ABSTRACT:
A double-pivot circle-cutter including a pivot member pivotally mounted on a support arm and having a sliding beam slidably extending therethrough. The pivot member is vertically adjustable, and its axis of pivot extends through the support arm. The sliding beam carries a platform which in turn pivotally supports a holder for a cutting member adjacent one end of the platform. The axes of pivot of the pivot member and of the cutting-member holder are parallel, and the latter shifts with the sliding beam to make the distance between the axes equal to the radius of the desired circular cut.
