The drive block has a recess defining arcuate cam surfaces. A blade clamp has a cam follower engaging the arcuate cam surfaces of the drive block. When the blade engages the work, relative movement between the cam follower and the arcuate cam surfaces on the drive block causes orbital movement to be imparted to the working end of the saw blade. Means are provided for clamping the blade holder to the drive block in two different positions. This clamping deactivates the orbital mechanism and permits the blade to be locked in two different cant positions relative to the axis of reciprocation of the drive block. | |
