FIELD: construction.
SUBSTANCE: combined cutter to process a rail foot comprises a casing and a plate from a hard alloy. Plates are installed on the body surface to ensure processing of the lower surface of the rail foot. The body is additionally equipped with two cylindrical collars, arranged at the body ends with plates from a hard alloy, installed at inner sides of collars. The height of collars makes more than height of side surfaces of the rail foot. The inner distance between plates from hard-alloyed collars makes more than the width of the rail foot and heights of rail irregularities in the area of a welding joint. The cutter is made as capable of processing the lower surface of the rail foot and side surfaces of the rail foot by axial displacement of the cutter per two stages.
EFFECT: increased efficiency of cutter operation.
