Roper Whitney punch bench bases are used to mount hand punches whilst allowing proper alignment of close-fitting punches & dies. These punch bench bases feature aluminium / steel construction to withstand the harsh industrial conditions and a rotary ball bearing mechanism for a medium-duty punching capacity, beyond that of linear punches. They further come with base screws to ensure easy mounting and can accommodate angles, channels and flanged surfaces. Choose from a huge array of these punch bench bases available in widths ranging from 2 to 7 inches on Raptor Supplies.
