Increased productivity for cast iron turning

The combination of a CVD‑coated surface and a robust carbide substrate provides a dependable balance between wear resistance and edge strength. This results in fewer interruptions for tool changes and steadier component quality when machining cast iron, especially in interrupted cuts. The moderate 0.4 mm corner radius improves edge robustness while maintaining dimensional control, so cycle times can be optimised without sacrificing surface finish. For production environments seeking predictable tool life and repeatable results, this grade supports higher machining stability and lower per‑part tooling costs.

Secure seating and ISO compatibility for reduced setup time

The insert’s ISO 160404 designation and standardised geometry ensure straightforward compatibility with a wide range of external holders and boring bars. The triangular 60° geometry and the cylindrical hole provide reliable clamping and repeatable seating, which reduces setup variation and rework. Because the form, relief angle and tolerance class conform to ISO norms, integration into existing tooling systems is simplified and downtime for requalification is minimised—an operational advantage where fixture interchangeability and quick changeover are important.

Coating and substrate designed for longer service life

The T5115 specification is a universal CVD‑coated carbide grade developed for broad applicability in cast iron work. The chemical vapour deposition layer enhances resistance to abrasive wear and thermal loading, while the carbide core maintains a stable cutting edge under mechanical stress. The double‑sided nature of the insert effectively doubles available cutting edges per plate, improving cost efficiency. Additionally, the applied chipforming geometry contributes to controlled chip flow, reducing the risk of built‑up edge and improving surface integrity on finished components.

Practical application advice for efficient results

Select a holder and cutting parameters that match the insert’s geometry and the workpiece rigidity to exploit the chipbreaker and grade benefits fully. The TNMG format performs well with moderate feeds and cutting speeds typical for cast iron; the double‑sided layout and standard thickness support consistent performance across multiple seats. For interrupted cuts or less rigid setups, favour lower depths of cut and slightly reduced speeds to preserve edge life. When integrating into production, verify the holder seating face and clamping torque to maintain the ISO‑defined tolerances and ensure repeatable accuracy.

FAQ

What materials is this insert best suited for?
The TNMG160404 T5115 insert is optimised for cast iron machining; the T5115 grade provides a balanced combination of wear resistance and edge stability for this material.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius increases edge strength and reduces chipping risk compared with finer radii, improving durability in interrupted cuts while still enabling acceptable surface finish.

How many usable cutting edges does each insert provide?
The triangular, double‑sided design offers multiple indexed edges; the exact number depends on the insert orientation, but the format increases the service life per insert compared with single‑edged plates.

Which holders are compatible with this insert format?
Holders and boring bars that accept ISO TNMG160404 geometry with matching relief angle and clamping provisions will be compatible; correct seating and torque are essential for repeatable performance.

What is the benefit of the CVD coating on this grade?
The CVD layer enhances resistance to abrasive wear and thermal effects, extending edge life and stabilising cutting performance during longer production runs.
