Drehwendeschneidplatte CPMT04T104-MM4 WSM20S – rhombic 80° insert, Tiger·tec Silver coating, Walter Tools

The CPMT04T104-MM4 WSM20S is a rhombic 80° indexable insert designed for turning operations in stainless steels and heat‑resistant superalloys, offering a combination of thermal stability and secure chip control for demanding production environments.

• Tiger·tec Silver coating for thermal stability
• MM4 chipbreaker for secure chip control
• 11° relief angle for reduced cutting forces
• 0.4 mm corner radius, rhombus 80° form

Predictable chip control and extended edge life

The Tiger·tec Silver coating together with the MM4 chipbreaker provides a measurable improvement in heat resistance and chip formation, which reduces the risk of built‑up edge when machining ductile, work‑hardening materials. The coating technology increases thermal stability, helping the cutting edge retain its geometry under thermal load; this translates into longer tool life and fewer changeovers, improving throughput and lowering operating costs. The chipbreaker is specifically shaped to direct chips away from the cutting zone, which supports consistent surface finish and safer swarf handling.

Geometry optimised for stainless steel and superalloys

A combination of an 11° relief angle and a 0.4 mm corner radius in the rhombic 80° form provides a favourable balance between strength and cutting performance when turning stainless steels and heat‑resistant alloys. The moderate corner radius absorbs intermittent loads while maintaining a small contact area for lower cutting forces; this helps avoid workpiece distortion and improves dimensional stability. For shops processing corrosion‑resistant components or aerospace alloys, the insert’s geometry supports stable machining even under stringent tolerances.

Reduced downtime through consistent performance

The coated carbide grade WSM20S is engineered for applications classified under ISO groups M and S, meaning it is suited to stainless steel and heat‑resistant superalloys/titanium where thermal and abrasive stresses are high. Using this insert reduces the frequency of unexpected tool failures and the associated production stops. The stable cutting edge behaviour contributes to reproducible part quality and predictable tooling costs, allowing production planners to schedule maintenance and tool changes with confidence rather than reacting to premature wear.

FAQ

What materials is this insert intended for? The CPMT04T104-MM4 WSM20S is specified for ISO groups M and S — suitable for stainless steel and heat‑resistant superalloys/titanium when the geometry and cutting data are matched to the workpiece.

How does the Tiger·tec Silver coating benefit production? Tiger·tec Silver increases thermal stability at the cutting edge, so the Walter Tools insert maintains edge geometry longer and reduces wear rates when machining heat‑generating materials.

Which chipbreaker should be selected for continuous turning of ductile stainless grades? The MM4 chipbreaker on this insert is designed for secure chip control during turning of ductile and sticky materials, improving swarf evacuation and surface finish.

Can this insert be used for interrupted cuts or roughing operations? Yes — the rhombic 80° form with a 0.4 mm corner radius and the coated grade provide edge robustness that supports interrupted cuts and demanding roughing where thermal and mechanical loads occur.
