More Information
Summary:A holder for an abrasive disc allows for a quick manual change of the abrasive disc. The holder including an uncoupling mechanism that in turn includes a handle comprising a pin and an adjacent hub comprising a partial annular channel. The handle and hub have a limited rotational engagement wherein the pin travels in the channel. When an operator desires to replace an abrasive disc, the operator grasps the handle with one hand and rotates the disc, face plate, and hub, together as a unit, with the other hand. This counter-rotation breaks the tight attachment of the disc on the shaft of the finishing tool, so that disc can be easily unthreaded from the shaft.
