Electric Drill Refitting Plate Shear

The item in your image is an electric drill refitting plate shear, a specialized attachment designed to transform a standard electric drill into a power shear for cutting sheet metal. [1, 2] Key Features Function: It uses the rotation of your drill to drive two circular, interlocking metal blades (geared cutters) that shear through flat metal sheets. [1] Cutting Capacity: It is generally effective for thin metals such as: Iron/Steel plates: up to ~1.0mm. Aluminum/Copper: up to ~1.5mm. [1, 2] Benefits: It provides a faster, more precise, and cleaner cut (often burr-free) compared to manual tin snips, and requires much less hand strength. [1, 2, 3]
