ABSTRACT:
An arbor for a rotary cutting tool which includes an elongated cylindrical shank that has an axial bore formed therethrough. The upper end of the shank is adapted to be attached to the drive spindle of an electric motor. The arbor shaft is slidably mounted in a carrier sleeve which is rotatable with the arbor shank which is retained against axial movement by a mounting means. An annular cutter is attached to the lower end of the arbor shank and a pilot ejector member is slidably mounted therein. The pilot ejector member is retained in the normal at rest position by a spring which has its upper end mounted in a bore in a piston that is attached to the carrier sleeve. The lower end of the spring engages a plunger member which maintains the pilot ejector member in its initial and other operative positions.
