The Martin Yale Powerline 620RC Ream Cutter is constructed of heavy-gauge hardened steel, using precision components. This ream cutter is designed for large run applications and general heavy use. Cut a stack of paper up to 3.14" thick or 800 sheets of 20# bond. Consistent cutting accuracy is standard to every Powerline cutter, manufactured by U.S. workers in the heart of America. The 620RC Ream Cutter comes complete with a generously sized steel table with adjustable leveling feet. The illuminated cutting line on the 620RC allows you to see exactly where the precision-ground blade will cut. In addition to this, the fine-tuned back gauge and powerful clamp virtually guarantee cutting accuracy, while the removable clamp plate helps prevent marking of carbon or other delicate papers.
