Drill bit

A drill in which a chip groove (7) is formed in the tip outer periphery of a drill body (1) that rotates about an axis (O) in a drill rotation direction (T), and a cutting edge (5) is formed in an intersection ridge section between a tip flank surface (6) and a wall surface of the chip groove (7) that faces the drill rotation direction (T). The cutting edge (5) is provided with a main cutting edge section (5B) extending from the inner peripheral side to the outer peripheral side of the drill body (1), and a cutting edge shoulder section (5C) extending from the outer peripheral end (P) of the main cutting edge section (5B) to the outer periphery of the drill body (1), and is honed such that the actual rake angle increases on the negative angle side at the outer peripheral end (Q) of the cutting edge shoulder section (5C) with respect to the outer peripheral end (P) of the main cutting edge section (5B), and the actual rake angle increases on the negative angle side at the outer peripheral end (Q) of the cuttin
