Abstract: A quill (10) to be used to superabrasively machine complex shapes, such as airfoil shapes, into a substrate has a shaft portion (12), an enlarged head portion (14) adjacent the shaft portion (12), and a tapered grinding portion (16) adjacent the enlarged head portion (14). The tapered grinding portion (16) has a layer of grit material (24) selected from the group consisting of diamonds and cubic boron nitride thereon. In a preferred embodiment, the quill (10) is a vitrified or plated cubic boron nitride quill on the grinding portion (16). A method of using the tool is also disclosed.
