812c Crain The completely redesigned Super Saw now has the most features and power available of any undercutting saw. The 13 AMP motor and 6 1/2" diameter flush-cutting blade can fully undercut the inside corner even in extremely tight areas. Doors as thick as 13/4" can be undercut without removal. Blade height is adjustable from a flush cut to a maximum of 11/4" off the floor. The vacuum fitting for dust control can save a lot of clean up (vacuum not included). The retractable stabilizer provides a smooth, solid feel under load. Comes with carrying case, carbide blade, masonry blade, and instructions.
