DCMT070202-FM4 WSM30S – Turning insert for stainless steels and heat‑resistant alloys by Walter Tools

A DCMT070202-FM4 WSM30S indexable turning insert engineered for demanding applications in rostfreie Stähle and superalloys, offering stable edges and reliable chip formation

• Tiger·tec Silver coated grade WSM30S
• Optimised FM4 chipbreaker for secure chip control
• Rhombic 55° insert with 0.2 mm corner radius
• 7° relief and M tolerance for consistent seating

High‑performance grade for challenging materials

The WSM30S grade from the Tiger·tec Silver family is a coated carbide formulation developed specifically for materials that generate heat and tend to build up on the cutting edge. As a result, the insert supports reliable chip formation and sustained edge stability when turning rostfreie Stähle and heat‑resistant superalloys. This focus on thermal stability reduces the risk of accelerated wear and helps maintain dimensional accuracy across longer tool life, which in turn improves throughput and lowers overall machining costs.

Geometry designed for secure cutting and surface quality

The rhombic 55° shape combined with a 0.2 mm corner radius and a 7° relief angle provides a balance between entry strength and edge refinement. The FM4 chipbreaker is optimised to control chip flow in sticky, tough materials, preventing entanglement and minimising interruptions. With an M tolerance class for consistent seating, the insert delivers repeatable clamping accuracy and predictable machining behaviour—advantages that translate directly into fewer set‑up adjustments and a more stable production process.

Practical efficiency and recommended applications

Available in insert size 07 and thickness 02, this indexable insert suits a broad range of turning operations where process reliability matters. The combination of the coated grade and the FM4 geometry is particularly effective for continuous and semi‑continuous machining of rostfreie Stähle (ISO group M) and heat‑resistant superalloys (ISO group S), offering an economic solution for shops that require both performance and tool life. For customers seeking improved surface finish or reduced cycle times, the insert’s chip control and edge stability enable optimised cutting parameters and fewer interruptions for tool changes.

FAQ

What materials is this insert suited for?
The DCMT070202-FM4 WSM30S insert is designed for rostfreie Stähle (ISO group M) and heat‑resistant superalloys (ISO group S), providing stable cutting edges and reliable chip control in these materials.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker on the DCMT070202-FM4 WSM30S promotes controlled chip formation and evacuation, reducing the risk of chip entanglement and improving surface quality in difficult‑to‑machine alloys.

What are the key geometry benefits of the insert?
The rhombic 55° shape with a 0.2 mm corner radius and 7° relief offers a compromise between cutting edge strength and fine surface finish, while the M tolerance ensures consistent seating in standard toolholders.

Can this insert improve cycle times?
When paired with optimised cutting data, the WSM30S grade and FM4 geometry can enable higher productive cutting rates and fewer tool changes, contributing to reduced cycle times and increased overall efficiency.

Is the insert suitable for finishing operations?
Yes, the combination of the grade and the small corner radius supports improved surface finish in finishing passes on rostfreie Stähle and selected superalloys.
