DCMT070202-FM4 WSM20S turning insert — Tiger·tec Silver, FM4 chipbreaker (Walter Tools)

A DCMT070202-FM4 WSM20S indexable turning insert designed for reliable performance when machining stainless steel and high-temperature alloys in demanding turning operations

• Tiger·tec Silver for thermal stability
• Suitable for stainless steel and superalloys
• Rhombic 55° geometry for stable cutting
• 0.2 mm corner radius for fine surface finish

High thermal resistance for consistent metal removal

The Tiger·tec Silver coating, combined with the coated carbide grade WSM20S, delivers enhanced heat resistance and wear properties for turning applications. This formulation stabilises the cutting edge under high temperatures and reduces the risk of edge build-up when machining tough materials. For operations involving stainless steel or heat-resistant alloys, the result is improved process reliability and more predictable tool life, which supports steady production cycles and reduced downtime.

Geometry and edge definition that improves surface quality

The rhombic 55° insert form and the 0.2 mm corner radius provide a balance between strength and finish capability. This geometry promotes a controlled engagement angle that reduces radial cutting forces and helps maintain a consistent surface finish on the workpiece. With a 7° relief angle and medium tolerance class M, the insert is suited to standard turning set-ups where dimensional reliability and repeatable edge performance are required.

Chip control and material coverage for efficient machining

Equipped with the FM4 chipbreaker, the insert supports secure chip segmentation and evacuation across a range of feeds and depths of cut. The designation S / M indicates suitability for superalloys (S) and stainless steel (M), so the insert covers a broad material spectrum common in aerospace, medical and energy sectors. The robust chip control combined with a stable cutting edge helps to reduce cycle times and increases process productivity while preserving component quality.

FAQ

What materials is this insert suitable for?
The DCMT070202-FM4 WSM20S insert is formulated for stainless steel (M) and heat-resistant superalloys (S), with the Tiger·tec Silver coating supporting thermal stability during heavy-duty turning.

How does the FM4 chipbreaker affect performance?
The FM4 chipbreaker on the DCMT070202-FM4 WSM20S promotes controlled chip formation and evacuation, improving process security and helping to maintain consistent surface quality in continuous turning operations.

What surface finish can be expected with a 0.2 mm corner radius?
A 0.2 mm corner radius delivers a fine finish while preserving edge strength; on the DCMT070202-FM4 WSM20S this radius provides a reliable compromise between component quality and insert durability.

Is this insert suitable for finishing and semi-finishing operations?
Yes. The combination of rhombic 55° geometry and a small corner radius makes the insert versatile for semi-finishing and finishing passes where dimensional control and surface integrity are important.

Which series and grade does the insert belong to?
The insert is part of the Tiger-tec Silver series and uses the WSM20S coated carbide grade, optimised for tough-to-machine materials and applications requiring stable cutting edges.
