Abstract
A rotary cutting tool has an axially moveable drill pilot supported in the forward end of an arbor. A first set screw connects the arbor to an annular hole cutter. A second set screw connects the arbor to the drill pilot. The drill pilot has an integral collar that engages the inner end of the hole cutter to prevent the drill pilot from being ejected from the arbor in the event that the second set screw is disengaged from the drill pilot.
