<p>The present invention relates to a blade for a milling cutter including a rotary unit which is installed in a machine tool and is rotated, and a body unit which is installed on the rotary unit and in which a plurality of installation grooves are formed along an outer circumferential face and one face for forming the installation grooves are provided as an inclination face, the blade comprises: a main body unit which is installed in the installation groove and in which a face coming in contact with one face of the body unit for forming the installation grooves is provided as an inclination face to prevent the blade from being separated from the installation groove when the rotary unit rotates; and a tip unit which is installed in the main body unit and includes a tip unit for forming a tip end, wherein the milling cutter includes a support unit which supports the main body unit such that the blade comes in close contact with one face of the body unit for forming the installation grooves and the other face of the body unit facing one face of the body unit, and the main body unit includes a first face unit which is provided as an inclination face and comes in contact with one face of the body unit for forming the installation grooves, a second face unit which is provided as an inclination face and comes in contact with the other face of the body unit facing one face of the body unit, and a third face unit which comes in contact with the support unit. Accordingly, it is possible to effectively prevent the blade of the present invention from being separated from the installation groove by centrifugal force when the rotary unit rotates. Therefore, a workpiece is prevented from being broken and safety of a worker is secured.</p> |
