1. A system for breaking a bond between a concrete form and a concrete product with a rotary power tool, wherein the concrete form holds the concrete product in place during a curing process, wherein the concrete form comprises of at least one portion movable with respect to the concrete product to break the bond between concrete product and the concrete form, the system comprising:
an actuator combined to the concrete form for moving the at least one portion of the concrete form with respect to the concrete product;
a rotary driven power source combined to the actuator for driving the actuator for moving the at least one portion of the concrete form with respect to the concrete product;
a first adapter combinable to the rotary power tool, the first adapter comprising an outer surface, an inner surface, a top surface normal to an axis of rotation connecting the outer surface and the inner surface, two opposing flat faces that are each perpendicular to the axis of rotation and extend axially downward from the top surface and two helical cutouts each beginning at the bottom of a flat face of the two opposing flat faces and extending to the top surface; and
a second adapter combinable to the rotary driven power source.
