Abstract
An end cutting milling tool designed for rotation about a cutting axis and having a cutting end and a base end adapted for engagement by a means for rotation, the tool having cutting blades provided within and located at an outer boundary defined by a surface of rotation about the cutting axis, the boundary having a diameter D2 at the cutting end and a spherical surface at the cutting end having a radius of curvature with an origin on the cutting axis, the radius of curvature having a magnitude, R1, that is greater than D2/2 and is less than 50 times D2, the boundary having a flank portion extending from the cutting end toward the base end.
