WCMT06T308-RM4 WSM20S — Trigon 80° indexable insert for stainless steels & superalloys (Walter Tools)

WCMT06T308-RM4 WSM20S is a coated carbide indexable insert designed for demanding turning and boring tasks in corrosion‑resistant and heat‑resistant alloys

• Tiger·tec Silver coating technology
• WSM20S grade for stainless and superalloys
• Trigon 80° form with 0.8 mm corner radius
• 7° clearance angle and RM4 chipbreaker

High thermal resistance and dependable cutting grade for tough materials

The insert uses the Tiger·tec Silver coating system paired with the WSM20S grade, a coated carbide formulation engineered for materials classified under ISO groups M and S. This combination increases heat resistance and supports stable chip formation, which reduces the risk of build‑up on the cutting edge when turning stainless steels or superalloys. In practice, the coating lowers friction and extends tool life, while the substrate maintains edge stability under elevated temperatures, helping to keep cycle times predictable in production environments.

Geometry that improves chip control and surface quality

A Trigon 80° insert shape with a 0.8 mm corner radius provides a robust cutting edge for interrupted cuts and heavier engagement, while the RM4 chipbreaker has been designed to break and evacuate chips reliably during medium to heavy roughing. The modest 7° clearance angle balances cutting forces and flank contact to minimise rubbing and heat transfer to the workpiece. Together, these geometric features translate into fewer tool changes, more consistent surface finishes and reduced secondary operations for many turning applications.

Integration into process and measurable benefits on the shop floor

As an indexable insert with the designation WCMT06T308‑RM4 WSM20S, the component fits standard toolholders for trigon‑style inserts, enabling rapid index changes and straightforward management of tool stocks. For manufacturers processing corrosion‑resistant alloys or nickel‑based superalloys, the insert delivers repeatable performance, improved process stability and predictable wear patterns. The design supports both roughing and semi‑finishing passes; by reducing edge damage and promoting controlled chip flow, it helps to lower scrap rates and increase overall throughput on mixed‑material production runs.

FAQ

What materials is this insert best suited for?
The WCMT06T308‑RM4 WSM20S is intended for stainless steels (ISO group M) and heat‑resistant superalloys (ISO group S); the Tiger·tec Silver coating and WSM20S substrate are tuned for these groups.

How does the Tiger·tec Silver coating benefit machining?
Tiger·tec Silver reduces friction and improves heat resistance, which helps the WSM20S grade maintain a stable cutting edge and consistent chip formation when machining demanding alloys.

What role does the RM4 chipbreaker play?
The RM4 chipbreaker aids controlled chip segmentation and evacuation during medium to heavy cuts, enhancing process reliability and reducing the likelihood of chip entanglement.

Is the insert suitable for interrupted cuts or heavy engagement?
Yes; the Trigon 80° geometry and 0.8 mm corner radius provide a robust edge that tolerates interrupted cuts and heavier cutting parameters while preserving edge life.

Can the insert be used in standard turning toolholders?
The WCMT format is compatible with holders designed for trigon inserts, allowing quick indexing and simple inventory management in typical turning tool systems.
