Cutting a curve in sheet metal with hand snips usually ends in a wavy edge and a sore grip. A throatless rotary shear solves that by removing the frame behind the blade, so material can swing in any direction while the cut continues. Straight lines, gentle arcs, tight radii and cut-outs are all possible without repositioning the workpiece over and over. Capacity runs up to 0.06 in of mild steel, roughly 16 gauge, which is the sweet spot for ductwork, brackets, sign blanks, patch panels and craft projects. The upper and lower blades are 40Cr steel heat treated to HRC52-54, so they take repeated passes through hard material without the edge rolling. Blade clearance stays under 0.07 mm thanks to upgraded reamed-hole screws, tight enough for the classic paper test, and that precision shows up as smooth edges that need very little cleanup. The Q235 steel frame is compact but solid, with mounting holes so the shear can be bolted down to a bench or a stand. Because the whole tool weighs only about 3.97 lb and measures 12.2 by 2.76 by 14.76 in with the handle raised, it suits a small home workshop or a mobile setup just as well as a dedicated fabrication bench. Copper, aluminum and light steel all cut cleanly, making it a practical companion for repair work, studio metalwork and everyday shop tasks.
Curves as Easily as Straights: The throatless design lets sheet rotate freely under the blade, so straight lines, curves and irregular shapes are all within reach of one hand tool.
Cuts 16 Gauge Mild Steel: Capacity runs to 0.06 in thickness in Q235 steel, which covers sheet, ductwork stock and light plate common in home fabrication work.
40Cr Blades Heat Treated: Both blades are 40Cr steel treated to HRC52-54 so the cutting edge resists rolling, and the Q235 frame damps vibration for a cleaner result.
Clearance Held Under 0.07 mm: Reamed-hole screws maintain a gap tight enough to pass the paper test, so cuts come out smooth with minimal burr to file away afterward.
Compact Bench Mount: Weighing about 3.97 lb and measuring 12.2 by 2.76 by 14.76 in at full handle height, it bolts to a small bench and stores without crowding your workspace.
