WSM20 carbide insert grade

Description

1. Product Overview

The WSM20 carbide insert grade is a premium tungsten carbide-based cutting tool material engineered for high-performance metal turning operations. It is primarily used for machining alloy steels, stainless steels, and general steels in industrial manufacturing environments. The key value proposition lies in its tough fine-grain carbide substrate combined with a multi-layer TiAlN+Al₂O₃+(ZrN) coating, delivering exceptional tool life, edge stability, and consistent cutting performance. Strategically important in the global market, WSM20 enables manufacturers to achieve superior efficiency in finishing, roughing, and grooving operations while reducing downtime and tooling costs.
