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).

Abstract: A device for chip forming machining including first and second rotatable bodies arranged along a common axis of rotation. The first body forms a male element, and the second body forms a female element into which the male element is threaded for forming a threaded joint. The male element has an outer circumferential area displaced in the axial direction in relation to the thread thereof and which engages a corresponding inner circumferential area of the female element by a press-fit. One or both of those circumferential areas has an out-of-roundness, such that there occurs a press-fit along two or more preselected regions in the circumferential direction.
