Description: T-wheels are used for creating trace lines on a work piece. By scoring a line first with these, a cylinder or inverted cone burr can go in later and expand the mark to a V-groove without dulling it's edge. However I am not a fan of these for detail work as the diamond particles are too large and create chipping upon entry.
