A tool for chip removing machining, including a long narrow basic body having an envelope surface which is concentric with a center axis, and two opposite ends, and a replaceable loose top which is connected to the basic body via a first coupling that includes a first seating formed in one end of the basic body and a first male element formed in one end of the loose top. The basic body includes a primary part body made of a first material having a first modulus of elasticity, and a secondary part body which includes the first seating and is made of a second material having a second modulus of elasticity which is lower than the first modulus of elasticity. The two part bodies of the basic body are interconnected via a second coupling which includes a second seating in the secondary part body as well as a second male element that is formed on the primary part body and has one or more precision machined flank surfaces that are arranged to apply, together with one or more co-operating and precision machined flank surfaces of the second seating, joining axial forces to the part bodies by turning the part bodies in relation to each other.
