Abstract
Abstract A cable saw in which the cutting members are abrasive bodies bonded to short sections of tubes. The ends of the tubes are swaged over spherical bodies attached to the cable so that the cable may float within the tubular cutting members during operation. The spaces between cutting members are bridged by flexible sleeves which protect the cable from loose abrasive particles.
