A finish end mill configured for rotating about a central rotation axis (A R) defining opposite axially forward and rearward directions (D F, D R), and opposite rotational preceding and succeeding directions (D P, D S), the preceding direction (D P) being the cutting direction, the end mill comprising: a shank portion; and a cutting portion extending forward from the shank portion to a cutting end face; the cutting portion comprising: an effective cutting length (L E); a diameter (D E); a plurality of integrally formed teeth; and a plurality of flutes alternating with the plurality of teeth, each flute having a helix angle and a flute depth; each tooth comprising: a rake surface; a relief surface succeeding the rake surface and having a relief surface width measurable in a plane perpendicular to the rotation axis (A R); a cutting edge formed at an intersection of the rake and relief surfaces (28,30); a relief edge spaced apart from the cutting edge and formed at an intersection of the relief surface and a flute surface of the flute succeeding the tooth; and a tooth area (A T) defined between a first radial line (L R1) extending from the cutting edge to the central rotation axis (A R) and a second radial line (L R2) extending from the central rotation axis (A R) to a nadir of the succeeding flute; characterized in that: the plurality of integrally formed teeth are five or more teeth; at an axial location in a front half of the effective cutting length (L E); the teeth have an average radial rake angle value, with one or more teeth having a smallest radial rake angle value, and one or more teeth having a largest radial rake angle value; the cutting portion has an effective cutting length greater than two and a half times the diameter of the end mill; at least some of the teeth with different radial rake angle values have values different from all other non-identical values by 2° or more; and each flute of the plurality of flutes has an increasing depth with increasing distance from the shank. a shank portion; and a cutting portion extending forward from the shank portion to a cutting end face; the cutting portion comprising: an effective cutting length (L E); a diameter (D E); a plurality of integrally formed teeth; and a plurality of flutes alternating with the plurality of teeth, each flute having a helix angle and a flute depth; an effective cutting length (L E); a diameter (D E); a plurality of integrally formed teeth; and a plurality of flutes alternating with the plurality of teeth, each flute having a helix angle and a flute depth; each tooth comprising: a rake surface; a relief surface succeeding the rake surface and having a relief surface width measurable in a plane perpendicular to the rotation axis (A R); a cutting edge formed at an intersection of the rake and relief surfaces (28,30); a relief edge spaced apart from the cutting edge and formed at an intersection of the relief surface and a flute surface of the flute succeeding the tooth; and a tooth area (A T) defined between a first radial line (L R1) extending from the cutting edge to the central rotation axis (A R) and a second radial line (L R2) extending from the central rotation axis (A R) to a nadir of the succeeding flute; characterized in that: the plurality of integrally formed teeth are five or more teeth; at an axial location in a front half of the effective cutting length (L E); a rake surface; a relief surface succeeding the rake surface and having a relief surface width measurable in a plane perpendicular to the rotation axis (A R); a cutting edge formed at an intersection of the rake and relief surfaces (28,30); a relief edge spaced apart from the cutting edge and formed at an intersection of the relief surface and a flute surface of the flute succeeding the tooth; and a tooth area (A T) defined between a first radial line (L R1) extending from the cutting edge to the central rotation axis (A R) and a second radial line (L R2) extending from the central rotation axis (A R) to a nadir of the succeeding flute; the plurality of integrally formed teeth are five or more teeth; at an axial location in a front half of the effective cutting length (L E); the teeth have an average radial rake angle value, with one or more teeth having a smallest radial rake angle value, and one or more teeth having a largest radial rake angle value; the cutting portion has an effective cutting length greater than two and a half times the diameter of the end mill; at least some of the teeth with different radial rake angle values have values different from all other non-identical values by 2° or more; and each flute of the plurality of flutes has an increasing depth with increasing distance from the shank.
