Evoloop® WKE 42
Evoloop® WKE 42 is a proprietary tungsten high speed steel containing 10 percent cobalt. Evoloop® WKE 42 is harder than most high-speed steels and has in addition a reasonably good toughness. Evoloop® WKE 42 is used mainly for tools requiring maximum abrasion resistance and medium toughness.
