TCMT16T304-MW4 WKK20S — Indexable turning insert (triangle 60°, 0.4 mm radius) by Walter Tools

TCMT16T304-MW4 WKK20S is an indexable turning insert designed for efficient machining of cast iron components, combining a specialised chipbreaker and Tiger·tec Silver technology for reproducible performance in production turning.

• Tiger·tec Silver coating for high wear resistance
• Optimised for cast iron machining
• Triangle 60° form for secure clamping
• 0.4 mm corner radius for precise finishing

Higher productivity through tailored grade and coating

The WKK20S grade in the Tiger·tec Silver series is a coated cemented carbide developed specifically for the demands of cast iron. Its surface treatment improves resistance to the abrasive wear typical of grey and ductile castings, so machining cycles remain consistent over longer tool life. The result is fewer tool changes, more predictable production schedules and reduced downtime. Because the grade is tuned to cope with short, brittle chips common in cast iron, the machining process becomes more economical and stable in everyday turning operations.

Geometry and chip control for reliable surface quality

The triangle 60° geometry and 0.4 mm corner radius deliver a balance between strength and access to the cutting edge. The MW4 chipbreaker is engineered to form short, controlled chips during interrupted cuts and heavy cuts in casting materials, which reduces the risk of chip entanglement and improves process safety. A 7° clearance angle helps to avoid rubbing and supports a crisp cutting action, which in turn contributes to improved surface finish and dimensional consistency on each turned component.

Practical handling and integration into production

This indexable insert is supplied in the standard TCMT format and is compatible with indexable toolholders that accept the TCMT insert range; the T3 thickness ensures rigidity for many turning operations. For shops transitioning to a grade optimised for cast iron, the WKK20S insert offers straightforward implementation: its robustness reduces frequent regrinding, while predictable wear patterns simplify tool-change planning. For companies aiming to raise throughput without compromising component quality, this insert supports reproducible results in series production and jobbed work alike.

FAQ

Is this insert suitable for all types of cast iron?
The TCMT16T304-MW4 WKK20S is formulated for machining a wide range of cast-iron materials and performs well on abrasive grey and ductile cast iron within the ISO group K.

What is the benefit of the MW4 chipbreaker?
The MW4 chipbreaker on this Walter Tools insert produces short, controlled chips that reduce entanglement and improve process safety during turning of cast-iron components.

How does the Tiger·tec Silver coating help in production?
Tiger·tec Silver on the WKK20S grade enhances wear resistance against the abrasive nature of cast iron, extending tool life and ensuring more consistent machining results.

Can the insert provide a good surface finish with a 0.4 mm radius?
A 0.4 mm corner radius offers a compromise between edge strength and finishing capability; in many applications this geometry helps to achieve stable dimensional accuracy and an improved surface texture.
