The Dahle Cutting Head for the 507, 3rd generation shears is an original replacement part that houses the rotary blade responsible for cutting paper, allowing the cutting mechanism to be replaced when it shows wear, without needing to replace the entire machine. It is sold in a kit of 3 units, guaranteeing sufficient replacement material for several months or years of intensive use, depending on the frequency of use of the shear. It is an essential maintenance part for offices and reprographics shops that use the shear regularly and want to maintain cutting quality over time.
