A concave accessory is versatile for cutting concave-convex profiles. A set of turntables has T-slots for the T-bolts holding the drill bar. These plates are drawn by a gear train. The bar holds roughly yet enough free to rotate. When the tool is constructed, the drill bar is first fastened with the two pivots in the center of the head. Therefore, the toold is a zero radius when the crank is turned. At this time, a pin hole is drilled in each of the rotating plates, as indicated for the pin to touch the punch bar. Then, to adjust the tool, for a desired radius, it is only necessary to place a piece of flat material of the same thickness as the desired radius between the rod and the mounting pins while securing the rod in position.
