Title: Brazed diamond dressing tool

Abstract: A dressing blade for finishing and reconditioning new and used abrasive grinding and cutting tools has a slab-shaped shank with an extension protruding longitudinally from the shank. Superabrasive grains are disposed on the surface of the extension and held in place by a brazed metal composition. This composition is formed by brazing a powdered mixture of brazing metal components and active metal components. Specific extension configurations are provided which allow aligning the superabrasive grains in single layer arrangement for precise dressing and simple fabrication of the tool. The novel dressing tool exhibits excellent wear characteristics.
