ProEdge series diamond blades for the Soff-Cut 390 Saw. The Husqvarna ProEdge joint profile blades feature a unique triangular safety arbor configuration. The V-Line and Radius Line blades bevel the cut, allowing for straighter joint lines, higher production and reduced labor versus hand tooling. These blades are ideal for residential and commercial applications, including driveways, sidewalks, hardscape, patios, pool decks, parking garages and commercial sitework. With the Soff-Cutn++ system, the ProEdge blades and model 390, 50, 150 and 150 D saws can be used to chase standard joints for a beveled look the day after early entry dry-cut control joints are cut.
