A hole saw having a saw body having a base end with a longitudinal aperture therethrough, a side wall extending from said base end and defining an interior cavity and an outer edge, and a plurality of cutting teeth formed on said outer edge; and a mandrel configured to be coupled to a source of rotational power; a saw body attachment portion mounted for rotation relative to the mandrel and a locking mechanism adapted to releasably lock the rotation of the saw body attachment portion to the mandrel, the locking mechanism having an engaged condition and a free condition wherein movement of the locking mechanism to the engaged condition releasably locks the rotation of the saw body attachment portion to the mandrel and movement of the locking mechanism to the free condition disengages the rotation of the saw body attachment portion from the mandrel, allowing independent rotation of the saw body attachment portion and the mandrel. |
