Abstract
Abstract An improved cutoff or grooving tool of the cartridge type is disclosed, including a cartridge assembly which comprises a support member, a clamping member, and a cutting insert, all of which are receivable in one or more pockets opening into the front and top faces of an elongate tool-holder body. The support member is mounted in the pocket in such a way that it is drawn down and into the pocket to provide the maximum rigidity to the forces encountered in the operation of the instrument. The assembly is releasably received in the pocket so that the entire assembly can be readily and quickly removed for replacement due to damage, change of size of cut, etc., without the necessity of providing special tooling in most instances.
