TCMT16T312-RM4 WSM30S – Triangular turning insert (Tiger‑tec Silver) for stainless steels and superalloys | Walter Tools

The TCMT16T312-RM4 WSM30S is a triangular indexable turning insert engineered for secure chip control and durable cutting performance in applications on stainless steels, heat‑resistant superalloys and titanium.

• Tiger‑tec Silver coating for enhanced wear resistance
• WSM30S grade for stainless steels and superalloys
• RM4 chipbreaker for secure chip control
• 7° relief angle with 1.2 mm nose radius

High wear resistance for demanding alloys

The combination of the Tiger‑tec Silver coating and the WSM30S grade provides improved thermal stability and resistance to abrasive wear, which is particularly important when machining stainless steels and nickel‑based alloys. This engineered coating system supports stable cutting edges under elevated temperatures and reduces flank wear, enabling longer tool life and fewer indexings. The result is more predictable process windows and a lower frequency of tool changes, which benefits throughput in production environments.

Secure chip control and consistent edge behaviour

The RM4 chipbreaker is designed to ensure controlled chip formation during continuous turning, reducing the risk of long, entangling chips and improving surface finish consistency. The triangular 60° form combined with a 1.2 mm nose radius and 7° relief angle balances strength and precision: the geometry provides a robust cutting edge for medium to heavy cuts while maintaining the ability to achieve good surface quality. For shops aiming to minimise rework and machine downtime, this geometry supports repeatable performance and straightforward tool handling.

Application guidance for productivity and process stability

This insert is suitable for drilling/bore‑up and turning indexable applications where the workpiece materials fall into groups S and M (heat‑resistant superalloys/titanium and stainless steels). When paired with appropriate cutting parameters and a stable toolholder, the insert contributes to improved process security and consistent results. For best outcomes, align coolant strategy and feed/speed settings with the workpiece material class; tailored recommendations are available from technical advisors to help translate insert benefits into measurable productivity gains on the shop floor.
