DCMT11T308-FM6 WSM20S – Indexable turning insert, Tiger·tec Silver coating, FM6 chipbreaker (Walter Tools)

The DCMT11T308-FM6 WSM20S is a rhombic 55° indexable turning insert designed for machining stainless steels and heat‑resistant superalloys in demanding production environments

• Tiger·tec Silver coated for extended tool life
• Optimised FM6 chipbreaker for stable chip control
• Rhombic 55° form with 0.8 mm corner radius
• Suited to stainless steel and superalloys

Higher process stability through advanced coating and grade

The combination of the Tiger·tec Silver coating and the WSM20S grade offers significantly improved wear resistance when machining tough materials. The coating reduces thermal and abrasive wear, which helps maintain a stable cutting edge over longer tool life. For operations on stainless steel and heat‑resistant alloys, this means fewer interruptions for index changes and a more consistent dimensional result. The choice of grade is particularly beneficial where material adhesion and built‑up edge are common problems, since the microstructure and coating technology are designed to encourage predictable chip formation and reduced friction at the cutting zone.

Geometry engineered for secure chip formation and surface quality

The rhombic 55° insert form combined with a 0.8 mm corner radius and a 7° clearance angle gives a controlled engagement with the workpiece that supports both moderate feeds and stable finishing passes. The FM6 chipbreaker is optimised to produce short, manageable chips on difficult‑to‑cut alloys, improving machine safety and reducing manual chip handling. The geometry also helps protect the cutting edge from shock and excessive radial loads, which translates into improved surface integrity and reduced risk of rework. In practice, the geometry supports a balance of cutting forces that benefits both productivity and component finish.

Practical benefits, tolerances and reliable application

Tolerance class M and a plate thickness of T3 ensure repeatable seating and predictable performance when the insert is indexed. The insert’s DCMT11T308-FM6 designation denotes the specific form and fitment geometry compatible with standard tooling bodies, so integration into existing toolholders is straightforward. Because the insert is from Walter Tools and belongs to the Tiger·tec Silver series, it is aimed at production environments where consistent tool life and low variation are priorities. The design reduces downtime through fewer index changes and supports process repeatability, yielding economic advantages across production runs.
