The present invention relates to a complex machining end mill capable of processing multiple planes, which can cut a workpiece. The complex machining end mill of the present invention includes: a shank part combined with a milling machine; a side cutting part which machines a side of the workpiece while being formed at a lower part of the shank part; and a bottom cutting part which machines a bottom in contact with the side of the workpiece by an upper part protruding more than the side cutting part while being formed in a diameter larger than a diameter of the side cutting part at a lower part of the side cutting part. Therefore, the complex machining end mill of the present invention can prevent generation of burrs and chippings by being able to machine the side and the bottom of the workpiece at the same time using the side cutting part and the bottom cutting part, and has excellent roughness since the end mill can machine the surface of the workpiece uniformly, and can shorten time required in manufacturing the workpiece. |
