A drill bit (10) comprises an apical end (1), a coronal end (2), a longitudinal axis (L) extending between the apical end and the coronal end, a drill bit core (11), and a cutting portion (C) extending at least partially along the drill bit core. Along the cutting portion an outline of a cross-section of the drill bit core perpendicular to the longitudinal axis comprises at least one outermost point (12) at a first radial distance (r1) from the longitudinal axis and at least one cutting point (14) at a second radial distance (r2) from the longitudinal axis. Along a first part of the cutting portion, the second radial distance is smaller than the first radial distance, and along a second part of the cutting portion, the second radial distance is substantially equal to the first radial distance.
