Claim 0:
1. A hole saw arbor comprising:
a threaded shaft;
a non-rotatable slidable collar adapted to slide without rotation axially over an outside of threads of the threaded shaft without rotation;
an ejector mounted to a first end of the threaded shaft; and
a non-threaded shaft at a second end of the threaded shaft opposite the first end, wherein
the threaded shaft has at least one detent in a threaded portion on a flat side of the threaded shaft to hand-coerce a spring-loaded protrusion mounted in the non-rotatable slidable collar into a pre-set drilling position along the threaded shaft, whereby a hole saw is adapted to rotate on the threaded shaft over and beyond the at least one detent toward the second end of the threaded shaft, and
the non-rotatable slidable collar is adapted to hand-secure the hole saw for rotation with the threaded shaft, the non-rotatable slidable collar having a singular flat, planar surface parallel to a base of the hole saw for mating there against, the singular flat, planar surface extending 360 degrees around a full circumference of the threaded shaft.
