Abstract:
A cutting pick comprising an elongate shank and a cutting tip which is mounted to one end of the shank to project from that end. At least two sleeve segments are provided and those segments are circumferentially fixed about the shank to form a substantially annular sleeve. The sleeve can be fixed about the shank in non-contacting relationship with the trailing end of the cutting tip. Moreover, the cutting tip can have a portion of maximum diameter which is of greater diameter than the inner diameter of the sleeve so that the portion of maximum diameter overlies the sleeve radially.
