The invention aims at providing a forced-scrap-cutting internal-cooled drill with long service life, so as to reduce the use cost of customers. The forced-scrap-cutting internal-cooled drill provided by the invention comprises a handle part and a cutter edge part, wherein a water inlet passage is formed in the handle part in a penetrating manner, and parabolic scrap discharging grooves and side cutter edges are formed on the cutter edge part along the axial direction. The forced-scrap-cutting internal-cooled drill is characterized in that a concave arc-shaped scrap cutting groove is formed in one face, facing the rotating direction of the internal-cooled drill, of each side cutter edge. During work, the arc-shaped scrap cutting grooves carry out secondary cutting on scrap strips, and scraps generated can be automatically cut, so that the scraps are discharged from the scrap discharging grooves very easily and cannot be accumulated in the scrap discharging grooves and cannot cause severe nose wear and cutter break-up.
