A cutting insert a rotary cutting tool using the same. The cutting insert is a substantially prismoidal body having top, base and side surfaces and cutting edges formed at intersections of the top and side surfaces. The insert, when mounted in the tool, has at least one inoperative side surface which has at least one depression formed symmetrically with respect to a center of the side surface length. An upper portion of the depression is disposed substantially in the vicinity of the top surface. The depression has a bottom wall oriented substantially co-directionally with the side surface and a pair of side walls oriented substantially transversely to the side surface. The depression is designed so that, when the insert is mounted in the tool, at least one wall of the depression constitutes a support of the cutting insert in the direction along an axis of rotation of the tool.
