Claim 8:
9. A hole saw system comprising:
a hole saw; and
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;
a mechanical feature 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 the 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.
