ねじフライス用チツプ。[Scope of Claim for Utility Model Registration] A chip provided on a milling body, comprising a plurality of protrusions connected in a straight line at a constant pitch, each having a cutting edge shaped to correspond to the thread groove of a thread to be formed. A multi-thread milling tip used by being attached to a mounting seat, wherein the cutting edge is provided at both ends of the convex strip symmetrically with respect to a center plane in the thickness direction of the tip, and The protruding stripes are formed by being shifted by a certain amount within 1/2 of the peak width of the protruding stripes from the symmetrical position with respect to the center plane in the linear direction, and chip mounting seats are provided at even numbered locations having equal axial positions. The tip is attached to the tip mounting seat of the provided milling cutter body with the front and back sides facing each other alternately, so that the cutting action is performed alternately on the flank side located on the opposite side. Tip for thread milling.
