A holesaw mandrel assembly has a mandrel with a first shanking end, a
body, and a second extending end which includes a threaded spud to
receive a holesaw. A first member is secured on the second end. The first
member is axially slidable on the second end. The first member also
includes a friction surface to contact the holesaw. The friction surface
moves between a first contacting position and a second release position.
A mechanism on the mandrel moves the friction surface between the first
and second positions.
