Abstract
A circular cutting device having a stand which rests upon the workpiece with its own weight and via an adhesive layer disposed on the bottom of the stand. A sleeve in the stand threadedly receives a hollow pivot shaft in which a centering pin is axially displaceable against the force of a spring. A radial arm carries the tool and is fixed to a bush rotatably guided on the shaft.
Claims6
A circular cutting device with an arm rotatable about a central axis carrying the cutting tool, wherein the axis is defined by a hollow shaft held in a stand plate which provides the necessary stability for working by means of its own weight and an adhesive coating on its underside resting on the workpiece, the hollow shaft guiding a centering pin displaceably in the axial direction, with a spring tending to hold the centering pin in a position protruding from the stand plate at the bottom.
