The Dremel multi-vise helps you secure your project or free up a hand for extra control when using your Dremel rotary tool. The removable cushioned jaws on the 2500-01 help protect delicate workpieces while providing a firm, steady grip, and they clamp to any worksurface up to 2-1/2 inches thick. This holder turns your Dremel rotary tool into a stationary sander, grinder or polisher, and the removable jaws create a stand-alone bar clamp on the Dremel 2500-01.
