Abstract: A method for bonding together components, such as a tip and a shaft which include mutually facing carbide end surfaces. The tip includes circumferentially spaced flutes formed in its cylindrical outer periphery. The shaft has a cylindrical outer periphery and a plurality of coolant holes extending through the shaft. Bonding of the tip to the shaft is performed by inserting gauge wires into the coolant holes and associated flutes, and positioning brazing material between the first and second end surfaces. A water-soluble bond-blocking material is applied to the gauge wires for preventing brazing of the gauge wires to the brazing material. The brazing material is heated to braze the first and second end surfaces together while the flutes and their associated coolant holes are maintained in alignment by the gauge wires. Then, the gauge wires are removed, and residual bond-blocking material is dissolved in water.

Abstract: A superabrasive tool blank whose carbide side is affixed with a suitable braze alloy, for subsequent shaping into desired tool geometry and induction-brazed forming a cutting tool. The use of the pre-coated braze alloy in the tool blank forming cutting tools allows the direct brazing of the superabrasive blank onto a tool insert, thus minimizing operations and labor time involved for the shaping and handling of the braze substrate in the process of the prior art, i.e., the brazing of the assembly of the superabrasive tool blank, braze alloy, and tool insert. The pre-brazed blank can be conveniently used in automated brazing operations for forming cutting tools.
