摘要： Thermally stable abrasive compacts of hexagonal shape have been found to have excellent abrasive properties in the abrading of a medium to soft rock having an unconfined compressive strength of less than 240 MPa. Preferably the abrasive tool used is a surface set drill bit wherein some of the thermally stable abrasive compacts are so located around the working edge of the bit that a side thereof acts as a gauge stone for the working portion.

摘要： 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.

摘要： A tool insert comprising a composite diamond abrasive compact and a method of its production are provided. The composite abrasive compact is characterized by an intermediate layer between the diamond compact and the cemented carbide support. The intermediate layer consists essentially of discrete cubic boron nitride particles constituting 60 to 40 percent by volume of the intermediate layer, carbide particles, preferably tungsten carbide particles and diamond solvent, preferably cobalt. The carbide particles and diamond solvent together constitute 40 to 60 percent by volume of the intermediate layer and the diamond solvent constitutes 15 to 25 percent by volume of the carbide/solvent combination.
