ABSTRACT:
A saw blade retention system for retaining a saw blade to a reciprocating saw includes a shaft connected to the saw for reciprocation and having a slot for receiving the saw blade. The saw blade retention system also includes a chuck disposed about the shaft and having a slot aligned with the slot in the shaft in an unlocked position for allowing the saw blade to be disposed in the slot for the shaft. The saw blade retention system further includes a cam-type mechanism for allowing the chuck to rotate angularly relative to the saw blade and shaft to a locked position to prevent the saw blade from exiting the slots and for allowing the chuck to move axially relative to the shaft to prevent axial movement of the saw blade between the chuck and the shaft. Complementary inclined surfaces are provided on the blade and the chuck to center the blade relative to its intended path of reciprocation.
