Abstract
A cutting tool comprising a supporting base and an outside and an inside abrasive grain layer projecting concentrically from the supporting base in a radially spaced relationship, and a method for its production. The outside and inside abrasive grain layers are formed by electrodepositing abrasive grains on the supporting base and then dissolving part of the supporting base. The inner circumferential surface of the projecting portion of the outside abrasive grain layer and the outer circumferential surface of the projecting portion of the inside abrasive grain layer are smooth surfaces.
