DCMT11T304-FW4 (ISO: DCMT11T304-FW4) WSM20S — Drehwendeschneidplatte for stainless steel and superalloys by Walter Tools

The DCMT11T304-FW4 WSM20S is a rhombic 55° turning insert designed for reliable finishing and medium-heavy turning of stainless steel and heat-resistant superalloys, combining a coated carbide grade with an FW4 chipbreaker for controlled swarf formation

• Tiger·tec Silver coating for wear resistance
• FW4 chipbreaker for reliable chip control
• Rhombic 55° geometry for versatile turning
• Optimised for stainless steel and superalloys

Durable coating and material science for longer tool life

The combination of the WSM20S grade with the Tiger·tec Silver coating provides a balanced solution between wear resistance and edge toughness. As a coated carbide grade, it is engineered to withstand the thermal and adhesive stresses typical of stainless steel and nickel‑based alloys; the coating reduces flank wear and helps to delay edge breakdown. For production environments this means fewer insert changes and more predictable tool life, which directly contributes to higher machine uptime and lower unit costs.

Geometry and chip control that stabilise the process

The FW4 chipbreaker and the Rhombic 55° plate geometry work together to ensure consistent chip formation and evacuation. The chipbreaker is tailored to aid fragmenting or curling of swarf depending on cutting parameters, reducing the risk of entanglement and promoting stable cutting forces. The combination of a 7° relief angle and a 0.4 mm corner radius provides a compromise between edge strength and surface finish, supporting reliable machining under varying feed rates and depths of cut.

Designed for demanding materials and repeatable results

This insert is specifically specified for the ISO material groups M and S, making it suitable for stainless steel as well as heat‑resistant superalloys and titanium — materials that characteristically generate high temperatures and adhere to cutting edges. The grade and geometry promote safe chip control and a stable cutting edge, which helps to avoid built‑up edge formation and to maintain dimensional accuracy over series production. The overall design therefore supports process security and consistent part quality.

Practical handling and selection for workshop productivity

The DCMT format and the clear designation simplify inventory and toolholder selection in a production setting. The T3 plate thickness and the rhombic shape allow compatibility with a wide range of toolholders while the tolerance class M ensures interchangeability and repeatable seating. Selecting this insert family reduces the number of tool variants required for stainless steel and superalloy tasks, supporting streamlined tool management and faster changeovers on the shop floor.

FAQ

What materials is this insert suitable for?
The DCMT11T304-FW4 WSM20S insert by Walter Tools is specified for stainless steel (ISO group M) and heat‑resistant superalloys and titanium (ISO group S), offering thermal resilience and edge stability for those materials.

Which chipbreaker is fitted and what benefit does it provide?
The insert features the FW4 chipbreaker, which promotes controlled chip formation and reliable evacuation, reducing the risk of swarf-related interruptions during turning.

How does the corner radius affect performance?
A corner radius of 0.4 mm balances edge strength and surface finish; this radius supports durable edges under moderate depths of cut while helping to maintain dimensional accuracy.

Is this insert compatible with standard DCMT toolholders?
The DCMT format and T3 thickness align with industry DCMT toolholders; compatibility depends on the specific holder geometry and clamping method used.

What performance advantages does the Tiger·tec Silver series offer?
The Tiger·tec Silver coating on the WSM20S grade enhances wear resistance and thermal protection, leading to longer, more predictable insert life in demanding stainless steel and superalloy machining tasks.
