Go Deep. Getting through a 6x6 or a 4x4 with a 7 1/4-inch circ saw typically requires multiple passes, but with a Prazi Beam Cutter attached you can cut up to 12 inches in a single pass. Also available for wormdrives and hypoids, the tool is perfect for getting through heavy timbers and SIPs panels, and for gang-cutting rafters and stair stringers. It sells for $160.
