CPMT050204-FM4 WMP20G — Indexable insert (Rhombus 80°, for stainless steel) | Walter Tools

The CPMT050204-FM4 WMP20G is an indexable insert engineered for turning and drilling operations in stainless steels, combining a coated carbide grade with an FM4 chipbreaker for stable chip formation under medium to robust conditions

• Tiger·tec Gold coating for extended tool life
• Optimised FM4 chip control for stainless steel
• Rhombic 80° geometry for versatile machining
• 11° relief angle reduces rubbing and heat build-up

Increased uptime through advanced coating technology

The insert’s Tiger·tec Gold technology provides a multi-layer coating specifically developed to resist the typical wear mechanisms encountered when machining stainless steel. By stabilising the cutting edge and reducing adhesion, the coating supports a longer tool life and fewer interruptions for index changes. For production environments this translates into improved process stability and a lower cost per component thanks to longer time between tool changes and consistent part quality.

Secure chip control and improved surface finish

The FM4 chipbreaker is tuned to the characteristics of materials in the ISO M group; it encourages short, controllable chips and reduces the risk of built-up edge that commonly affects stainless steels. This leads to a more predictable cutting process, better thermal management at the cutting zone and a more reliable surface finish, especially on critical components where repeatability is essential. Operators benefit from fewer interruptions and easier chip evacuation in both turning and light boring tasks.

Geometry designed for strength and flexibility

The Rhombus 80° shape combined with a 0.4 mm corner radius and an 11° relief angle balances edge strength with accessibility for machining operations. The geometry allows for both robust cuts and fine finishing passes while maintaining consistent contact conditions between insert and workpiece. As a result, the component quality remains high and tool indexing can be scheduled less frequently, supporting efficient batch production and predictable machining cycles.
