Abstract
A rotary tool may include a base extended along a rotation axis from a first end toward a second end. The base may include a cutting part and a flow path located inside the base. The cutting part may include a first flute and a first ridgeline. The first flute may be spirally extended from the first cutting edge. The first ridgeline may be a ridgeline formed by the first flute and an outer peripheral surface adjacent to the first flute on a rear side in a rotation direction. The flow path may include a first sub flow path extended from a main flow path toward a side of the second end. A first angle formed by the rotation axis and the first sub flow path may be smaller than a helix angle formed by the rotation axis and the first ridgeline.
