摘要： A solid end mill is provided which can prolong the useful life of the tool, without any adhesion to the work material, even aluminum or similar material, during a or cutting or drilling operation. The solid end mill includes a chip discharge flute, which is formed in the outer periphery of a nearly cylindrical tool main body. The nearly cylindrical tool main body rotates around a central longitudinal axis. A cutting edge is formed at a ridge portion on the outer periphery of the tool main body. The cutting edge is adjacent to a wall surface constituting a rake face of the chip discharge flute. The rake face faces in the tool rotational direction. A convex portion may be formed so as to be adjacent to and raised from a concavely curved portion. The concavely curved portion stretches to the cutting edge and is formed between the flute bottom of the chip discharge flute and the cutting edge.
