9. The attachment member of claim 1 , wherein the attachment member is configured to facilitate tool-free attachment of the working portion of the accessory to at least one of the first oscillating power tool and the second oscillating power tool without use of a secondary tool.
10. The attachment member of claim 1 , wherein the plurality of wall portions comprises a plurality of adjacent V-shaped wall portions, each V-shaped wall portion composed of a pair of wall portions that converge at an outer point as they extend radially outward from the central opening and that are joined at an inner point to an adjacent pair of V-shaped wall portions to form the at least a portion of the twelve-point star shape.
11. An attachment member configured to couple a working portion of an accessory to an oscillating power tool comprising:
a planar first bottom surface and a planar first top surface
a planar second bottom surface and a planar second top surface parallel to and spaced from the first top surface;
a central opening defined in at least one of the first top surface and the second top surface;
a keyed sidewall disposed at least partially around the central opening and extending from the first top surface to the second top surface transverse to the first member top surface and to the second member top surface, the keyed sidewall including a plurality of wall portions that together form at least a portion of a twelve point star shape; and
a plurality of equiangularly spaced recesses defined in one of the first top surface and the second top surface, the recesses spaced apart from the keyed sidewall and not in communication with the central opening,
wherein one of the first top surface and the second top surface extends radially inward from the keyed sidewall and the other of the first top surface and the second top surface extends radially outward from the keyed sidewall,
