ABSTRACT:
A clamp arrangement for clamping saw blades to the blade holder of a power driven saw includes a seating surface formed on the end portion of a blade holder of the power driven saw for receiving the saw blade thereon. A collar surrounds the end portion of the blade holder and the shank portion of the saw blade. A threaded annular member threadably engages the collar and presses the saw blade against the seating surface and the end portion of the blade holder is, in turn, pressed against the inside wall surface of the collar. A clear passage through the annular member facilitates access to the shank portion of the saw blade held between the annular member and the seating surface whereby the shank portion can be easily removed from between the annular member and the receiving surface with the aid of an instrument passed through the clear passage in the event the blade should break off at the shank.
