Abstract

Abstract A flaring tool including a die adapted to engage the end of a sleeve and an element adapted to grip the shank of a fastener extending through the sleeve, with a tension force being applied to the shank and an inward force being applied to the die through the actuation of a lever. The gripping element is slidable in a body, with the lever being pivotally mounted on one side of the body. A spacer may be provided to render the die inoperative so that the tool may be used to force an interfering part into an opening in the workpiece without simultaneously bending the flange. Such a part may be a nut with a knurled exterior that becomes embedded in the workpiece to prevent the nut from rotating. A member may be substituted for the die to exert a pull on a fastener attached to the workpiece for accomplishing removal of the fastener.
