TCGT110204-MK4 WKK20S turning insert — Tiger·tec Silver, for cast iron, Walter Tools

TCGT110204-MK4 WKK20S is a coated carbide turning insert engineered for productive machining of cast iron components, offering stable chip formation and wear resistance in short‑chipping materials

• Tiger·tec Silver coated substrate
• Optimised for cast iron (ISO K)
• MK4 chipbreaker for stable chips
• Triangle 60° form with 7° relief angle

Higher throughput through proven coating and chip control

The Tiger·tec Silver coating combined with the WKK20S grade provides a balance of abrasion resistance and toughness that suits abrasive cast iron work. This results in reduced flank wear and extended tool life under typical wet and dry cutting conditions. The MK4 chipbreaker is designed to produce predictable, short chips, which reduces interruptions and increases usable cutting time. For production runs in foundry components or engine parts, the measurable outcome is fewer tool changes and more consistent cycle times.

Consistent geometry for predictable machining performance

A triangle 60° insert shape with a 0.4 mm corner radius and 7° relief angle delivers reliable engagement and repeatable cutting forces. The standard form factor supports stable toolholding and consistent workpiece finish in turning operations. The coded thickness and size ensure compatibility with common toolholders for triangular inserts, enabling quick replacement and minimal set‑up time. This geometrical consistency helps maintain process windows and simplifies CNC programme validation.

Application clarity and material compatibility

Rated for the ISO group K (cast iron), this grade is tuned to the abrasive nature and typical brittle chip formation of cast materials. The substrate and coating pairing make this insert suitable for finishing and medium‑duty roughing where controlled chip breaking and surface quality are priorities. For shops seeking predictable results in cast iron, the combination of WKK20S grade and Tiger·tec Silver technology provides a clear, technical advantage without unnecessary complexity.
