CNMG120404-MM5 WSM30S indexable turning insert for stainless steels and superalloys — Walter Tools

The CNMG120404-MM5 WSM30S is an indexable turning insert optimised for machining rostfreie Stähle and heat‑resistant superalloys, offering a robust geometry for reliable production machining.

• Tiger·tec Silver coating for wear resistance
• Optimised for rostfreie Stähle and superalloys
• Rhombic 80° shape with 0.4 mm corner radius
• MM5 chipbreaker for controlled chips

Longer tool life and consistent cutting on demanding alloys

The combination of the Tiger·tec Silver coating and the WSM30S carbide grade delivers wear resistance and thermal stability in continuous production environments. Coated carbide provides a hard outer layer that resists abrasion while the substrate retains toughness; this reduces edge breakdown and extends service intervals. For shops working with rostfreie Stähle and heat‑resistant alloys, that means fewer tool changes, less unplanned downtime and improved machine availability. The result is a measurable increase in process reliability and predictable component quality under challenging cutting conditions.

Predictable chip control and improved surface finish

The Rhombic 80° geometry combined with a 0.4 mm corner radius and the MM5 chipbreaker produces stable chip formation and consistent cutting forces. A negative clearance angle of 0° (negative rake) supports a robust cutting edge, which is particularly advantageous when dealing with sticky materials that tend to build up on the tool. Stable chip control reduces entanglement and improves swarf evacuation, helping to protect the workpiece surface and the toolholder. This geometry is suited to applications where a balance of edge strength and surface integrity is required, giving a reliable finished surface with minimal rework.

Seamless integration into productive turning operations

Designed to fit ISO CNMG indexable toolholders, the insert’s standard form factor simplifies integration into existing toolsets and fixtures. The MM5 chipbreaker and the coated grade enable versatile use across finishing and more demanding semi‑finishing tasks, supporting higher cutting parameters where process security is essential. Walter Tools’ engineering focus on consistent cutting edge quality promotes repeatable performance across batches, which supports lean production goals. When combined with appropriate toolholder selection and cutting data, this insert contributes directly to higher throughput and lower overall machining costs.

FAQ

What materials is this insert suited for?
The CNMG120404-MM5 WSM30S insert is specified for rostfreie Stähle and heat‑resistant superalloys, making it suitable where thermal and adhesive tool wear are primary concerns.

How does the MM5 chipbreaker affect machining?
The MM5 chipbreaker on this Walter Tools insert promotes short, controlled chips and steady cutting forces, which improves swarf evacuation and reduces the risk of workpiece damage.

Is the insert compatible with standard CNMG toolholders?
Yes, the CNMG120404-MM5 geometry follows ISO CNMG conventions and fits standard CNMG indexable toolholders when the holder matches the insert size.

What advantage does the Tiger·tec Silver technology provide?
Tiger·tec Silver coating enhances wear resistance and thermal stability on the cutting edge; for the WSM30S grade this means improved tool life and more stable cutting under elevated temperatures.

Can this insert be used for finishing and semi‑finishing operations?
The combination of the 0.4 mm corner radius and MM5 chipbreaker makes the insert versatile for both finishing and certain semi‑finishing tasks, depending on cutting data and workpiece material.
