Abstract

Stamping, drawing and spinning cores or dies for cold working are formed of a number of concentric tungsten carbide elements fitting into a slightly conical i.e. =4 degrees housing in the pref. tool steel body of the tool. The invention considerably increases the shock resistance of the core.
