DCMT11T304-FM4 WSM20S Indexable Insert (Rhombus 55°, 0.4 mm) – Walter Tools

A compact indexable insert designed for turning of stainless steel and hard-to-machine superalloys, offering Tiger·tec Silver coating and a dedicated chipbreaker for consistent machining results

• Tiger·tec Silver coated grade WSM20S
• For stainless steel and heat‑resistant alloys
• Rhombic 55° shape, 0.4 mm corner radius
• FM4 chipbreaker for stable chip control

Higher process security when machining tough alloys

The combination of the WSM20S grade and the Tiger·tec Silver coating is engineered for applications with high thermal and mechanical loads. This insert ensures stable chip formation and reduced tendency for build-up on the cutting edge when working with stainless steel and heat‑resistant superalloys, which often generate heat and strain the cutting zone. The result is improved machining consistency and fewer interruptions for edge dressing or insert changes, supporting predictable cycle times and production planning.

Geometry tuned for precision and surface quality

A rhombus 55° form with a 0.4 mm corner radius and 7° clearance provides a balance between robustness and fine surface finish. The FM4 chipbreaker is tailored to control chip flow and breakage in medium to finishing cuts, reducing the risk of snarled chips and tool mark formation. The insert thickness T3 and its ground seating face contribute to repeatable clamping and run-out behaviour, which together help to maintain consistent component tolerances and minimise rework.

Practical benefits across workshops and production lines

Designed for industrial turning, this indexable solution supports repeatable performance across batch and one-off production. The coated carbide grade extends usable edge life, while the chip control geometry reduces manual chip handling and associated cycle disruptions. As a brand known for precision, Walter Tools offers a robust portfolio and proven manufacturing quality—this insert is a technical option where reliability and predictable tool life contribute directly to operational efficiency.
