A sawing thread consists of an abrasive mixture containing a binding resin and an abrasive material, and a multi-filament thread composed of tear resistant fibres. The fibres are arranged in parallel and are surrounded by the abrasive mixture. The space between the fibres is filled with the mixture. The fibres consist of m-aramide, p-aramide or ultra strong polyethylene. <??>A sawing thread consists of an abrasive mixture containing a binding resin and an abrasive material, and a multi-filament thread composed of tear resistant fibres.
