The present disclosure relates to a brazed superabrasive assemblies and method of producing brazed superabrasive assemblies. The brazed superabrasive assemblies may include a plurality of braze alloy layers that are positioned opposite a stress relieving layer. The stress relieving layer may have a solidus temperature that is greater than a solidus temperature of the plurality of braze alloy layers.

A tool and a method of making the tool are disclosed. The tool includes a superabrasive compact, for example, a volume of silicon carbide diamond bonded composite, directly bonded to a tungsten carbide body during sintering. The green body may have a recess with a complementary shape to the superabrasive compact, whereby after inserting at least a part of the superabrasive compact within the recess and sintering, the tungsten carbide body and the recess shrink to form an interference fit therebetween.

A method of making a near-net superhard material body includes preparing granules from a mixture of superhard powder, binders, and fluids, compacting the granules to form a soft green complex-shaped body, heating the soft green body in a furnace to form a hard green body free from residual binders, embedding one or more of the hard green bodies in a containment powder or a containment means and forming a pressure cell, sintering the cell at high pressure and high temperature, and removing the containment powder from the cell or removing the inserts from the containment means to reveal one or more near-net bodies.

Near-net cutting tool insert

An abrasive tool insert is formed from a substrate having an inner face that has a center. The inner face slopes outwardly and downwardly from the center. An annular face slopes downwardly and outwardly from the inner face. An abrasive layer, having a center and a periphery forming a cutting edge, is integrally formed on the substrate.

Cutting tools with two-slope profile

An abrasive tool insert is formed from a substrate having an inner face that has a center, and annular face which annular face has a periphery. The inner face slopes outwardly and downwardly from the center at an angle ranging from between about 5&#xb0; and 30&#xb0; from the horizontal. The annular face surrounds by the inner face and terminates at the periphery. The annular face slopes downwardly and outwardly from the inner face at an angle of between about 20&#xb0; and 75&#xb0; from the horizontal. A continuous abrasive layer, having a center and a periphery forming a cutting edge, is integrally formed on the substrate and defines an interface therebetween.
