Abstract
A tool component is provided which comprises an abrasive compact bonded to a cemented carbide support body. The abrasive compact has two zones which are joined by an interlocking, common boundary. The one zone provides the cutting edge or point for the tool component while the other zone is bonded to the cemented carbide support body. In use, the tool component is so located in the working surface of the tool that the lower zone is partially embedded in that surface. The interlocking, common boundary is located above the working surface.
