DCMT11T302-FW4 WSM20S indexable turning insert — Tiger·tec Silver, FW4 chipbreaker (Walter Tools)

The DCMT11T302-FW4 WSM20S is an indexable turning insert designed for robust finishing and semi-finishing of rostfreier Stahl and heat-resistant alloys in demanding turning operations.

Tiger·tec Silver coating for edge security
Optimised for rostfreie Stähle and superalloys
FW4 chipbreaker for controlled chip formation
Rhombus 55° form with 0.2 mm corner radius

Consistent edge life and higher process reliability

The combination of the WSM20S grade within the Tiger·tec Silver family provides a coated cemented-carbide solution engineered for heat resistance and stable cutting edges. This results in improved wear resistance and fewer unplanned tool changes, which supports steady production cycles. The coating technology reduces adhesive wear and thermal damage on the cutting edge, translating into predictable tool life and lower turnaround times for batch production. Technical terms such as coating thickness and substrate hardness refer to the material engineering that underpins this stability and are optimised for tough-to-cut groups.

Controlled chip formation for dependable machining

The FW4 chipbreaker geometry is designed to generate short, manageable chips even when tackling sticky or work-hardening materials. Controlled chip formation reduces the risk of built-up edge and improves coolant access at the cutting zone, which in turn helps maintain surface integrity and repeatable tolerances. The Rhombus 55° insert shape provides a versatile approach angle that balances cutting force and surface finish, while the 0.2 mm corner radius strengthens the edge against shock loads—advantages that improve component quality and reduce rework.

Broad suitability across demanding materials

This grade targets the material groups S and M: particularly heat-resistant superalloys, titanium and rostfreier Stahl. The insert’s design supports stable chip evacuation and heat management where conventional grades would blunt rapidly. For shops that machine mixed batches of high-temperature alloys and rostfreie Stähle, the insert offers a pragmatic compromise between edge robustness and surface quality. Where process windows are narrow, selecting a coated carbide grade such as this helps maintain throughput without sacrificing repeatability.

Efficient integration into production and measurable savings

With an insert thickness of T3, a 7° relief and compact 11 mm size, the item is compatible with many standard turning toolholders and toolpost setups, enabling quick replacement and minimal set-up time. The indexable format reduces overall tooling cost by allowing multiple edges per insert, while the optimised chipformer minimizes downtime for chip clearing. For technical assistance or to confirm compatibility with a specific holder or programme, Metav Werkzeuge can provide machining recommendations and cutting data to support integration into existing processes.

FAQ

What materials is this insert intended for?
The DCMT11T302-FW4 WSM20S insert is specified for rostfreier Stahl and heat-resistant superalloys (material groups M and S) where high temperatures and sticky chips demand a heat-resistant coated grade.

What does WSM20S signify?
WSM20S denotes Walter Tools’ coated carbide grade within the Tiger·tec Silver family; it is engineered for edge stability and wear resistance when machining challenging alloys.

How does the FW4 chipbreaker affect machining?
The FW4 chipbreaker produces short, controllable chips and aids coolant penetration, which improves surface finish and reduces the likelihood of built-up edge during machining with Walter Tools inserts.

Which geometrical values determine mounting and suitability?
Key values include the Rhombus 55° form, 11 mm size, 0.2 mm corner radius and 7° relief; these define toolholder compatibility and cutting behaviour for the insert.

Is this insert suitable for interrupted cuts or heavy roughing?
The coated grade and reinforced corner radius offer good resistance to edge damage; however, selection should be matched to specific cutting parameters—Metav Werkzeuge can provide tailored advice.
