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) driving blade (50). Base (60), supporting cutting assembly (20) above a support surface, comprises cylindrical sleeve (20) above a support surface, comprises cylindrical sleeve (63), supporting case (30) such that central axis (11) is vertical, and shroud (61) terminating in foot (98) for resting on a support surface. Case (30) and sleeve (63) are cooperatively adapted such that case (30) may 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). Vacuum attachment (100), immediately adjacent cutting area (53) to maximize collection, vacuums cuttings from blade cavity (97). Blade guard (132) rotates to an extended position covering cutting area (56) of blade (50) so as to include cutting area (56) in blade cavity (97). Wall guide (142), selectively positionable to align blade (50) with a workpiece, limits cut depth of blade (50).
