The Scoring Blades for Acrylic materials can be used with both the Excalibur 1000X Cutter & the Excalibur 5000 Cutter. This accessory is intended to be used with rigid plastics, as well as acrylics and Plexiglass. The operator need just lightly score the material, which breaks the surface tension. This allows the operator to "snap" the piece along the score line, creating a clean smooth edge. These blades will score any size acrylic that can be passed underneath the cutting bar.
