The Wiss line of aviation snips is the most complete line on the market. Wiss aviation snips are advanced metal cutting tools originally developed for cutting extremely tough alloys used in the aircraft industry. Wiss snips are widely used in the construction trades by general contractors, HVAC professionals, sheet metal workers, dry-wallers, roofers, electricians, and siding contractors.Wiss snips offer superior cutting performance required of conventional snips to handle acute angles, complex patterns and circular shapes in galvanized steel up to 18 gauge (.049”).The jaws of Wiss aviation snips are made of durable and wear-resistant special molybdenum steel. This provides the extra service demanded by the compound lever action and withstands the severe strain of cutting heavy stock or tight curves.
