TNMG160408-MW5 WKK10S — Turning insert, Tiger·tec Silver, for cast iron — Walter Tools

A TNMG160408-MW5 WKK10S triangular turning insert designed for productive machining of cast iron, combining a wear-resistant coating with a robust chipbreaker and neutral-to-negative rake.

• Tiger·tec Silver coating for extended tool life
• WKK10S grade optimised for cast iron machining
• Triangle 60° with 0.8 mm corner radius
• MW5 chipbreaker for stable chip formation

Longer tool life and consistent wear performance for cast-iron turning

The combination of the Tiger·tec Silver coating and the WKK10S carbide grade is engineered to resist abrasive wear typical of cast iron machining. The advanced coating reduces flank and crater wear while maintaining edge stability under interrupted cuts. For production environments where predictable tool life is essential, this turning insert offers a measurable improvement in process consistency. The improved wear behaviour means fewer insert changes and less unplanned downtime, which contributes directly to shop-floor productivity and lower operating cost per component.

Geometry and cutting-edge strength that support reliable productivity

The triangular 60° geometry provides three usable cutting corners per insert, extending usable life before indexing. A 0.8 mm corner radius increases edge robustness for roughing and general-purpose turning, while the 0° (negative) relief angle yields a neutral-to-strengthened cutting edge suited to tough, brittle cast-iron chips. The integrated MW5 chipbreaker is tuned for the short, brittle chips produced from cast iron, promoting secure chip control and reduced risk of chip entanglement. The result is a stable cutting process that supports higher feed rates and steady surface finishes.

Practical benefits in process engineering and shop-floor handling

Using a graded insert with a defined chipbreaker and coating simplifies process set-up: the geometry supports repeatable results on typical cast-iron grades, while the coating extends performance across batch runs. The insert’s designation and series make it straightforward to match to tooling holders and machine capability, enabling quick substitutions during scheduled maintenance. For engineers seeking to reduce variation, the combination of coating technology and chip control lowers scrap rates and stabilises cycle times, supporting reliable throughput in turning centres and lathes.

Clear application guidance and material compatibility

This insert is specified for cast iron workpieces (material group K) and is delivered in the recognised TNMG format for triangular indexable inserts. Its MW5 chipbreaker and the Tiger·tec Silver technology make it particularly suitable for abrasive and discontinuous cast-iron surfaces. When selecting cutting parameters, favour conservative depth of cut and appropriate feed to exploit the insert’s edge strength; consult tooling tables or Metav Werkzeuge for suggested starting values. The indexable design provides straightforward re-use of toolholders and predictable inventory management.

FAQ

What materials is this insert intended for?
The TNMG160408-MW5 WKK10S insert is designed for machining cast iron (material group K) and performs best where short, brittle chips are expected.

How does the Tiger·tec Silver coating benefit tool life?
The Tiger·tec Silver coating on the WKK10S grade reduces abrasive wear and improves edge stability, extending service life of the turning insert in abrasive cast-iron operations.

What is the significance of the MW5 chipbreaker?
The MW5 chipbreaker is tuned to control the short, fractured chips typical of cast-iron turning, improving chip evacuation and reducing the chance of chip-related issues in the machining zone.

How many cutting edges are available per insert?
The triangular 60° geometry gives three indexable cutting corners, allowing multiple repositions before disposal.

Is this insert compatible with standard TNMG toolholders?
Yes, the insert follows the TNMG ISO designation and fits holders specified for TNMG inserts; verify holder compatibility and clamping style before installation.
