Abstract
Abstract The invention comprises a cut off and grooving tool of substantially simplified construction which provides increased versatility and rigidity in using disposable cutting inserts. A vertical slot and key attachment means between tool body and insert locating member provides a more rigid tool and more accuracy in locating the cutting edge. The simplified construction allows a single tool body or shank to accommodate a variety of different insert widths in several different cutting positions.
