Drill

A drill comprising a body having a front end and a back end opposite to the front end, wherein

• the body includes a first cutting edge, a second cutting edge apart from the first cutting edge to the back end relative to the first cutting edge, an outer peripheral portion, and a flank face,
• the outer peripheral portion being provided with
• a helical flute extending along a center axis of the body, and
• a recess extending in a direction crossing the center axis and traversing the outer peripheral portion, the center axis of the body extending from the front end to the back end,
• the recess includes
• a first surface continuous to the outer peripheral portion and extending from the outer peripheral portion toward the center axis, and
• a second surface continuous to the first surface and extending from the first surface toward the front end of the body,
• the first cutting edge is constituted of a first ridgeline formed by the flank face and a surface of the helical flute,
• the second cutting edge is constituted of a second ridgeline formed by the first surface and the surface of the helical flute,
• in a side view of the body in a first direction in which a distance between the center axis of the body and a first outer end of the first cutting edge is seen the longest, a second outer end of the second cutting edge is located closer to the center axis relative to the first outer end of the first cutting edge, and
• in the side view of the body in the first direction, the recess is inclined with respect to the center axis and crosses the center axis.
