Consistent cutting in stainless steel with Tiger·tec Silver

The Tiger·tec Silver technology and the WMP20S carbide grade deliver a balance of wear resistance and toughness that supports stable chip formation when machining stainless steel (ISO M). This coating technology reduces built-up edge and extends cutting life under elevated temperatures typical for these materials. Where thermal load and material ductility can cause inconsistent chips, the FM4 chipbreaker assists in producing controllable, segmented chips, which lowers the risk of re-cutting and improves cycle reliability. The result is fewer tool changes and a steadier production flow.

Geometry engineered for surface quality and tool life

The rhombic 55° form and a 0.8 mm corner radius offer an effective compromise between strength and finish. The insert’s 7° relief reduces rubbing at the flank, while the T3 thickness contributes to rigidity in interrupted or heavier cuts. Together, these geometric features reduce vibration and distribute cutting forces more evenly, which enhances both tool life and part surface quality. For components where a finer finish is required, the geometry supports lower feed rates without sacrificing edge stability.

Practical benefits for workshop productivity

The combination of a coated carbide grade, robust chip control and standard DCMT clamping compatibility simplifies integration into existing turning setups. The FM4 chipbreaker is tailored to the workpiece behaviour of stainless steels, promoting predictable chip shapes that ease handling and swarf management. As a result, tool-setting times and unplanned stoppages are reduced, delivering measurable efficiency gains across short and long production runs. The insert is suitable for medium to robust applications where process consistency is prioritised.
