A rotary cutting tool with a longitudinal axis, comprising: a shank portion; a cutting portion extending from the shank portion to a cutting tip, the cutting portion having a length of cut, and a plurality of blades separated by spaced flutes extending along the length of cut, each of the blades including a leading face, a trailing face, a land surface extending between the leading face and the trailing face, and a cutting edge at the intersection between the leading face and the land surface; and a plurality of chip-breaking features disposed in the land surface of each blade in a chip breaker pattern that extends along the length of cut, the chip-breaking features of each of the plurality of blades being equidistant from each other, wherein the chip breaker pattern begins at a first distance from the cutting tip for a first blade of the plurality of blades, the chip breaker pattern repeating at the first distance for each alternating blade of the plurality of blades, wherein the chip breaker pattern begins at a second, different distance from the cutting tip for a second blade of the plurality of blades, the second blade immediately adjacent the first blade, the chip breaker pattern repeating at the second distance for each alternating blade of the plurality of blades, wherein the chip breaker pattern is such that the chip-breaking features disposed in the land surface of one blade are located between the chip-breaking features disposed in the land surface of immediately adjacent blades, characterized in that each chip-breaking feature is formed by a small radius, a large radius and a joining radius therebetween, the small radius being closer to the cutting tip than the large radius, and a depth of each flute varies along the longitudinal axis from the cutting tip toward the shank portion, the depth of each flute being greater proximate the cutting tip. a shank portion; a cutting portion extending from the shank portion to a cutting tip, the cutting portion having a length of cut, and a plurality of blades separated by spaced flutes extending along the length of cut, each of the blades including a leading face, a trailing face, a land surface extending between the leading face and the trailing face, and a cutting edge at the intersection between the leading face and the land surface; and a plurality of chip-breaking features disposed in the land surface of each blade in a chip breaker pattern that extends along the length of cut, the chip-breaking features of each of the plurality of blades being equidistant from each other, wherein the chip breaker pattern begins at a first distance from the cutting tip for a first blade of the plurality of blades, the chip breaker pattern repeating at the first distance for each alternating blade of the plurality of blades, wherein the chip breaker pattern begins at a second, different distance from the cutting tip for a second blade of the plurality of blades, the second blade immediately adjacent the first blade, the chip breaker pattern repeating at the second distance for each alternating blade of the plurality of blades, wherein the chip breaker pattern is such that the chip-breaking features disposed in the land surface of one blade are located between the chip-breaking features disposed in the land surface of immediately adjacent blades, characterized in that each chip-breaking feature is formed by a small radius, a large radius and a joining radius therebetween, the small radius being closer to the cutting tip than the large radius, and a depth of each flute varies along the longitudinal axis from the cutting tip toward the shank portion, the depth of each flute being greater proximate the cutting tip.
