A wire-saw constituted by a rope-like core wire and a cylindrical coil-like saw-wire body wounded around the core wire, and a large number of abrasive grains firmly fixed to the saw-wire body by metal. Problems of conventional wire-saws, such as unstable working performance, a short tool life, low safety and low reliability, and so on, are solved.
