DCMT11T308-MM4 DCMT11T308-MM4 WMP20S — Turning insert for stainless steel, Walter Tools

A high-performance DCMT11T308-MM4 WMP20S indexable turning insert designed for medium to heavy machining of stainless steel, combining a wear-resistant coating with a geometry tuned for stable chip formation.

• Tiger·tec Silver coating for process security
• Optimised MM4 chipbreaker
• 7° clearance for stable cutting
• 0.8 mm corner radius for edge strength

Consistent cutting performance with advanced coating

The Tiger·tec Silver coating and the grade WMP20S deliver a consistent tool life under the demanding conditions associated with stainless steel. The coated carbide substrate supports secure chip control, reducing the risk of built-up edge and enabling more predictable tool changes. This combination is particularly suited to applications where material ductility and heat generation can otherwise compromise surface finish and edge stability. The result is fewer rejects and a smoother production flow.

Geometry engineered for strength and reliability

A rhombus 55° shape with a 0.8 mm corner radius and 7° relief provides a balance between cutting robustness and accessibility for varied turning tasks. The moderate corner radius increases edge life during interrupted cuts and hard-facing zones, while the clearance angle helps maintain a constant cutting line. The integrated MM4 chipbreaker promotes short, controllable chips across common stainless steels, which eases chip evacuation and reduces machine downtime for cleaning.

Process benefits and application guidance

Designed for machining stainless steel in medium to robust conditions, this indexable insert supports higher reproducibility and less variation in batch production. The coated grade is aimed at operators seeking both improved surface quality and stable tool life in serial or single-piece manufacturing environments. For implementation, use holders compatible with the DCMT form and select feeds and speeds aligned with the workpiece alloy and rigidity of the setup; technical parameter support is available if required.

FAQ

What materials is this insert best suited for?
The DCMT11T308-MM4 WMP20S turning insert is specified for machining stainless steel, where the WMP20S grade and Tiger·tec Silver coating support stable chip formation and reduced built-up edge.

How does the MM4 chipbreaker affect performance?
The MM4 chipbreaker on this insert produces short, controlled chips during turning of stainless steels, improving chip evacuation and reducing the likelihood of entanglement in the machining area.

Can this insert handle interrupted cuts or roughing operations?
Yes, the 0.8 mm corner radius and robust geometry are designed to withstand interrupted cuts and more aggressive turning, offering improved edge strength and repeatable performance.

Which insert shape and holder compatibility should be considered?
The rhombus 55° form (DCMT) requires holders designed for DCMT inserts; selecting a rigid toolholder reduces vibration and allows the coating and geometry to deliver the intended tool life.

Is the coating suitable for high-temperature conditions during turning?
The Tiger·tec Silver coating enhances wear resistance and thermal stability, making the grade appropriate for the elevated temperatures commonly encountered when machining stainless steels.
