FIELD: process engineering.
SUBSTANCE: invention relates to metal cutting. Cutting is performed by motor-drive disc saw, drive motor being mounted at the cutter body casing. Cutter comprises structure designed to prevent saw disc safety element fastener fallout, said fastener intended for locking the saw disc element relative to cutter body casing. Saw disc mount portion locating said saw relative to spindle is designed to output motor drive power and is protected by safety element.
