VEVOR Box and Pan Brake, 610 ± 10 mm, 0-130 Degrees Sheet Metal Bending Brake, Portable Metal Bender with 20 Gauge Low Carbon Steel 14 Gauge Aluminum Capacity, 5 Adjustable Fingers for Metal Bending

The thickness of the material is adjusted mainly by the eccentric adjustment of the knife on both sides of the upper tool holder. There are hexagons on both sides, and the thickness is adjusted by the tightness of the pressure.

This model can bend low carbon steel up to 14 Gauge, which is approximately 2.0 mm (0.078 inches) thick. For materials with higher tensile strength like stainless steel, the maximum capacity is reduced to roughly 18 Gauge (1.2 mm). if this answer does not resolve the current issue, please contact us again for assistance.
