Consistent chip control for stainless steel

The coated hardmetal composition of the WMP20G grade, part of the Tiger‑tec Gold series, is formulated to reduce built‑up edge and maintain a stable cutting edge when machining stainless steel. The combination of a coated carbide substrate and the tailored surface treatment improves wear resistance and thermal stability; this means fewer tool changes and a steadier surface finish under variable cutting conditions. For users less familiar with coating technology: the coating provides a hard, low‑friction layer that protects the substrate and helps evacuate chips reliably.

Productivity and process security in turning operations

The FM4 chipbreaker is designed to produce short, controllable chips in interrupted and continuous cuts, reducing the risk of entanglement and improving cycle times. The round RCMT geometry offers flexibility for different toolholders and cutting directions while the T3 thickness and 7° relief angle improve radial stability and minimise cutting forces. Together, these attributes support predictable tool life and consistent part quality, which is particularly important in batch production and when machining demanding rostfreie Werkstoffe.

Practical integration and application benefits

This indexable insert fits standard holders that accept RCMT forms and is suitable for a range of turning tasks on stainless steel, from roughing to finishing depending on cutting data. The insert’s balanced combination of grade and chip control reduces machine downtime and simplifies process setup, enabling shops to maintain throughput without sacrificing surface quality. For engineering teams seeking reliable inserts for rostfreie Werkstoffe, the WMP20G grade provides a technically sound choice backed by Walter Tools’ product engineering.
