Abstract
A composite cast tool is cast in one continuous piece, partly of steel and partly of grey iron, so that an interconnection zone is formed between the steel and the grey iron. The steel portion forms the working component of the tool, for example a cutting edge, and the grey iron portion forms the body component of the tool. The steel portion and the grey iron portion have projections or walls extending towards one another. The interconnection zone is located in the region of union between these walls and is planar.
