A face grooving tool is disclosed for machining circular grooves in a metal workpiece. More particularly, a face grooving tool includes an elongated shank having an arcuate support blade projecting axially outwardly from one end thereof. The leading surface of the support blade includes an offset V-groove configuration, with the vertex thereof being located nearer to the radially inner surface of the support blade than the radially outer surface. By this arrangement, the radially outermost portion of a cutting insert, which is receivable in the offset groove, is provided with added support during a cutting operation. The arcuate configuration of the support blade enables the blade to be received in the circular groove being machined in the workpiece thereby providing continuous support for the insert.
