摘要： An undercut saw including a motor, a drive shaft rotated by the motor, a blade mount mechanically linked to the drive shaft, the blade mount allowing a saw blade to be mounted and a fixed blade guard circumscribing a portion of the saw blade. The fixed blade guard includes a top plate and a height adjustment skirt in telescoping attachment joined by fasteners. A guide washer with a fastener assembly is configured to move up and down in a slot on the height adjustment skirt. Turning a lead threaded member raises and lowers the top plate.

摘要： 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.

摘要： A rolling tool case for holding and transporting a tool. The case includes two sections which are joined to enclose the tool body in an interior cavity. The handle of the tool extends through an opening hole in the top of the case. The tool's handle may be gripped to roll the tool over a surface, reducing the needed size of the tool case. Wheels on the bottom of one of the two sections allow the case to roll.
