the main edge (3) and an edge -- it is related with the fraise which can cut parallel and the smooth and even work surface to axis of rotation (7) of a fraise (1) including an end (4) and a front edge (6). The bus-bar (8) of the enveloping surface (9) which produces each main edge during rotation of a fraise -- an edge -- it has the 1st line segment (11) that shows the projection length (17) of at least 1 mm within the projection to axis of rotation following the zone (10) equivalent to an end. The distance of the 1st line segment and axis of rotation increases from the minimum in the 始端 to the maximum in a termination. The tangent of each point of the 1st line segment accomplishes the parallel lines to axis of rotation, and the angle of 0*5 degrees. The 1st line segment shifts to the 2nd line segment (12) with the projection length (18) of at least 1.5 mm. The distance of the 2nd line segment and axis of rotation decreases from the maximum in the 始端 to the minimum in a termination. The tangent of each point of the 2nd line segment accomplishes the angle (alpha 2) of more than 0 degree and 3 degrees or less respectively with the parallel lines to axis of rotation. The projection length of the 2nd line segment has one at least 1.5 times the length of that of the 1st line segment.
