HVAC and sheet metal pros agree: When making long, straight cuts in thinner-gauge sheet metal, tinner snips are the way to go. They’re a simple, economical, and durable cutting solution for many sheet metal and HVAC applications. New Crescent Wiss lightweight aluminum and drop-forged steel tinner snips are the most durable we’ve ever made with precision ground cutting edges and an adjustable pivot bolt. Available in a wide selection of styles and sizes, there’s a perfect Crescent Wiss snip for every job. The Wiss Offset Tinner Snips are made from tempered steel for strength and durability. They cut from straight to wide left and right curves and their flat face works to efficiently guide the tool along straight lines. The large cushion grip handles allow for a secure grip even when wearing gloves.
