Abstract

A mechanical-activated inner diameter (ID) grooving tool includes a shank, a body, a stopper, an insert cartridge, a bushing and an end cap. The shank includes a tapered piston having an extension surface and a retraction surface. The insert cartridge includes a tapered piston pocket having a piston-engaging face and a piston-retracting face. Axial movement of the tapered piston in a first direction causes the extension surface of the tapered piston into contact with the piston-engaging face of the insert cartridge, thereby causing the insert cartridge to move in a radially outward direction. Axial movement of the tapered piston in a second, opposite direction causes the retraction surface of the tapered piston into contact with the piston-retracting face of the insert cartridge, thereby causing the insert cartridge to move in a radially inward direction.
