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 collar and the hole saw are coupled for positively transmitting drive torque from the arbor to the saw. In release position, the drive collar is retracted from the saw and rendered inoperative for quick and easy assembly and disassembly of the saw and arbor.
