The WISS M7R is an offset aviation snip built for general-purpose sheet metal cutting in HVAC, ductwork, and light fabrication applications. The snip measures 9.25 inches overall length with a 1.25-inch length of cut. Blades are molybdenum steel for edge retention through repeated cuts on steel up to 18 AWG. The offset handle design keeps the operator's hand elevated above the work surface, reducing knuckle contact with cut edges. Compound lever action reduces hand fatigue during extended use. A spring-action mechanism advances the blades automatically for faster, more consistent feed through curves and straight runs.
The M7R is designed for right-hand cutting and handles tight curves as well as straight cuts in sheet steel. It is commonly used by HVAC installers and sheet metal mechanics working with galvanized duct, flashing, and similar light-gauge steel stock. The non-slip serrated jaw maintains grip on the workpiece, and the textured handle grips reduce slippage during cuts. A safety latch locks the blades closed for safe transport and storage.
Designed as a general-purpose right-hand offset aviation snip suitable for cutting 18 AWG and lighter sheet steel in HVAC ductwork, flashing, and light fabrication applications.
Offset aviation snips are typically used by HVAC technicians and sheet metal mechanics working with light-gauge steel. Always engage the safety latch when the snips are not in use to prevent accidental blade contact. Wear cut-resistant gloves when handling freshly cut sheet metal edges. Inspect blades for nicks or misalignment before use and wipe blades clean after each job to extend service life.
