The cutting edge profile of the rotary cutting tool has a lower radius portion and a middle convex portion. The lower radius portion has its center on the axis of the rotary cutting tool and the middle convex portion is defined by an inverse square curve of form Y=1/X2 with the vertical axis of the origin of the inverse square curve offset from the axis of the rotary cutting tool. X has values between 0.25 units and 4 units.
