Abstract: A method for fabricating a rotatable cutting tool is disclosed. The method may comprise fabricating a body of a holder for the cutting tool, wherein the body of the holder extends along an axis and includes a head portion and a shank portion. The head portion may extend from a first end to a second end, and the first end may be configured to receive a cutting tip. The method may further comprise applying a plurality of rotation-assisting strips along an outer surface of the head portion that extend between the first end and the second end. The rotation-assisting strips may project from the outer surface of the head portion. The method may further comprise heat treating the holder having the plurality of rotation-assisting strips.
