Order inserts directly via Metav Werkzeuge or consult the technical team for holder matching. CNMA 160612 T5105 Tungaloy turning insert (ISO CNMA160612) — CVD-coated carbide, R1.2 The CNMA160612 T5105 is an ISO turning insert engineered for stable high-speed machining of cast iron in external and internal turning applications. CVD-coated carbide for high wear resistance ISO CNMA160612 rhombic insert, 80° geometry R1.2 corner radius for finishing and semi-finishing Cylindrical central hole for secure clamping Stable high-speed performance for cast iron The CVD-bonded grade T5105 is formulated for wear resistance during high cutting speeds, which supports longer tool life under steady machining conditions. The rhombic, 80° geometry provides a predictable cutting angle that reduces vibration in many lathe set-ups, meaning the insert maintains edge integrity for longer when machining cast iron. This results in fewer insert changes per shift and a more continuous production flow, both of which contribute to process reliability and reduced downtime. Precise fit, secure clamping and repeatability Compatibility with toolholders depends on form, clearance angle, tolerance class, mounting and the plate’s dimensions; the CNMA format and cylindrical hole enable positive clamping and repeatable positioning. The plate thickness of 6.35 mm and the nominal size 16 provide a stable contact surface, while the 0° relief ensures the intended rake and clearance are preserved when paired with matching holders. These characteristics reduce runout and support consistent surface finish across batches. Why the material and coating matter The insert’s carbide substrate with a CVD coating offers a balanced combination of toughness and thermal resistance. CVD layers increase resistance to abrasive and diffusion wear at elevated temperatures typical of high-speed turning, so chip formation remains stable and flank wear is delayed. For operations where repeatable dimensional control and surface quality are required, this coated carbide option enables higher cutting speeds compared with uncoated grades, while preserving dimensional stability on cast-iron components. Practical application and assembly guidance With an R1.2 corner radius the insert suits finishing and light semi-finishing passes, delivering a controlled edge for improved surface quality. The absence of a dedicated chipbreaker on this insert means the chip control strategy must be selected according to workpiece geometry and machine rigidity; pairing the insert with an appropriate holder, or a suitable shim/clamp set and replacement screws, completes the system. The recommended system components are the ISO turning insert itself, a compatible external holder or boring bar, and the matching shim/clamp set to ensure secure engagement and repeatable clamping accuracy.
