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 circular is provided which can operate in two modes. In a first mode, the circular saw operates in a conventional manner; in a second mode the circular saw can turned through 90° to operate in an undercutting mode, for undercutting a wall mounted door, for instance. To achieve this, the blade shroud comprises an outer surface facing away from the saw's motor housing which is flat for engagement with a floor surface or a guide rail. Advantageously, the outer surface might comprise a groove or channel arranged to cooperate with a guide rail rib.

摘要： An apparatus for cutting a chamfer on an upper edge of a concrete slab includes a hub designed for installation on the threaded output spindle of an angle grinder, and a specially-modified diamond-grit-edged rotary blade which mounts on the hub. For a preferred embodiment of the hub, an attachment collar is unitary and concentric with both a blade mounting flange having countersunk attachment screw holes and a blade centering shoulder on the flange. The attachment collar has at least one pair of flattened parallel sides for receiving a wrench used to tighten the hub on the output spindle. The blade, which is equipped with both countersunk attachment holes and a central positioning aperture sized to fit closely over the blade centering shoulder, is attachable with countersinking screws to the mounting flange so that the head of each screw is flush with the surface of the blade.

摘要： An undercut saw (10) having a central axis (11) generally comprises a cutting assembly (20) and a base (60). Cutting assembly (20) comprises case (30) housing electric motor (24) that drives shaft (40), upon which saw blade (50) is mounted. Base (60) supports cutting assembly (20) above a support surface and comprises cylindrical sleeve (63) supporting case (30) such that central axis (11) is vertical, horizontal portion (94), and vertical leg portion (96) extending down from the periphery of horizontal portion (94) and terminating in foot (98) for resting on a support surface. Case (30) and sleeve (63) are cooperatively adapted such that case (30) can be selectively moved vertically within sleeve (63) and retained in the selected position so as to adjust the height of blade (50) relative to foot (98). In a first preferred embodiment, case (30) and sleeve (63) include cooperating screwing devices for adjusting blade (50) height. Line cord (26) departs motor assembly (22) along central axis (11).

摘要： A device for cutting floors that attaches to the arbor on a circular saw, including an extension shaft, and an outer brace to support the extension shaft. The extension shaft extends past the outer brace a distance sufficient to permit a small trim blade, with a guard to fit under a cabinet toe kick. The small blade is held on the end of the extension shaft and is provided with a small guard. The device allows a user to place the circular saw on a floor and to position the small blade under the toe kick against the cabinet bottom to cut a line in the floor along the base of the cabinets. In one embodiment, the base plate of the circular saw is removable to allow slightly greater cutting depth. The saw attachment allows a worker to cut through a floor and sub floor around base cabinets.
