CCMT060204-FM4 WMP20S turning indexable insert — FM4 chipbreaker, 0.4 mm radius (Walter Tools)

The CCMT060204-FM4 WMP20S is a rhombic 80° indexable insert designed for medium to robust stainless-steel turning applications, combining a Tiger·tec Silver coating with a geometry that promotes stable cut conditions.

• Tiger·tec Silver coated carbide grade WMP20S
• Optimised for stainless steels (ISO M)
• FM4 chipbreaker for stable chip control
• 0.4 mm corner radius, 7° clearance angle

Consistent cutting performance for stainless steels

The coated WMP20S grade, part of the Tiger·tec Silver family, is engineered specifically for the challenges of stainless steels (ISO group M). The combination of a coated carbide substrate and a modern coating system improves thermal resistance and reduces edge build-up, which helps maintain a stable cutting edge over longer cycles. This results in fewer interruptions for edge dressing and a more predictable tool life under medium to robust cutting conditions, supporting continuity in production processes.

Predictable chip formation and improved surface finish

The FM4 chipbreaker is designed to generate controlled chip forms when tackling ductile, work-hardening materials. By shaping chips reliably, the breaker reduces the risk of entanglement and contributes to consistent surface quality. The 0.4 mm corner radius increases edge strength at the cutting tip, improving resistance to crater wear and reducing the chance of chipping during interrupted cuts. The rhombic 80° insert geometry further supports flexible turning strategies, enabling stable cutting directions with good access to workpiece features.

Practical fitment and workflow benefits in the workshop

Supplied in the established CCMT060204-FM4 format with a plate size 06 and thickness 02, this indexable insert integrates with common toolholder systems used for external turning. The standard clearance of 7° supports effective chip evacuation and helps to avoid rubbing at the flank. Stocking a consistent grade such as this simplifies tooling logistics and makes process planning more reliable for production shops and jobbing operations that require repeatable results on rostfreiem Stahl.
