry and clamping designed for consistent compatibility

With a rhombic VNMG form, 1.2 mm corner radius and a 0° relief angle, the insert provides a stable cutting geometry that adapts well to a variety of turning tasks. The cylindrical hole and standard ISO dimensions ensure compatibility with common external holders and boring bars; compatibility depends on form, relief, tolerance class, clamping and thickness. Precise geometry supports repeatable results and reduces set-up time when replacing indexable inserts in multi-shift operations.

Chip control and edge security for smoother operations

The integrated chipbreaker ZM was developed to produce short, controllable chips when machining difficult-to-cut materials, lowering the risk of surface damage and machine stoppages. Combined with the robust PVD-coated substrate, the chipbreaker and edge preparation foster stable cutting even under variable cutting conditions. This yields improved surface finish and fewer secondary operations, supporting both cost-efficiency and reliable throughput.

Practical selection guidance for workshop and production planning

For general turning tasks, choose the AH8015 grade for a balanced compromise between tool life and edge robustness; consider the 1.2 mm radius for mixed roughing and finishing passes where versatility is required. When machining heavier workpieces or achieving specific surface roughness, pair the insert with a matching external holder rated for the VNMG form and verify clamping torque to secure consistent performance. The insert’s ISO conformity simplifies procurement and stock management.
