An insert includes a body portion and at least one cutting edge disposed on the periphery thereof. The cutting edge includes an inner lip and an outer lip disposed at an angle with respect to one another. A line extending along the inner lip intersects with a line extending along the outer lip at the vertex of the angle. The angular cutting edge further includes a protuberance disposed between, and connecting the inner and outer lips and projecting outwardly away from the body portion beyond the vertex of the angle defined by the intersection of the lines extending from the inner and outer lips. The protuberance having an inner lip connected to the inner lip of the cutting edge and an outer lip connected to the outer lip of the cutting edge to form smooth curvilinear transitions between the lips of the protuberance and the lips of the cutting edge.

A drill includes a tool body having a fluted portion having a second end and a tool head portion, having a cutting tip and at least one cutting edge, removably connected to the second end of the fluted portion. The fluted portion includes a receiving pocket disposed in the second end and is defined by a peripheral side wall extending about the periphery of the receiving pocket. The tool head portion includes a driving projection configured to be inserted into the receiving pocket. The driving projection and receiving pocket have corresponding elongated, curvilinear, dog-bone shapes. The driving projection includes a first end portion, a second end portion, and a central portion disposed between connecting the first end portion and the second end portion. The first end portion and the second end portion each have a width that is substantially greater than a width of the central portion.

In the case of a cutting insert, in particular for counterboring and/or countersinking operations, the cutting insert has two longitudinal sides and two narrow sides between an upper side and an underside. A cutting edge is formed between one longitudinal side and one narrow side and runs obliquely in relation to the underside and extends over at least approximately the entire depth of the cutting body. A cutting face running between the upper side and the underside is provided in the longitudinal side that is facing the cutting edge.
