Description

Technical Field

[0001] The utility model relates to the technical field of brazing and grinding drill bits, in particular to a replaceable brazing and grinding drill bit. Background Art

[0002] Brazed grinding drill bits are brazed diamond grinding bits that are welded together with diamond particles and a metal matrix by brazing. During the high-temperature brazing process, the metal solder forms a metallurgical bond with the diamond particles, the metal matrix, and the diamond particles, respectively, so that the diamond has an extremely high holding force.

[0003] However, the brazed diamond grinding head is an integrated structure. For example, the Chinese invention patent with publication number CN108161721B discloses a novel multi-layer brazed diamond grinding head, which includes a metal substrate and a diamond layer. A thin-walled cylinder and a frustum are provided on the top of the metal substrate; the diamond layer includes a multi-layer diamond layer and a single-layer diamond layer; the thin-walled cylinder and the frustum are covered with a multi-layer diamond layer. During the use of the brazed diamond grinding head with an integrated structure, if the grinding head is severely worn or damaged, or the clamping handle is damaged, the brazed diamond grinding head needs to be replaced as a whole, and the clamping handle or the grinding head cannot be replaced separately, which will cause a waste of resources.

[0004] To this end, the utility model provides a replaceable brazing and grinding drill bit. Utility Model Content
