ABSTRACT:
To permit miter cuts clear through a workpiece, or for selected depths, a saw band carrier (6) supports a pair of saw band wheels (7, 8) above and below a workpiece support (2), and the saw band wheel carrier (6) is pivotable about a substantially vertical axis of rotation (29). The axis of rotation (29) is preferably located at the initial cutting engagement point of an endless saw band (9) looped about the saw band wheels (7, 8), and the pivoting position can be arrested at any desired pivoted or angular position. In addition, the saw band carrier can be arranged to tilt about an essentially horizontal tilt axis.
