DCMT070204-FW4 WSM20S – Turning insert, Tiger‑tec Silver coating, 7° clearance (Walter Tools)

The DCMT070204-FW4 WSM20S is a rhombic 55° turning insert with a dedicated FW4 chipbreaker, designed for productive turning of stainless steel and heat‑resistant superalloys in demanding machining environments.

• Tiger·tec Silver coating for high heat resistance
• Optimised chipbreaker FW4 for secure chip control
• Rhombic 55° form with 0.4 mm corner radius
• Suitable for stainless steel and superalloys

Consistent cutting-edge performance for demanding alloys

The combination of WSM20S grade carbide and the Tiger‑tec Silver coating delivers improved heat resistance and a stable cutting edge, reducing the tendency to build up material during interrupted cuts. This grade is formulated for materials classified as M and S, specifically stainless steel and heat‑resistant superalloys, where thermal load and edge stress are high. By choosing this coated turning insert, process stability is increased and tool-change intervals are more predictable, which supports steady productivity in serial production.

Geometry engineered for predictable surface finish

The rhombic 55° geometry and a 0.4 mm corner radius provide a balance between edge strength and achievable surface quality. The 7° clearance reduces rubbing on the flank face, which helps to maintain dimensional accuracy and consistent part finish over longer cycles. For shops converting from general‑purpose grades, the defined geometry minimises the need for excessive feed reductions while maintaining process reliability.

Secure chip control that supports cycle time reduction

The FW4 chipbreaker is optimised for controlled chip formation in tough materials, guiding chips away from the cutting zone and reducing downtime caused by entanglement or recutting. Stable chip evacuation contributes to repeatable tool life and safer automated operation. In combination with the coated grade and robust edge, this insert supports higher cutting parameters where the machine and setup allow, offering a concrete route to improved throughput.

Simple integration and selection advice for metalworking shops

The insert’s designation and form fit standard toolholders for rhombic 55° carbide inserts, enabling straightforward integration into existing turning setups. For choice of cutting parameters, base feeds and speeds on material group, rigidity and coolant use; the coating and grade allow a bias towards higher thermal stability settings. If machining stainless steel or nickel‑based alloys is a recurring requirement, this insert offers a clear technical advantage in edge life and process security.

FAQ

What materials is this insert suitable for?
The DCMT070204-FW4 WSM20S insert is designed for stainless steel and heat‑resistant superalloys (material groups M and S), providing enhanced edge stability under high thermal load.

How does the FW4 chipbreaker improve machining?
The FW4 chipbreaker on the DCMT070204-FW4 WSM20S promotes controlled chip formation and evacuation, which reduces the risk of chip entanglement and supports more consistent cycle times.

Which features help to prevent built‑up edge when turning stainless steel?
The combination of the WSM20S grade and Tiger‑tec Silver coating improves heat resistance and reduces adhesion, helping to prevent built‑up edge during stainless steel turning.

Is the insert compatible with standard rhombic 55° toolholders?
Yes, the rhombic 55° form and standard dimensions of the DCMT070204-FW4 WSM20S allow direct fitting into conventional holders designed for that geometry.

What does the tolerance class M indicate for this insert?
Tolerance class M denotes the machining accuracy and manufacturing tolerances of the insert; for the DCMT070204-FW4 WSM20S this supports reliable, repeatable positioning in the toolholder.
