Abstract: A deep hole drill is rotatable around a geometric axis and includes a body defining a through-channel arranged for internal chip evacuation. The channel opens in front and rear ends of the body. One or more cutting edges are made integrally with the rest of the body, more precisely from a hard material, such as cemented carbide or CERMET. A front bridge of the body extends across the front channel and possesses the integral cutting edge(s).
