A polyaxial bone anchoring device includes a bone anchoring element having a shank and a head, a receiving part having a first end and a second end, a central axis, a first bore, a second bore, and a first support surface between the first bore and the second bore that is substantially perpendicular to the central axis, and an insert piece having a seat for pivotably holding the head, a bounding edge, and a second support surface configured to engage the first support surface to support the insert piece when mounted to the receiving part, the second support surface formed by a projection at an end of the insert piece opposite the bounding edge, wherein the insert piece projects out of the second bore and is rotatable, and is configured to permit the bone anchoring element to pivot at a larger angle at a first location of the bounding edge.
