Rotary tool and method for manufacturing machined product

A rotary tool, comprising:

• a body extending from a first end toward a second end along a rotation axis and having a cylindrical shape,
• the body comprising:
• a chisel edge located on a side of the first end and intersecting the rotation axis;
• a long cutting edge located on a side of the first end and extending from the chisel edge toward an outer peripheral side;
• a long flank face that is adjacent to the long cutting edge rearward of the rotation axis in a rotation direction and is flat;
• a short cutting edge located on a side of the first end and extending toward an outer peripheral side from a position away from the chisel edge;
• and
• a short flank face adjacent to the short cutting edge rearward of the rotation axis in the rotation direction,
• the short flank face comprising:
• a second flank face that is adjacent to the short cutting edge rearward of the rotation axis in the rotation direction and is flat;
• and
• a third flank face that is adjacent to the second flank face rearward of the rotation axis in the rotation direction and is flat,
• wherein, in front view of the body from the first end, a maximum value of a width of the second flank face in a direction orthogonal to the short cutting edge is smaller than a maximum value of a width of the long flank face in a direction orthogonal to the long cutting edge, and
• a clearance angle of the second flank face is smaller than a clearance angle of the long flank face.
