摘要： An object is to provide a cutting insert for a milling cutter with which efficiency in machining can be increased. The cutting insert includes two polygonal main surfaces facing each other and side surfaces each connected to a corresponding side of each of the main surfaces. The side surfaces include a major side surface through which an attachment hole extends, a first minor side surface perpendicular to the major side surface, and a second minor side surface disposed between the first minor side surface and the major side surface. A ridge between each of the main surfaces and the major side surface forms a major cutting edge, and a ridge between each of the main surfaces and the second minor side surface forms a minor cutting edge. An angle between the major cutting edge and the minor cutting edge is 145° or larger.

摘要： Forming cutting inserts for milling cutters that meet both the demands of providing good sharpness and cutting edge tip strength and the demand of increasing the number of corners used according to use is a matter to be achieved. A cutting insert, used for a milling cutter, which includes two polygonal main surfaces that are opposite each other and a plurality of side faces and whose main surfaces are rake faces, whose side faces are flank faces, and whose ridge lines at positions where the main surfaces and the side faces cross each other are used as cutting edges include two major side surfaces that are opposite each other and a plurality of minor side surfaces that are formed continuously with the major side surfaces. A mounting hole is provided at the two major side surfaces in a direction in which the mounting hole extends therethrough, and areas of the two major side surfaces are greater than those of the main surfaces. The major side surfaces and the minor side surfaces are provided with flutes along entire regions of the cutting edges.
