Dahle Paper Stack and Ream Cutters are manually operated but make ease of cutting large stacks of paper at a time. Acrylic safety shields can be found on either side of the blade and will not allow the blade to move while they are in the up position. Once the safety shield is in place, you have the ability to cut cleanly though 200, 500 or 700 sheets of paper with very little effort. This clean burr free cut through such a large stack of paper is made possible through a ground Solingen Steel blade and a paper clamp that places even pressure across the entire cutting surface. A self-locking spindle driven backstop allows for minute adjustments to your cutting measurements. These cutters can be mounted on any secure table surface or on the optional floor stands. They are available in 17" and 18" cutting lengths.
