Abstract: A tool for deburring holes is proposed, comprising a basic body, which rotates about a rotation axis of the tool and has a clamping shank, and at least one lip holder elastically movable relative to the basic body, the lip holder comprising at least one cutting element which projects radially with respect to the rotation axis and has at least one lip leading edge oriented at least partly transversely to the cutting direction, which tool exhibits improved deburring and greater endurance compared with the prior art. This is achieved by the cutting element (8, 30, 31) being made of carbide.
