摘要： A wedge anchor setting tool has a drill bit component having a drill tool receiving member and a drill bit member. A polygonal shaped element is located between the two members. A sheath component has an open passage and an opening at the terminus of each end. The first end has a polygonal shape which conforms to the polygonal element and the second end having a polygonal shape which conforms to the shape of the wedge anchor. The method of installation using the tool includes drilling a channel into a wall using the drill bit component. The sheath component is then inserted over the drill bit component and a wedge anchor is inserted into the smaller opening at the second end of the sheath component. The wedge anchor is then drilled into the wall and tightened by the drilling tool to secure an attachment member to the wall.

摘要： A method of joining a component, such as a cutting element, to another component or body of an earth-boring tool, according to embodiments of the present disclosure, includes disposing a third-body structure, which may comprise a braze material, between a surface of the component and a surface of the another component of the earth-boring tool. The component to be joined is then rotated relative to the surface of the another component to generate frictional heat in the third-body structure and to at least plasticize material of the third-body structure. After the rotation, the plasticized material of the third-body structure is compressed between the surfaces and then allowed to solidify, which bonds the component to the another component without deforming either the component or the another component.
