TOOL COMPONENT |
摘要 |
A tool component comprises abrasive compact, typically a diamond abrasive compact, having a flat working surface which presents a cutting edge and an opposite surface bonded to a surface of a cemented carbide substrate to define an interface having at least two steps. The steps extend from one surface of the component to another surface and the interface is spaced from the working surface at one of the component surfaces a greater distance than at the other component surface. The tool component has particular application as a cutting insert for a rotatable cutter of an earth boring bit.
