Drill and method for manufacturing machined product

A drill, comprising:

• a base extended along a rotation axis from a first end to a second end and being rotatable around the rotation axis, and being configured to perform a cutting process when rotated in a rotation direction around the rotation axis, the base comprising:
• a first part including the first end and having a first outer diameter,
• wherein the first part includes a first cutting edge extending from the first end,
• a first flute that leads the first cutting edge relative to the rotation direction,
• a second flute that follows the first cutting edge relative to the rotation direction,
• a second part which is between the first cutting edge and the second end, and has a second outer diameter that is larger than the first outer diameter,
• a step which is located between the first cutting edge and the second part and has a larger outer diameter as coming closer to the second part,
• wherein:
• a length of each of the first part and the second part is longer than a length of the step,
• the step comprises:
• a first step that is a non-cutting step, and
• a second step that includes a second cutting edge such that the second step is a cutting step,
• each of the first and second steps is located where the first outer diameter increases to the second outer diameter,
• the second step is between the first cutting edge and the first step,
• the second flute is between the first step and the second step relative to the rotation direction,
• the first step leads second flute relative to the rotation direction, and
• the second step follows the second flute relative to the rotation direction.
