Used to cut into wood bases, moldings, door jambs, and drywall to install floors under door jambs. With a 13 AMP motor and 6 1/2″ diameter flush-cutting blade, this saw can full undercut the inside corner even in extremely tight areas. Doors as thick as 1 3/4″ can be undercut without removal. Blade height is adjustable from a flush cut to a maximum of 1 1/4″ off the floor.
