Aviation Tin Snips

The Allied Aviation Tin Snip Set delivers reliable compound-leverage cutting for thin sheet metal, aluminum, vinyl, and similar materials. Each snip features hardened and tempered carbon-steel blades with serrated edges that grip the workpiece to reduce slippage. Color-coded non-slip cushion grips (yellow = straight, red = left, green = right) allow quick identification of cutting direction, while the compound action multiplies hand force for cleaner cuts with less effort. Spring-loaded handles reopen automatically between cuts, and a locking latch keeps the jaws closed for safe storage and transport. These tools are suited for HVAC ductwork, flashing, roofing, auto body, and general sheet-metal trimming.
