Abstract
An end mill for machining titanium includes a cutting portion having blunt teeth alternated with flutes. Each flute includes, in order from the cutting edge, a rake surface, a concavely shaped bending portion, a convexly shaped ejecting portion and a tooth relief edge. The convexly shaped ejecting portion has an ejection height E, which is measurable between an apex of the ejecting portion to an imaginary straight line extending from a nadir of the adjacent bending portion of the flute to the adjacent tooth relief edge. In a plane perpendicular to a rotation axis of the end mill, the ejection height E and a cutting portion diameter D, fulfill the condition 0.010D<E<0.031D.
