Abstract
An end mill includes end cutting edges located at a front end side of a cutting edge portion of a body including rotation axis, peripheral cutting edges, and helically extending flutes. Each of the peripheral cutting edges and the flutes are alternately located from the front end side to a rear end side, and a first distance between a deepest position of the flute and the rotation axis is equal among the respective flutes in a cross section taken along the rotation axis. The flute includes a first region located at a side of the peripheral cutting edge and includes the deepest position, a second region located at a side of a heel, and a boundary. A second distance from the rotation axis to the boundary located at the rear end side is larger than the second distance located at the front end side.
