DCMT070204-RM4 WSM20S indexable turning insert, Tiger·tec Silver, for rostfreier Stahl and superalloys (Walter Tools)

The DCMT070204-RM4 WSM20S is a rhombic 55° indexable turning insert engineered for heavy and semi-finish turning of rostfreier Stahl and heat-resistant superalloys in industrial machining.

Tiger·tec Silver coated cemented carbide
Optimised for rostfreier Stahl and superalloys
7° clearance angle for secure cutting
0.4 mm nose radius for defined finish

High‑performance grade for difficult-to-machine alloys

The Tiger·tec Silver coating, combined with a coated cemented carbide substrate, provides improved thermal resistance and edge stability for prolonged tool life. Designed specifically for machining rostfreier Stahl and superalloys, this cutting grade supports a secure chip formation process under elevated temperatures. The result is consistent cutting behaviour and reduced risk of built‑up edge when compared with uncoated grades, which helps maintain productivity and reduces unplanned tool changes.

Reliable geometry for predictable surface quality

A rhombic 55° geometry with a 0.4 mm nose radius gives a balanced compromise between strength and surface finish. The moderate nose radius produces a defined part surface while avoiding excessive cutting forces during semi‑finishing passes. The 7° clearance angle maintains a controlled contact geometry at the flank, reducing friction and heat generation. These geometric choices translate into repeatable part tolerances and less downstream rework in serial production.

Effective chip control for stable turning cycles

The insert’s RM4 chipbreaker is optimised for medium to heavy cross‑sections in stainless steels and heat‑resistant alloys, promoting short, controllable chips even under interrupted cuts. Stable chip control minimises tool interference and improves machine uptime, particularly in automated or lights‑out environments. Using this insert with appropriate cutting parameters and coolant strategy enhances process reliability and supports predictable cycle times.

Application guidance and process benefit

This indexable insert suits applications where thermal resistance and edge security are paramount, such as shafts, flanges and components made from rostfreier Stahl or nickel‑base alloys. When paired with the correct holder and cutting data, the grade delivers longer tool life and consistent surface integrity, contributing directly to reduced total machining cost and higher first‑pass yield in production runs.
