PURPOSE: A polygonal turks-head of a rolling mill is provided in which rolling roll installed roll holders are removably arranged in a polygon shape on a frame so that parts are compatibly used, and the roll holders are easily attached to or detached from the frame. CONSTITUTION: In a polygonal turks-head of a rolling mill comprising a frame which is uprightly installed on a rolling stand, and on the central part of which an opened part is formed so that a wire rod penetrates into thus passes through the opened part; a plurality of roll holders which are arranged on the frame, and at which rolling rolls for rolling the wire rod are installed respectively; and a locking means for arranging the roll holders on the front surface part of the frame with spaced apart from each other in a certain distance so that a polygonal space is formed among the rolling rolls, the polygonal turks-head of the rolling mill is characterized in that the locking means comprises a plurality of tap holes(42a to 42d) machined on the front surface of the frame so that a plurality of mounting bolts penetrating the roll holders and the front end of the mounting bolts are coupled to the plurality of tap holes(42a to 42d), wherein the tap holes(42a to 42d) are machined in a distance of 60, 90 and 72 degrees of an angle so that the roll holders are arranged in a triangle, rectangle, pentagon or hexagon shape.
