CPMT050204-FM4 WMP20S – Rhombic 80° turning insert, FM4 chipbreaker (Walter Tools)

The CPMT050204-FM4 WMP20S is a rhombic 80° indexable turning insert optimised for stainless steel machining and medium to robust cutting conditions.

• Tiger‑tec Silver coating for reliable edge life
• FM4 chipbreaker for stable chip formation
• 11° clearance angle for smooth cutting
• Rhombic 80° form with 0.4 mm corner radius

Consistent chip control and predictable tool life

The combination of the WMP20S grade and the FM4 chipbreaker delivers controlled chip formation when machining stainless steel, reducing interruptions and improving machining security. The coated carbide substrate of the Tiger‑tec Silver series supports thermal stability and wear resistance under higher cutting temperatures, which helps to maintain a stable cutting edge over longer tool life. This results in fewer index changes and more consistent cycle times on turning centres and CNC lathes.

Geometry tuned for surface quality and repeatability

The rhombic 80° geometry with a 0.4 mm corner radius and an 11° clearance angle provides a balance between strength and accessibility in turning applications. The insert form allows secure engagement in shoulder and profile turning while the modest corner radius supports predictable surface finish without excessive cutting forces. The insert thickness and size coding ensure compatibility with standard toolholders designed for CPMT‑style chips, enabling straightforward tool setup and repeatable results across batches.

Practical integration and economic processing

Belonging to the Tiger‑tec Silver family, this coated indexable insert is designed for stainless steel under medium to robust conditions and aims to deliver high process reliability and stable chip control. The product’s specification supports productive machining by reducing unplanned downtime and simplifying tool inventory through a versatile grade selection. Where process security and surface quality are priorities, the insert provides a technically clear and cost-effective solution for serial production and single‑part machining alike.

FAQ

What materials is this insert suited for?
The CPMT050204-FM4 WMP20S insert from Walter Tools is intended primarily for machining stainless steel under medium to robust conditions, offering controlled chip formation and good edge stability.

Which chipbreaker is fitted and why does it matter?
This insert uses the FM4 chipbreaker; the FM4 geometry promotes stable chip formation and evacuation, which is especially beneficial when machining tough, ductile stainless steels.

How does the Tiger‑tec Silver coating influence performance?
The Tiger‑tec Silver coating on the WMP20S grade improves thermal resistance and wear behaviour, helping the Walter Tools insert maintain cutting-edge integrity and reduce index changes during longer cycles.

Is the insert compatible with standard CPMT toolholders?
Yes, the CPMT050204-FM4 form matches standard CPMT‑style toolholders; the rhombic 80° profile and coded size permit straightforward integration into common turning tool systems.

What surface finish can be expected with a 0.4 mm corner radius?
A 0.4 mm corner radius provides a compromise between strength and finish, delivering consistent surface quality on turned parts while maintaining adequate edge robustness for stainless steel applications.
