A drill bit (1) has a central axis (A) and comprises a tapered cutting end part (2) terminating in a drill tip (3) at one end of the drill bit (1) a shank (4) extending from an opposing end of the drill bit (1) and a body (4a) extending between the cutting end part (2) and the shank (4). A plurality of flutes (5) are formed in the drill bit (1) and helically extend along the body (4a) into the cutting end part (2). Each flute (5) has a flute leading side wall (6) and a flute trailing side wall (7). A land (9) is defined on the body (4a) between each of the flutes (5) and extends to the cutting end part (2). In any body cross sectional plane extending perpendicular to the central axis (A) through the body (4a) a land leading edge region (11) of each land (9) adjoining the flute trailing side wall (7) of a leading adjacent flute (5) is convexly curved.
