SNMG190612-RM5 WSM20S turning insert — Walter Tools (Tiger·tec Silver), RM5 chipbreaker, negative 0°

SNMG190612-RM5 WSM20S is a square indexable insert for turning, optimised for stainless steels and heat‑resistant superalloys with a robust geometry for secure chip control and stable cutting-edge performance

• Tiger·tec Silver coating for heat resistance
• WSM20S grade for stainless and superalloys
• RM5 chipbreaker for predictable chip control
• Square 90° form with 1.2 mm corner radius

Greater productivity through a heat‑resistant grade

The WSM20S grade, realised within the Tiger·tec Silver family, is a coated carbide designed specifically for challenging materials such as rostfreier Stahl (ISO group M) and heat‑resistant superalloys and titanium (ISO group S). The coating supports stable cutting edges and improved heat resistance, which allows machining conditions to be set more aggressively than with conventional grades. Wear mechanisms are controlled by the coating technology, so tool life is extended and process repeatability is increased.

Consistent chip control and surface quality

The combination of the RM5 chipbreaker and the negative 0° rake provides reliable chip formation under heavy cutting loads. The square 90° geometry with a 1.2 mm corner radius reduces vibration and promotes a consistent contact zone, resulting in better surface finish and dimensional stability. These design choices enable predictable performance in interrupted cuts and hardening transitions, while the nominal thickness 06 ensures secure clamping and stable heat distribution.

Practical fitment and application guidance

With a nominal size of 19 mm, tolerance class M and the SNMG190612‑type designation, this indexable insert fits conventional turning toolholders designed for square inserts. The grade is particularly suitable where secure chip evacuation and thermal resistance are required; typical applications include components in the chemical, energy and aerospace sectors. If compatibility with a specific holder or machining scenario is unclear, Metav Werkzeuge offers tailored recommendations and technical clarification based on the machine, material and cutting data.
