Abstract
A drive collar is non-rotatably mounted for sliding movement on an arbor between working and release positions. In working position, the drive collar is disposed adjacent the base of a hole saw which is threadably mounted on an end of the arbor, and the drive collar has a pair of drive pins projecting into holes in the base of the hole saw for positively transmitting drive torque from the arbor to the saw. The drive pins have a reverse taper to urge the drive collar toward the base of the hole saw.
