Cutting insert and drilling tool

A drilling tool comprising:

• an elongated tool body extending along a drill axis, wherein the tool body includes at least two chip flutes and one axial end portion provided with a peripherally arranged first insert seat and a centrally arranged second insert seat;
• and
• a cutting insert arranged in the first insert seat, the cutting insert comprising an insert body having a central longitudinal axis extending along a longitudinal direction of the insert body and an imaginary centre plane-including the central longitudinal axis, the insert body having a pointed shape substantially in the longitudinal direction, and being defined by a top surface, a bottom surface, and a circumferential surface extending between the top surface and the bottom surface, wherein the insert body at the top surface includes a first rake face and the bottom surface includes a second rake face, the insert body at the circumferential surface including a first radial side and a second radial side extending in the longitudinal direction on opposite sides of the insert body, the first radial side and the second radial side being parallel and each extending between the top and bottom surfaces and perpendicular to the centre plane, and a first axial side and a second axial side extending across the longitudinal direction on opposite sides of the insert body, and wherein the insert body includes a first cutting edge extending along a rim portion at an intersection between the first rake face and the first axial side, and a second cutting edge extending along a rim portion at an intersection between the second rake face and the first axial side, wherein the first cutting edge includes a first edge portion and a second edge portion extending at an obtuse angle to each other, and the second cutting edge includes a third edge portion and a fourth edge portion extending at an obtuse angle to each other, the first, second, third, and fourth edge portions forming said pointed shape, the first axial side including a first relief face and a second relief face, the first relief face extending along the first rake face on one side of the imaginary centre plane and the second relief face extending along the second rake face on an opposite side of the imaginary centre plane, wherein the first relief face forms an obtuse angle with the centre plane, such that the insert body is longer in the longitudinal direction at the first cutting edge than adjacent to the centre plane, and wherein the second relief face forms an obtuse angle with the centre plane, such that the insert body is longer in the longitudinal direction at the second cutting edge than adjacent to the centre plane, and wherein as seen in a view perpendicular to the imaginary centre plane, a first corner portion disposed between the first and second edge portions is arranged on one side of the central longitudinal axis and a second corner portion disposed between the third and fourth edge portions is arranged on an opposite side of the central longitudinal axis.
