The invention relates to a tool preferably for turning, and an insert therefor. The tool comprises a shank (11) upon which a loop-shaped outer disc (12) is secured. An inner disc (13) is displaceably arranged between the arms of the outer disc (12). A screw (15) is arranged to push the inner disc (13) forwards relative to the outer disc during inward screwing, such that the fore ends of the inner disc force the lower face of the insert against the upper face of the shank (11). The insert (14) is provided with a hole which is arranged to be wedged up on a pin (36) extending in the hole during a forward movement of the insert at the same time as the pin and the hole comprise cooperating surfaces to force the lower face of the insert against the upper face of the shank. |
