Abstract
A method for manufacturing a continuous drill ring for a core drill bit is disclosed. The method includes forming at least two green compacts in layers in a direction of formation between a bottom side and a top side by successively applying powder layers containing a powder mixture and diamond layers containing diamond particles that are arranged in a set pattern, shaping the green compacts into ring segments under the effect of pressure, sintering the ring segments under the effect of heat, and combining the sintered ring segments in a circular manner and joining the same in a frictionally engaging or integrally bonding manner at the lateral edges thereof so as to obtain the continuous drill.
