• Double-sided chipbreaker, with cylindrical hole

High-efficiency turning with controlled chip formation

The combination of a CVD-coated carbide substrate and the T515 grade provides a balance between tool life and cost-efficiency for cast-iron applications. The coating enhances wear resistance at typical cutting speeds for cast iron, while the substrate maintains toughness during interrupted cuts. Because the insert features a double-sided chipbreaker, chip control is consistent across a range of feeds, which reduces cycle times and minimises secondary operations. This makes the insert particularly suitable for production environments where predictable performance and low tooling costs are priorities.

Stable geometry that supports consistent surface finish

The 60° triangular geometry and 0.8 mm corner radius contribute to a stable cutting edge that resists deformation under load. A larger corner radius improves tool strength and can deliver better surface quality when process parameters are stable; conversely, the modest radius still allows for effective finishing passes where required. The 4.76 mm thickness adds rigidity to the cutting edge, reducing vibration in less rigid setups and supporting repeatable dimensional results. These geometric attributes are especially beneficial when machining cast iron components that demand both productivity and repeatable surface integrity.

Practical system compatibility and selection guidance

Compatibility with toolholders is determined by form, relief angle, tolerance class, clamping method, size and thickness, so matching the insert profile to the holder is essential. The insert carries a cylindrical hole for secure clamping and is part of an ISO turning insert system; this simplifies replacement and inventory management across standard holders. Select the chipbreaker and grade according to workpiece stability and the nature of the cut — continuous cuts benefit from smoother chip flows, while interrupted cuts require a tougher edge. For complex applications or mixed-batch production, advisers at Metav Werkzeuge can recommend the best holder–insert combination and process parameters.

FAQ

What materials is this insert optimised for?
The TNMG160408 T515 is optimised for economical machining of cast iron, using its CVD-coated carbide grade to combine wear resistance with toughness for typical turning operations.

How does the corner radius affect cutting results?
A 0.8 mm corner radius increases edge strength and promotes a consistent surface finish in stable cutting conditions; the radius is a compromise between robustness and the ability to produce finer finishes.

Is the insert compatible with standard ISO holders?
The insert follows ISO specifications for turning inserts; compatibility depends on holder form, tolerance and clamping — matching these parameters ensures correct seating and secure clamping.

What purpose does the double-sided chipbreaker serve?
The double-sided chipbreaker maintains effective chip control across both indexed orientations, extending usable life per insert and aiding continuous production runs with reduced manual intervention.

Which coating and substrate are used on the insert?
The insert uses a CVD-coated carbide substrate in the T515 grade, offering a balance of wear resistance and toughness suited to cast-iron turning.
