The insert tip for being applied to the rotary cutting tools such as face milling cutter, boring cutter, endmilling cutter etc., has a negative land (5) with a certain width (L) formed a long the main cutting edge (2) and sub cutting edge (3). The land (5) of the main cutting edge is maximized at the corner end (4), which the main/sub cutting edges (2)(3) are crossed, gradually minimized and equalized to the land width of the sub cutting edge. The land (18) has the land angle (K) of 1-45 degrees and the inclined angle (C) of 1-45 degrees starting from the main cutting edge.
