Abstract
A spirally-fed drilling and milling cutter to be driven spirally in order to drill and mill includes a shank, a groove at one of a plurality of offset positions at one end of the shank, a blade at a bottom side of the groove, and a spiral flute on the periphery of the main body of the shank, wherein the spiral flute has a flute end connected with the groove. When the cutter is rotated at high speed and in high torsion, drilling/milling chips are pushed upward, along with a cutting liquid, through the spiral flute out of a hole being made. Thus, the heat generated by the cutting action is reduced, and the chips are efficiently discharged, allowing the cutting edges to stay sharp and the cutter to make deep holes.
