ABSTRACT:
In a rotary cutting tool for use with at least one cutting tip, a cutter body has its forward end whose outer periphery has mounted thereto the cutting tip. A chip suction device is arranged outwardly of an outer peripheral surface of the cutter body for drawing chips generated by the cutting tip. The chip suction device includes a generally cylindrical cover unit having a wall for covering the cutter body. The cover unit is supported by the cutter body for rotation relative thereto. A chip accommodating chamber is defined between an inner peripheral surface of the cover unit and the outer peripheral surface of the cutter body. A suction port unit is provided in the wall of the cover unit and communicates with the chip accommodating chamber. A chip guide unit is arranged at the forward end of the cutter body in facing relation to the face of the cutting tip for guiding the chips generated by the cutting tip to the chip accommodating chamber.
