A drill bit (1) for creating a tubular hole in a bone (9), comprises: a longitudinal body (2) extending along an axis (21) and having a proximal end and a distal end (22)； a main cutting edge (3) formed at the distal end (22) of the body (2)； a main cutting face (4) extending from the main cutting edge (3) and defining a rake angle (α)； and a spiral flute (5) formed around the body (2) and extending from the main cutting face (4) along the axis (21) of the body (2). The main cutting edge (3) is the only single main cutting edge (3) of the drill bit (1). The spiral flute (5) is the only single spiral flute (5) of the drill bit. The rake angle (α) is at least 25°. The drill bit (1) according to the invention drill bit allows for minimizing heat production when drilling a hole into the bone.
