Abstract
A hand tool for holding a spinning disc while the circumference of the disc is being ground is noteworthy for its ability to accommodate disks of various thicknesses. The disc is gripped between two resilient grippers that rotate with the disc. The grippers are mounted for rotation to the jaws of the tool. The jaws slide open and closed on two spaced parallel guide pins that are parallel to the axes of rotation of the grippers. This assures that as the jaws are opened or closed to accommodate discs of different thicknesses, the axes of the grippers remain colinear.
