This professional hand metal sheet roller features a practical oblique bearing design, delivering a 0-100° bending range perfect for metal panel profiling and snap-lock panel eave installation. Its exclusive angled rollers prevent material scratches even during 90° bends, while the all-metal construction—premium aluminum alloy grip, stainless steel rollers, and secure triple-wing bolt locking—ensures long-lasting durability through heavy, repeated use. The adjustable sheet metal bender supports bending heights from 7mm to 180mm and works with 0.2mm-1.0mm thick iron sheets, ideal for both professional metalworkers and DIY enthusiasts. Equipped with height-adjustable knobs and a precise depth gauge on the central roller station, which it delivers consistent, accurate bends every time for reliable batch processing. For optimal results, ensure your material has a straight cutting edge, avoid rapid bending to prevent wrinkling, and gradually bend the material 10-20° per pass, moving the tool back and forth 5-8 times to achieve a clean 90° bend.
