Optimised MM4 chipbreaker for stable chips
Rhombic 80° geometry for versatile cutting
7° clearance and 0.4 mm corner radius

High‑temperature stability and edge reliability for demanding alloys

The Tiger·tec Silver grade WSM20S combines a coated carbide substrate with a chemistry tuned for heat resistance and controlled wear, delivering consistent edge stability during prolonged engagement. In practice, this means improved process security when machining rostfreier Stahl or heat‑resistant superalloys and titanium: the coating reduces temperature peaks at the cutting edge while the carbide core supports mechanical strength. The technical advantage is fewer unscheduled insert changes and a steadier surface quality, translating into measurable gains in machining throughput and predictable tool life.

Geometry and chip control that support productive turning and drilling

The rhombic 80° insert form with 7° clearance and a 0.4 mm corner radius offers a balance between strength and accessibility in both radial and axial operations. Paired with the MM4 chipbreaker, the geometry produces short, controllable chips across interrupted cuts and continuous turning, improving swarf evacuation and protecting the cutting edge. For integrators and process planners, these features mean reduced tool‑related stoppages and more consistent component finish, especially in operations where chip shape and evacuation are critical for cycle time and machine safety.

Production compatibility and handling for workshop efficiency

Designed as an indexable insert of size 09 and thickness T3, this item fits common clamping systems where CCGT‑style inserts are specified and benefits from a tolerance class G for repeatable seating and clamping. The WSM20S grade is specified for machining categories M and S according to ISO 513, so material grouping and process planning are simplified: one insert covers rostfreier Stahl and selected heat‑resistant alloys depending on the application geometry. The result is fewer tool variants to manage, straightforward inventory decisions and easier tool‑life forecasting.
