ABSTRACT:
An undercut saw including a housing, a motor within said housing, a drive shaft rotated by said motor, and a blade mount mechanically linked to said shaft such that a circular saw blade mounted on said mount is rotated when the motor rotates the drive shaft. A fixed blade guard circumscribes a portion of the blade and allows selectable height adjustment of the blade. A stabilization bar on the fixed blade guard may be extended to make the device more stable. On the underside of the fixed blade guard a dust channel allows dust to be swept by the rotating blade into a dust port. The dust channel allows positioning of the dust port away from the leading edges of the fixed blade guard.
