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. The 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. Dipped grips create maximum comfort while serrated lower blades provide greater material control. Available in a wide selection of styles and sizes, there's a perfect Crescent Wiss snip for every job.
