Abstract: A method of making a tool having a joining a maraging steel joining partner and a cemented carbide joining partner by brazing and a tool made according to the method is provided. The method includes depositing a Ni coating onto the maraging steel joining partner prior to applying the filler material having at least 70 wt % Cu. The braze joint shows excellent shear strength.

Abstract: The present invention relates to a cutting tool insert including a carrier body made of maraging steel. The carrier body has at least one rake face, at least one flank face and at least one pocket, wherein the at least one cutting element is situated in the at least one pocket. The cutting element has at least one cutting edge and can be made of any material known in the art of cutting. The cutting tool insert further includes a braze joint joining the carrier body and the at least one cutting element, wherein the braze joint includes Ti and a Ti containing joining layer with a thickness of between 0.03 and 5 ?m adjoining to the cutting element.

Abstract: A tool includes a cemented carbide part and a maraging steel part, wherein the two parts are joined by brazing. The cemented carbide part has a hard phase embedded in a metallic binder phase matrix. The maraging steel part has a hardness of between 350 and 600 HV1 with a standard deviation between 0 and 20 HV1. A method of making such tool is also provided.

Abstract: A tool includes a superhard part of a polycrystalline diamond (PCD) or a cubic boron nitride (cBN) sintered compact bonded to a cemented carbide substrate and a maraging steel part, where the cemented carbide substrate and the maraging steel part parts are joined by brazing. The present also relates to the making of such tool. The tool provides a strong braze joint and a steel part that have an even hardness.
